The Royal Observatory at Greenwich has been one of the most important skywatching sites in history – not so much for what it told us about the stars, but for its role right here on Earth. Its location marked the starting point for measuring longitude – the position east and west on the globe. It also marked the time standard for the entire world: Greenwich Mean Time. The observatory was established on today’s date in 1675, by King Charles II. It was built on a hill near London, overlooking the Thames. Greenwich was created to provide highly accurate maps of the stars, and to measure the motions of the Sun, Moon, and planets. The work was designed to help sailors determine their longitude. Establishing longitude at sea was extremely difficult – and dangerous; many ships crashed because their navigators didn’t know where they were. The observations also played a key scientific role: they helped confirm that the motions of the Sun, Moon, and planets were governed by Isaac Newton’s laws of gravity. In 1833, the observatory began a “time service.” It dropped a ball from a tall pole at precisely 1 p.m. That allowed mariners to set their clocks before they sailed. Greenwich later transmitted the time to the whole country by telegraph, then radio. The observatory was moved in the 20th century, and closed in 1998. Today, the Greenwich site is a museum – preserving an important part of world history. Script by Damond Benningfield
Werte Hörer*innenschaft, finden Sie es nicht auch bemerkenswert, dass Daphne Bridgerton und der Duke of Hastings seit der feuchten Angelegenheit beim Royal Observatory nicht viel öfter mit einander gesehen wurden, als lediglich bei einigen Abendveranstaltungen? Erst sollte der Duke sogar auf dem Ball von Lady Trowbridge mit Abwesenheit glänzen, allerdings entschied er sich dann doch für einen späten Auftritt, nachdem er dann nach einem kurzen Gespräch mit Miss Bridgerton und einem alten Freund seines Vaters schnell wieder einen Abtritt machte. Danach waren er und Miss Bridgerton nicht mehr aufzufinden. Verdächtig? Wir denken schon. Was dahinter steckt finden wir für Sie heraus Wir halten für Sie Augen und Ohren offen, Ihre Ladies Whistlemore ---Viel Spaß mit der Folge Alle wichtigen Links über uns auf :https://linktr.ee/patmorespotcast Homepage:https://four-voices.de/patmores-potcast/ SozialeMedien: Instagram:@patmorespotcast privat: @monadifender und @dastoedchen Facebook: Patmore's Potcast Kommt auf unserenDiscord Server Supporten könnt ihr uns auf Steady, Ko-Fi oder in unseremMerchshopFür Fragen und Anregungen: Email: patmorespotcast@web.de oderpatmorespotcast@four-voices.de Wollt ihr mehr von uns hören, dann hört auch beiunseren anderen Podcast Projekten rein.

