Achieving perihelion at a distance of 7.26 million kilometres from the Sun's surface, the probe travelled at an astonishing 635,266 kilometres per hour. This milestone marks the midpoint of the mission's 20th solar encounter, with more close approaches planned for the future.- **China's Secretive Space Plane**: China's highly secretive reusable space plane has released another mysterious spacecraft into orbit. The experimental spacecraft, named Sheng Long or "Divine Dragon," has been in orbit for nearly 200 days on its third mission. Launched aboard a Long March 2F rocket, the space plane's activities remain shrouded in mystery, with speculation about its sub-satellite designed for proximity and recapture spy manoeuvres.- **Seeing the Universe in Radio Waves**: Back in 2016, the Murchison Widefield Array telescope in Western Australia provided a glimpse of the universe as it would appear if human eyes could see radio waves. The GLEAM survey catalogued around 300,000 galaxies, revealing the remnants of distant star explosions, galaxy collisions, and the activities of supermassive black holes. This groundbreaking research offers invaluable insights into the universe's structure and the physics of distant galaxies.00:00:00 " This is spacetime series 27, episode 87, for broadcast on 19 July 202400:00:46 " NASA's Parker solar probe just completed its 20th close approach to the sun00:05:03 " Large scale radio surveys like Gleam are extremely valuable to scientists00:10:44 " I have student looking for transient m objects in our survey00:16:27 " A new study claims modern dingoes share very little ancestry with other breeds00:18:11 " New research finds people who invest in cryptocurrency more likely to hold fringe viewsFollow our cosmic conversations on X @stuartgary, Instagram, YouTube, and Facebook.

Foundations of Amateur Radio Today I'm going to spend a little longer with you than usual, but then, I think this is important and it's good to end the year on a bang. Have you ever attempted to make contact with a specific DXCC entity and spent some time exploring the band plan to discover what the best frequency might be to achieve that? If you got right into it, you might have gone so far as to attempt to locate the band plan that applies to your particular target. If you have, what I'm about to discuss will not come as a surprise. If not, strap yourself in. When you get your license you're hopefully presented with a current band plan that is relevant to your license conditions. It shows what frequencies are available to you, which modes you can use where, and what power levels and bandwidth are permitted. It should also show you if you're the primary user or not on a particular band. If you're not sure what that means, some frequency ranges are allocated to multiple users and amateur radio as one such user is expected to share. If you're a primary user you have priority, but if you're not, you need to give way to other traffic. It should come as no surprise that this is heavily regulated but as a surprise to some, it changes regularly. Across the world, frequency allocation is coordinated by the International Telecommunications Union, the ITU, and specifically for amateur radio, by the International Amateur Radio Union, the IARU. It coordinates frequencies with each peak amateur radio body. The ITU divides the world into three regions, Region 1, 2 and 3, each with its own band plan. Within each region, a country has the ability to allocate frequencies as it sees fit - presumably as long as it complies with the ITU requirements. As a result, there's not one single picture of how frequencies are allocated. And this is where the fun starts. In Australia there's an official legislated band plan, cunningly titled F2021L00617. It contains the frequencies for all the radio spectrum users as well as a column for each ITU region. The document is 200 pages long, and comes with an astounding array of footnotes and exclusions. It's dated 21 May 2021. There's a simplified version published by the Wireless Institute of Australia, which comes as a 32 page PDF. It was last updated in September 2020. When I say "simplified", I'm of course kidding. It doesn't include the 60m band which according to the regulator is actually an amateur band today. The 13cm band according to the WIA shows a gap between 2302 and 2400, where the regulator shows it as a continuous allocation between 2300 and 2450 MHz. The point being, who's right? What can you actually use? Oh, the WIA does have a different page that shows that 6m "has had some additions", but they haven't bothered to update their actual band plan. To make life easier, the regulator includes helpful footnotes like "AUS87". This is particularly useful if you want to search their PDF to determine what this actually says, since it only appears 156 times and it's not a link within the document. In case you're curious, it's related to three radio astronomy facilities operated by the Commonwealth Scientific and Industrial Research Organisation, better known as the CSIRO, two by the University of Tasmania and one by the Canberra Deep Space Network. Interestingly the Australian Square Kilometer Array and the Murchison Widefield Array don't feature in those particular exclusions, they're covered by footnote AUS103. If that wasn't enough. The regulator has no time for specific amateur use. You can find the word Amateur 204 times but there's no differentiation between the different classes of license which means that you need to go back to the WIA document to figure out which license class is allowed where, which of course means that you end up in no-mans land if you want to discover who is permitted to transmit on 2350 MHz. If we look further afield, in the USA the ARRL publishes half a dozen different versions, each with different colours, since black and white, grey scale, colour and web-colour are all important attributes to differentiate an official document. Of course, those versions are now all six years out of date, having been revised on the 22nd of September 2017. The most recent version, in a completely different format, only in one colour, has all the relevant information. It shows a revised date of 10 February 2023, that or, 2 October 2023 because of course nobody outside the US is ever going to want to refer to that document - seeing as there's only amateurs in the USA, well at least according to the ARRL. Interestingly the US Department of Commerce, the National Telecommunications and Information Administration, Office of Spectrum Management publishes a colourful chart showing the radio spectrum between 3 kHz and 300 GHz. You can't use it as a technical document, but it's pretty on a wall to amaze your non-amateur friends. The FCC has a band plan page, but I couldn't discover how to