Foundations of Amateur Radio Recently I saw a social media post featuring a screenshot of some random website with pretty charts and indicators describing "current HF propagation". Aside from lacking a date, it helpfully included notations like "Solar Storm Imminent" and "Band Closed". It made me wonder, not for the first time, what the reliability of this type of notification is. Does it actually indicate what you might expect when you get on air to make noise, is it globally relevant, is the data valid or real-time? You get the idea. How do you determine the relationship between this pretty display and reality? Immediately the WSPR or Weak Signal Propagation Reporter database came to mind. It's a massive collection of signal reports capturing time, band, station and other parameters, one of which is the Signal To Noise ratio or SNR. If the number of sun spots, or a geomagnetic index change affected propagation, can we see an effect on the SNR? Although there's close on a million records per day, I'll note in advance that my current approach of taking a daily average across all reports on a specific band, completely ignores the number of reports, the types and direction of antennas, the distance between stations, transmitter power, local noise or any number of other variables. Using the online "wspr.live" database, looking only at 2024, I linked the daily recorded WSPR SNR average per band to the Sun Spot Numbers and Geomagnetic Index and immediately ran into problems. For starters the daily Sun Spot Number or SSN, from the Royal Observatory in Belgium does not appear to be complete. I'm not yet sure why. For example, there's only 288 days of SSN data in 2024. Does this mean that the observers were on holiday on the other 78 days, or was the SSN zero? Curiously there's 60 days where there's more than one recording and as a bonus, on New Years Eve 2024, there's three recordings, all with the same time stamp, midnight, with 181, 194 and 194 sun spots, so I took the daily average. Also, I ignored the timezone, since that's not apparent. Similarly the Geomagnetic Index data from the Helmholtz Centre for Geosciences in Potsdam, Germany has several weird artefacts around 1970's data, but fortunately not within 2024 that I saw. The data is collected every three hours, so I averaged that, too. After excluding days where the SSN was missing, I ran into the next issue, my database query was too big, understandable, since there are many reports in this database, 2 billion, give or take, for 2024 alone. Normally I'd be running this type of query on my own hardware, but you might know that I lost my main research computer last year, well, I didn't lose it as such, I can see it from where I am right now, but it won't power up. Money aside, I've been working on it, but being unceremoniously moved from Intel to ARM is not something I'd recommend. I created a script that extracted the data, one day at a time, with 30 seconds between each query. Three hours later I had preliminary numbers. The result was 6,239 records across 116 bands, which of course should immediately spark interest, since we don't really have that many bands. I sorted the output by the number of reports per band and discovered that the maximum number of days per band was 276. This in turn should surprise you, since there's 365 days in a year, well technically a smidge more, but for now, 365 is fine, not to mention that 2024 was a leap-year. So, what happened to the other 90 days? We know that 78 are missing because the SSN wasn't in the database but the other 12 days? I'm going to ignore that too. I removed all the bands that had less than 276 reports per day, leaving 17 bands, including the well known 13 MHz band, the what, yeah, there's a few others like that. I removed the obvious weird band, but what's the 430 MHz band, when the 70cm band in WSPR is defined as 432 MHz? I manually created 15 charts plotting dates against SNR, SSN, Kp and ap indices. Remember, this is a daily average of each of these, just to get a handle on what I'm looking at. Immediately several things become apparent. There are plenty of bands where the relationship between the average SNR and the other influences appear to be negligible. We can see the average SNR move up and down across the year, following the seasons - which raises a specific question. If the SNR is averaged across the whole planet from all WSPR stations, why are we seeing seasonal variation, given that while it's Winter here in VK, it's Summer on the other side of the equator? If you compare the maximum average SNR of a band against the minimum average SNR of the same band, you can get a sense of how much the sun spots and geomagnetic index influences the planet as a whole on that band. The band with the least amount of variation is the 30m band. Said differently, with all the changes going on around propagation, the 30m band appears to be the most stable, followed by the 12m and 15m bands. The SNR across all of HF varies, on average, no more than 5 dB. The higher the band, the more variation there is. Of course it's also possible that there's less reports there, so we might be seeing the impact of individual station variables more keenly. It's too early for conclusions, but I can tell you that this gives us plenty of new questions to ask. I'm Onno VK6FLAB

Astronomy is just like any other human endeavor. It can stir up controversy, hurt feelings – and feuds. One of its most famous feuds involved some of the giants of science – Isaac Newton, who formulated laws of gravity and motion, and Edmond Halley, the namesake of Comet Halley. Newton and Halley were colleagues of John Flamsteed, Britain’s first astronomer royal and the founder of the Royal Observatory. Flamsteed had compiled a catalog of more than 2,000 stars. It included precise positions of the stars along with other details. He showed the catalog to Halley and Newton. They were impressed, and they wanted to use its findings in their own research. So they encouraged Flamsteed to publish the catalog. But Flamsteed refused. Halley and Newton then went behind his back. With the support of the Royal Society, they published 400 copes of it, in 1712. Flamsteed was furious. He bought up all the copies he could find – and burned them. And he waged a feud against Halley and Newton for the rest of his life. The catalog wasn’t officially published until six years after his death. The first version included new designations for the stars – a number followed by the name of the constellation. One of those designations is 32 Leonis. The star is better known as Regulus – the brightest star of Leo. And it’s especially easy to spot tonight. It’s above the Moon as they climb into good view, around 9 or 9:30.

CrowdScience listeners David and Tatiana have long been captivated by an unusual dinner table discussion: the peculiar change they've noticed over the past 16 years in the sunlight streaming through their bedroom window in Ostend, Belgium. They're convinced that the room has not only become sunnier but that the actual angle of sunlight has shifted.Intrigued by their observations, we head to Ostend. Our mission: to investigate three of their theories, enlisting expert help along the way.Theory 1 – A celestial anomaly? René Oudmaijer at the Royal Observatory of Belgium considers whether our shifting position in the solar system might explain the change.Theory 2 – Movement in the Earth's crust? Alejandra Tovar from the Geological Survey of Belgium examines tectonic data to see if the Earth's crust is moving enough to alter the angle of sunlight.Theory 3 – Subsidence? Structural engineer Kath Hannigan helps us inspect the building for signs that it may be sinking or twisting.And we explore one final theory of our own, enlisting memory expert Julia Shaw to examine whether it could all be a trick of the mind. Will the team crack the case?Presenter: Caroline Steel Producer: Harrison Lewis Editor: Cathy Edwards Production co-ordinator: Ishmael Soriano Studio Manager: Sarah Hockley(Photo: CrowdScience listeners David and Tatiana standing in front of a window in their house)

2/4: The Asteroid Hunter: A Scientist's Journey to the Dawn of our Solar System Hardcover – March 19, 2024 by Dante Lauretta (Author) https://www.amazon.com/Asteroid-Hunter-Scientists-Journey-System/dp/1538722941 On September 11, 1999, humanity made a monumental discovery in the vastness of space. Scientists uncovered an asteroid of immense scientific importance—a colossal celestial entity. As massive as an aircraft carrier and towering as high as the iconic Empire State Building, this cosmic titan was later named Bennu. Remarkable for much more than its size, Bennu belonged to a rare breed of asteroids capable of revealing the essence of life itself. But just as Bennu became a beacon of promise, researchers identified a grave danger. Hurtling through space, it threatens to collide with our planet on September 24, 2182. Leading the expedition was Dr. Dante Lauretta, the Principal Investigator of NASA's audacious OSIRIS-REx Asteroid Sample Return Mission. Tasked with unraveling Bennu's mysteries, his team embarked on a daring quest to retrieve a precious sample from the asteroid's surface — one that held the potential to not only unlock the secrets of life's origins but also to avert an unprecedented catastrophe. A tale of destiny and danger, The Asteroid Hunter chronicles the high-stakes mission firsthand, narrated by Dr. Lauretta. It offers readers an intimate glimpse into the riveting exploits of the mission and Dr. Lauretta's wild, winding personal journey to Bennu and back. Peeling back the curtain on the wonders of the cosmos, this enthralling account promises a rare glimpse into the tightly woven fabric of scientific exploration, where technical precision converges with humanity's profound curiosity and indominable spirit. 1910 Royal Observatory at Greenwich

rWotD Episode 2460: David Robertson (engineer) Welcome to random Wiki of the Day where we read the summary of a random Wikipedia page every day.The random article for Sunday, 28 January 2024 is David Robertson (engineer).David Robertson (1875 – 1941) was the first Professor of Electrical Engineering at Bristol University. Robertson had wide interests and one of these was horology – he wanted to provide the foundation of what we could call “horological engineering”, that is, a firm science-based approach to the design of accurate mechanical clocks. He contributed a long series on the scientific foundations of precision clocks to the Horological Journal which was the main publication for the trade in the UK; he and his students undertook research on clocks and pendulums (some funded by the Society of Merchant Venturers); and he designed at least one notable clock, to keep University time and control the chiming of Great George in the Wills Memorial Building from its inauguration on 1925, for which he also designed the chiming mechanism.Today, we get accurate time from atomic clock ensembles in observatories round the world, compared and distributed by GPS satellites and over the internet, and displayed on almost any public or personal screen. Accurate time has become ubiquitous and its maintenance a branch of information and communications technology. A century ago none of this existed, and the world depended on the pendulum clock to keep its time, referenced to astronomical observations. There was a scientific literature on the behaviour of pendulums and clocks; and a widespread craft-based industry making timepieces; but it could not be said that horology was a branch of engineering.Robertson became Professor of Electrical Engineering in Merchant Venturer’s Technical College in 1902. MVTC merged with University College Bristol when the latter was granted a Royal Charter in 1909 and became the engineering faculty of the new University of Bristol – Robertson then became the first professor of the subject in the faculty. He served in this post until his death in 1941. Clock-wise, the Shortt Synchronome Free Pendulum clock entered service at the Royal Observatory in 1923 and kept Greenwich, and therefore the nation’s, time until supplanted by quartz clocks in the 1940s. Throughout Robertson’s career therefore, pendulum time was paramount. Suppliers such as the Synchronome Company or Gents of Leicester could by 1925 have supplied perfectly satisfactory and well-proven systems to run the bell and slave clocks throughout the building. The fact that the University chose to commission a unique and original design is a tribute perhaps to its pride in the new building and to its distinguished Professor, who was able to put into practice the principles that he had developed.The Robertson ClockOriginally mounted in an interior foyer of the Wills Memorial Building, Robertson's clock is housed in an oak case 1753 x 837 x 310 mm (h/w/d), originally carried on stout oak “dogs” let into the masonry of an internal wall. The case was also secured to the wall through its back, but does not support any of the mechanisms, which are separately mounted through the case back into the wall using studs. The opening front door is fully glazed. In its new home in Queen’s Building the original studs are re-mounted on to a large steel plate, firmly screwed to the reinforced concrete wall.At the top of the case a clock dial displays hours and minutes as kept by the pendulum. The dial is a standard Gents slave clock movement which is advanced by a pulse every 30s, counted down from seconds pulses generated by the pendulum. Additional circuits in the clock once generated other half-minute pulses that controlled 3 strings of similar slave clocks throughout the building.Right down the centre of the case is the pendulum, of the order of a metre long and with a period of 2 seconds. It is suspended from a bracket attached to a massive iron casting bolted through to the wall, which also carries the “escapement” mechanism to the right under the face. This drives the pendulum with a small impulse of force every second, generated by the drop of a small weight under the control of an electromagnet. Part of the mechanism includes a 60-tooth ratchet wheel advanced on every pendulum swing by a pawl driven by the electromagnet. Originally this operated a pair of contacts by two pins on its periphery to generate the half-minute pulses, but at some stage these contacts were removed.To the left of the pendulum is the regulator. This is arranged to apply a small force to the pendulum which through an ingenious linkage effectively works against gravity, slowing the pendulum down. The force comes from a torque generated by a spiral hair-spring, one end being attached to the pivot of a lever that forms part of the escapement linkage, the other to a disk that can be rotated in small steps by a solenoid-operated “stepper motor”. This allows the period of the pendulum to be adjusted by changing the torque, under the control of a system that compares the pendulum phase to a time standard (originally a daily pulse sent out over the telegraph network at 10.00 GMT).Behind the pendulum and near its top is a standard aneroid barometer, and below that a mercury thermometer. These would have been used when checking the clocks’ rate, which depends on both atmospheric temperature and pressure.To the left of the pendulum is the Civil Time Unit (CTU). This is essentially a clock that receives a pulse every second from the pendulum and keeps track of local time, GMT or BST depending on the season, to control the pulses sent to Great George to make it chime on the hours, 0700 through 2100 except Sundays. The CTU was driven by its own electromagnet.On the right is the Greenwich Time Unit (GTU), which essentially kept GMT by counting seconds impulses but also controlled the sequencing of the synchronising system around 10.00 am GMT every day. Again, the GTU had its own electromagnet drive.Behind the wall to which the clock was mounted there was a Control Box that housed several terminal frames, some relays, and ancillary components, that were connected to contacts on the TUs by wires going through the wall.

The iconic ball dropping trend on New Year's Eve has a fascinating history with both ancient and modern roots. Here's a breakdown: Ancient Roots: Time Balls: The concept of a ball dropping to mark time predates the Times Square ball by centuries. In 1833, the Royal Observatory in Greenwich, England, installed a "time ball" that dropped at 1 pm daily, allowing ships' captains to set their chronometers. Similar time balls popped up around the world, though few remain functional today. Modern Origins: Times Square and Fireworks: Back in 1904, Times Square, then named Longacre Square, was already drawing crowds for New Year's Eve celebrations. The New York Times, residing in the newly built Times Tower, held rooftop fireworks displays to mark the occasion. The First Ball Drop: In 1907, seeking a more visible alternative to fireworks during a dim winter night, Times Square organizer Adolph Ochs opted for a 700-pound illuminated ball to descend from the Times Tower flagpole at midnight. This marked the official birth of the Times Square ball drop tradition. Evolution and Popularity: The ball has undergone several design changes over the years, becoming lighter, brighter, and incorporating various themes. The tradition exploded in popularity, broadcast nationally through radio and later television, making it a symbol of New Year's Eve celebration not just in New York City, but for the whole world. Other Influences: Times Square as a Festive Hub: Beyond the ball, Times Square's vibrant atmosphere, live entertainment, and celebrity appearances added to the allure of the event, further solidifying its status as a global New Year's Eve destination. Global Adaptations: While the Times Square ball drop remains iconic, countless cities around the world now hold their own versions, featuring a variety of dropped objects that reflect their local culture and traditions. So, the trend of dropping objects on New Year's Eve has both ancient practical roots and a modern story intertwined with the evolution of Times Square and media technology. The tradition continues to evolve, captivating audiences worldwide as a dazzling countdown to a fresh start. --- Send in a voice message: https://podcasters.spotify.com/pod/show/moodkillers/message

AN HOUR OF PEACE OF MIND IN THE JOYS OF THE UNDISCOVERED: 1/8: The Elephant in the Universe: Our Hundred-Year Search for Dark Matter by Govert Schilling (Author), Avi Loeb (Foreword) https://www.amazon.com/Elephant-Universe-Hundred-Year-Search-Matter/dp/0674248996 In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos―some unknown elementary particle. Yet so far dark matter has escaped every experiment. Indeed, dark matter is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Schilling interviews both believers and heretics and paints a colorful picture of the history and current status of dark matter research, with astronomers and physicists alike trying to make sense of theory and observation. 1945 ROYAL OBSERVATORY, PART DESIGNED BY CHRISTOPHER WREN

BIG BANG THEORY PUZZLING WITH JAMES WEBB REVELATIONS: 4/4: Flashes of Creation: George Gamow, Fred Hoyle, and the Great Big Bang Debate, by Paul Halpern https://www.amazon.com/gp/product/B08PV5CLZQ/ref=dbs_a_def_rwt_hsch_vapi_tkin_p1_i0 A respected physics professor and author breaks down the great debate over the Big Bang and the continuing quest to understand the fate of the universe. Today, the Big Bang is so entrenched in our understanding of the cosmos that to doubt it would seem crazy. But as Paul Halpern shows in Flashes of Creation, just decades ago its mere mention caused sparks to fly. At the center of the debate were the Russian-American physicist George Gamow and the British astrophysicist Fred Hoyle. Gamow insisted that a fiery explosion explained how the elements of the universe were created. Attacking the idea as half-baked, Hoyle countered that the universe was engaged in a never-ending process of creation. The battle was fierce. In the end, Gamow turned out to be right—mostly—and Hoyle, along with his many achievements, is remembered for giving the theory the silliest possible name: "the Big Bang." Halpern captures the brilliance of both thinkers and reminds us that even those proven wrong have much to teach us about boldness, imagination, and the universe, itself 1882 Royal Observatory.

17 May 2023: In this episode of the Dark Matter Podcast, join Germain Garreau and Kaustubh Hakim, two researchers who detect and study exoplanets – or planets that orbit a star outside our solar system. The podcast details their new techniques and nulling interferometry , which involves using several small telescopes instead of one large one. However, reaching near-perfect symmetry between the beams of each telescope is a challenge. The podcast also delves into how scientists today can infer the chemical composition of exoplanets from a distance and a question that has many in the scientific community entranced: can we use bio-markers like the detection of ozone to tell us whether there is life outside our solar system? Germain Garreau is an engineer in optics and photonics at Grenoble INP-Phelma (France) and KTH (Sweden), and a PhD student at the Institute of Astronomy of KU Leuven. His work on instrumentation is dedicated to pushing the limits of exoplanet's imaging and their characterisation using interferometry. Kaustubh Hakim is a Senior Researcher at KU Leuven and Royal Observatory of Belgium, who is currently building a new research team at the intersection of astronomy and geosciences to unravel mysteries surrounding exoplanets.
Dr. Bryan Gillis is back! This time he's here to teach us about gravitational lensing. And along the way, we learn about dark matter and dark energy! What the hell are they?

The history of time and how it relates to the maritime world is one of the most significant chapters in global history. The question of time is nothing less than the question of civilisation; the question of us. Time itself has been harnessed, politicised and weaponised; clocks have been used to wield power, make money, govern and control; to exchange knowledge and even beliefs. For the maritime world, the history of time takes us from some of the most ingenious inventors and scientists the world has ever seen to the spread of empires around the globe. To find our more Dr Sam Willis spoke with David Rooney, an expert on the history of timekeeping and civilisation who has worked as the Curator of Timekeeping at the Royal Observatory in Greenwich and is the author of ‘About Time: A History of Civilisation in Twelve Clocks.'

And I finish the year, right here, where I started it – home, with my parents, my family, full of gratitude (and food) and ready to go again. The thing that I found so jarring about 2022 was the huge contrast between development and destruction. But there are reasons to be cheerful too. Cooperation. I see it everywhere. By working together, we're able to create something that is much greater than the sum of its parts. By sharing scientific knowledge, we've been able to make incredible strides in our understanding of the universe, and by sharing technological knowledge, we've been able to develop advanced tools and machines that have made our lives easier and more comfortable. Cooperation is essential for our survival. We are a social species. We depend on each other for protection, for food, and shelter. By working together, we are able to accomplish incredible things and ensure our survival in the universe. Reading the works of Ryan Holiday and hearing about stoicism has taught me that perspective and discipline is important. Priorities are important. You – I – am important. Millions of years ago, the human experiment began. And here you are; a miracle. If ever the world feels awful, if ever – like me – you get stuck in your own head, think bigger. The very molecules that make up your body come from the universe – the same galaxies that James Webb snapped, the same rock that Orion soared past… You are made of those. We are all connected and together, we can achieve amazing things. That perspective is important. Remember that as we head into 2023.

So Join Secular Rarity kicking off this episode with new comer Dr Richard Firth-Godbehere, Nate Smith and myself for the latest episode. Will I finally get myself canceled? You be the judge!Up first, we ARE in Kansas, and they voted FOR abortion? What the whaa…? Yes it's true, Kansas has voted to keep abortion protections in their state constitution. Does this mean Kansas is going Democrat? Well, there is so much more to it than that. We would have called it a step in the right direction, but it is going to take some wait and see to know where we are at.Next, we check in with the original residents of the US as they suspend Christian Missionary work! Seem they didn't care for Christians saying Jesus is the only god and trampling over their spirituality and culture. I mean Americans wouldn't do that… again… and again… Well this didn't age well.Speaking of Christians, we look into how Christian Nationalism has gone mainstream. Yes, yes, the Lamestream media is now filled with hatred and your favorite congresspeople MTG and Boebert are leading the charge. I'm sure they are just happy they can finally say their quiet parts loud and proud?Lastly, we take a bit of a Looking Back at the creating of the Royal Observatory and a few of their discoveries. These discoveries would go on to teach generations about our world, the universe, and our place in it. Bringing out the truth of our universe starting, and what the Bible thinks happens. Lessons that will stand the test of time, until YouTube starts to exist…. Oops.That about wraps it up for this week.

Marcella's interest in astronomy and atmospheric optical phenomena (photometeors) over time led her to create a scientific dissemination site (www.greenflash.photo) with about 1000 photometeor images and videos, even rare ones, observed throughout Italy and above all on the Iblei mountains (Rg) and on the Dolomites in Cadore, landscapes chosen for the great diversity of orographic, climatic and day and night luminosity, as well as for their position at the two extreme latitudes of Italy. In 2011 he received from the Minister of Public Administration the national prize for innovation in teaching in schools "Innovascuola". In 2015, his photo "Moon and Antelao" is included in the Shortlist of the Royal Museum of Greenwich photo competition "Astronomy Photographer of the Year", which selects the best astrophotography of the year from all over the world. The photo was then also published in the volume "Astronomy Photographer of the Year 2015" published by the Royal Observatory of Greenwich in collaboration with the BBC, the photographic site Flickr and the Collins publishing house and exhibited inside the Astronomical Observatory of Greenwich.The same photo will become the December image of the 2017 Greenwich Astronomical Observatory calendar. In 2016 he exhibited his photos in a personal exhibition in San Vito di Cadore (Bl), with more than 100 photos of atmospheric optical phenomena from all over Italy. The event was the first exhibition in Italy complete with video dedicated to photometeors. The work of dissemination through video and photography continues in the following years and many of his images are published by the major national astronomy magazines (Colelum Astronomia, Nuovo Orione and Le Stelle, Focus) and internationally (Astronomy Now, Sky and Telescope) as well as by websites of primary scientific importance such as those of Spaceweather, USRA and NASA. In 2016, he documents the visibility of the Maltese archipelago from the province of Ragusa and his images and his videos are broadcast by the Maltese national TV which, in the interview, define his works as the first shots of the Maltese archipelago by the iblei. Since 2017 he has been a member of the board of directors of CISA (Centro Ibleo Studi Astronomici), UAI delegation (Unione Astrofili Italiani) for the province of Ragusa, which aims to actively promote astronomy in the province of Ragusa, contributing with conferences on atmospheric optics. In September 2018, NASA publishes an image of him that captures the Moon setting next to the active crater south-east of Etna. In 2019 the national magazine "Nuovo Orione" publishes the calendar with its images: 12 photos that tell the sky of the Dolomites and the Iblei. For the summer solstice of 2019, NASA publishes his work on the solar Analemma, a work selected for its didactic value and for the singularity in creating an "Analemma at sunset".On May 31, 2020, his photos of the Green Ray taken on the Sun, Moon and planets, become NASA 's photo of the dayIn the summer of 2020 he sets up two twin exhibitions, in northern and southern Italy, between the municipality of Isnello (PA) and San Vito di Cadore (Bl) On September 26, 2020, his photo Moon Pairs and the Synodic Month ” becomes NASA 's photo of the dayOn November 11, 2020, his “Colors of the Moon” photo becomes NASA 's photo of the dayOn October 16, 2021, on the occasion of the “International Observe the Moon Night 2021”, NASA chooses its photographic work, created in collaboration with Gianni Sarcone, “ Moona Lisa ” as the astronomical photo of the day.Collaborate on the 2021 calendar of “ Severe Weather Europe” for the month of February For professional deformation, he always combines his passion for photometeors with his profession, focusing his works on the didactic, informative and originality value, trying to grasp what has never been produced yet, simplifying to make it affordable for everyone.Component of the Pictores Caeli is a group of astrophotographers born to share ideas and suggestions on astrophotography. The goal is the union of mutual technical and artistic skills to develop high quality images, certified by a shared brand.The purpose of Pictores Caeli is to restore the sense of wonder that one feels at the moment of observation and shooting, narrating sidereal events, contrasts between architectural and natural elements, and stimulating suggestions that go beyond phenomenal objectivity through the photographic medium.Although a lens and an observation point determine an interpretation of reality, Pictores Caeli follows a shared protocol in order not to alter the scientific data, using and experimenting with the best shooting and post-production techniques.Photography for Pictores Caeli is conceived as an art form, and represents a moment of contemplation, growth, knowledge, research, experimentation and sharing.

This Slow Radio feature takes us on a leisurely stroll round the park. Parks are always important but during the lockdowns they've become vital to people stuck in cities and towns. Children can still play in the park; grown-ups can still walk, run and even dance there.When a smattering of snow fell in London recently Greenwich Park erupted with people - of all ages - pouring like lava down the icy slopes below the Royal Observatory, on sledges, tin trays, even grill pans. There were snowball skirmishes and snow sculptures appeared. It was a wonderful sight, and even more arresting were the sounds - the cacophony of joy.The park these days is 'full of noises, sounds and sweet airs, that give delight, and hurt not', the sounds of life and happiness. But, in the distance you hear, too, the sounds of sorrow - a church bell tolls and ambulances wail. Today's Slow Radio programme gathers all these - the birds, the dogs, the children, runners, boxers, ice, mud, rain, and the - almost - silence, capturing a winter's Sunday in the Park With...sound.Producer: Julian May
This week's episode is a re-upload of Episode 1, Martial Bourdin. I've just upgraded my microphone and picked up a mixing desk, and the first, 10? 15?? Maybe 20??? Episodes needed a do-over. On off weeks, time permitting, I'm planning on dropping new versions of those early episodes. At 4:45pm precisely, GMT, 15th February 1894, the grounds of Greenwich Park, London – home of the Royal Observatory, and a clock we'll discuss later – are shaken by a resounding boom. Staff at the observatory recalled a “sharp and clear detonation, followed by a noise like a shell going through the air”. Peering through windows in trepidation, they attempted to work out what just happened. A park warden and a group of students ran towards the epicenter of the blast – where a solitary young man lay dying. The young man, who died not long after in a local hospital, was identified as 26 year old Frenchman Martial Bourdin. Just who was this young man, and why was he carrying a bomb through the park on a cold winter day? The blog post of the episode is here.

Deneys Reitz had broken his own leg in a freak accident and was still hobbling about, his compound fracture causing some pain. General de la Rey ordered him to a small medical camp behind the lines near Hartbeespoort which is west of Pretoria. There he was recovering when the British launched an attack on the Boers. Reitz saddled his horse and galloped to the ridge overlooking the British. But there was no much they could do - there were about 12 000 English versus 600 Boers. The casualties were light, although the British artillery were accurate enough and caused the Boers to fall back from ridge to ridge. By two in the afternoon the English gave up the chase. They rested their horses after the Generals' ironic speech, and then under the cover of dark rode further away. An amazing sight greeted the men as they crested a rise that night - it was called the Great Comet of 1901, Comet Viscara. But as they rode, a boyish voice from the darkness called out Vlug means retreat, another example of the sense of humour of soldiers making the best of a bad situation. The Royal Observatory in Cape Town, the Argentine National Observatory and the Government observatory in Perth Australia shared their scientific evaluation which put the Comet at 79 million miles from Earth. While the comet caused the Prophet van Rensburg some excitement, there was more excitement in the Cape. Kritzinger was back in the Midlands and causing trouble, while Gideon Scheepers was about to commit a war crime. He shot dead two black troops who'd fired on his men from a farmhouse, saying "it was a white man's war". He was to pay for that act with this life after being captured.
Wierd fiction presents the universe as an irrational place, totally indifferent to human concerns. Is 'the wierd' a more general approach that can bextended beyond fiction to encompass the other arts, or even politics and science? Rana Mitter discusses the idea of the wierd with literary scholar Nick Freeman of the University of Loughborough, cultural theorist Caroline Edwards of Birkbeck, University of London, and astronomer Marek Kukula of the Royal Observatory at Greenwich. Continuing to explore the faultline between art and science, Rana meets artist Helen Pynor and gallery director Mike Stubs to discuss science and art on show at Liverpool's FACT. And, we discuss the new Japanese animated film Your Name with Japanologist Irena Hayer of the Univeristy of Leeds, and Justin Johnson, curator of animation and films for younger people at the British Film Institute. No Such Thing As Gravity is on show at FACT, Liverpool until February 5th 2017. Your Name is on release at selected cinemas throughout the country now. Producer: Luke Mulhall
Astronomer Marek Kukula from the Royal Observatory at Greenwich explores the scientific implications of the forthcoming transit of Venus across the face of the Sun, a rare astronomical event that will not occur again until 2117. Previous transits have helped establish fundamental facts about our solar system, including the distance and relative positions of all the planets that orbit our sun. But now, the forthcoming transit in June 2012, the last this century, will help planet hunters searching for other worlds across the galaxy (exo-planets). As Marek discovers, technology now makes it possible to pinpoint not only a planet's mass, size, and distance from its star but we can also establish whether it has an atmosphere and what that atmosphere might consist of and therefore whether it could theoretically support life. Thanks to the next transit event, the search for another Earth has taken a bold step forward.(Image: Venus (black dot) is silhouetted as it orbits between the Sun and the Earth during the transit of Venus seen from Bangkok on 6 June 6 2012.

Melvyn Bragg and his guests discuss the measurement of time. Early civilisations used the movements of heavenly bodies to tell the time, but even in the ancient world more sophisticated timekeeping devices such as waterclocks were known. The development of mechanical clocks in Europe emerged in the medieval period when monks used such devices to sound an alarm to signal it was the hour to pray, although these clocks did not tell them the time. For hundreds of years clocks were inaccurate and it proved hard to remedy the problems, let alone settle on a standard time that the country should follow. It was with the advent of the railways that time finally became standardised in Britain in the mid-19th century and only in 1884 that Greenwich became the prime meridian of the world. Atomic clocks now mark the passing of the days, hours, and minutes and they are capable of keeping time to a second in 15 million years.

As part of the BBC's year of science programming, Melvyn Bragg looks at the history of the oldest scientific learned society of them all: the Royal Society. Programme two begins in the coffee house Isaac Newton and the fellows of the early 18th century frequented. At the Royal Observatory, Greenwich, we learn how Newton's feud with the Astronomer Royal John Flamsteed tested the lines between government-funded research and public access. In the age of exploration, senior fellows accompany naval expeditions, such as Cook's expedition to Tahiti and subsequent discovery of Australia. International relations are fostered between scientists such as Benjamin Franklin, whose house in London serves as live-in lab and de facto American embassy. By the end of the century the President, Sir Joseph Banks, successfully embeds the Royal Society in the imperial bureaucratic hub of the new Somerset House. But while senior fellows concentrated on foreign fields, a more radical, dissident science and manufacturing base wrought the Industrial Revolution right under their noses.