actually get amateur relevant information from it. If you think that's bad, you haven't seen anything yet. The British are special. The RSGB publishes a variety of versions, each worse than the next. It appears that their system creates a single HTML page for each band, their 32 page PDF is a print out of that and their interactive viewer wraps all that into some proprietary system that makes using it an abysmal experience. Fortunately, they also link to a band plan made by the regulator, presented as a five page PDF which is much more concise and has the helpful heading: "The following band plan is largely based on that agreed at IARU Region 1 General Conferences, with some local differences on frequencies above 430MHz." Unfortunately it doesn't specify which particular General Conferences apply, but it does helpfully tell us that it's effective from the first of January 2023, unless otherwise shown. That said, 2023 only appears in the headers and footers and 2024 doesn't appear, so who knows what date exceptions exist. One point of difference is that the RSGB also publishes their band plan as an Excel Workbook. This might start your heart beating a little faster with visions of data entry, sorting, filtering and other such goodies, like figuring out which frequency to use for a particular mode. Unfortunately the authors have used Excel as a tool for making tables like you'd see in a word processing document. Start and Stop frequencies in the same cell, random use of MHz, spacing between bandwidth and frequencies and descriptions intermingled. In other words, this is not an Excel Workbook and it does not contain information in any usable form, unless you want to do some free text searching across the 32 worksheets - what is it with 32 anyway? Perhaps this is their authoring tool and they save as HTML from within Excel or print to PDF. Who knows? One point that the British do get right is version control. You can see specifically what change was introduced when. For example, on the 6th of March 2009 the 17m QRP frequency was corrected to 18086 kHz. Mind you, there's several pages of updates, helpfully scattered across multiple worksheets. Yes, they're really using Excel as a word processor. Before I dig into any other countries, I should mention the United Nations Amateur Radio peak body, the IARU, presumably a model that countries should aspire to. The IARU has links to three different sets of band plans. Region 1 breaks the band plan into HF and higher frequencies and the higher frequencies are broken into notional bands, each with their own PDF. Regions 2 and 3 each provide a single PDF, but the Region 3 document is hosted on the Region 2 website. Region 1 documents contain a revision and an active date as well as an author. Region 2 and 3 documents contain a date and are formatted completely differently. In Germany the DARC attempts to link to the IARU-Region 1 band plan, but the link is pointing at a non-existent page. In the Netherlands, VERON points at a 2016 edition of the IARU-Region 1 HF band plan and the current Region 1 mixed band plan for higher frequencies. In Canada the RAC points at a HTML page for each band and presents all the HF frequencies as a single image, yes an image. All the other bands are essentially text describing how to use a particular band. The HF image states that it applies from the first of June 2023, the rest of the pages carry various dates that conflict with each other. For example, the 2m band states on the landing page that it was updated on the 23rd of September 1995, but the page itself refers to a new 2m band plan that was approved in October of 2020. The linked band plan contains all the credit, who is responsible for the plan, naming the entire committee, adding notes and requesting donations, straight from the RAC newsletter, page 36 and 37 of the November / December 2020 edition, rather than providing a stand-alone technical document. Let's hop back across the Atlantic and see what else we can learn. In Switzerland things are a little different. Its regulator publishes a frequency allocation plan that is a thing of beauty. It presents as a table on a web page, but it has a search box you can use to filter the frequencies that you're interested in. So if you use the word "amateur", you end up seeing the whole amateur radio spectrum as it exists within the borders of Switzerland. You can also set frequency ranges and as a bonus, if you type in 1 MHz and change the unit to kHz, it actually changes the number to 1000. As I said, a thing of beauty. Oh, and the footnotes? Yeah, they're links and they open a new window with the relevant information, and you can keep clicking deeper and deeper until you get to the actual legislation driving that particular entry. If that's not fancy enough for you, from within the search, you can download an offline HTML copy, you can pick services, rather than use search terms, and the PDF version, because of course there is one, actually has the same active links to footnotes. That said, it has some idiosyncrasies. It specifies when amateur radio is the primary or the secondary user of a band, except when it doesn't. I presume that this is a regulatory thing and that it's a shared resource, but as an outsider I'm not familiar with Swiss law, but if I was inclined, I could become familiar, since the documents are all written in multiple languages, including English. Another oddity is that some frequencies show no text at all, but I presume that's a bug, rather than by design. Speaking of bugs, or features, depending on your perspective. Consider the frequency 2300 MHz. Every single document I looked at mixes up how this is shown. Some have a space between the number and the unit, some don't. Some countries put a space between the 2 and the 3, some a dot, some a comma, the Swiss use an apostrophe. Just so we're clear, these are technical documents we're talking about. They're not literary works, there are standards for how to do this, but it seems that the people writing these documents are blissfully unaware of any such references. Even the IARU cannot agree on how to represent the same number, let alone use the same formatting for the same band plan in each of its three regions. At this point you might come to the conclusion that this is all an abhorrent mess and I'd agree with you. In my opinion, it goes directly to how important our hobby is in the scheme of things and just how little funding is allocated to our activities. It also shows that there are contradictory sources of truth and not a single unified view on how to present this information to the global amateur community. In case you're wondering why that matters, electromagnetism doesn't stop at the political boundaries of the location where we might find ourselves and if that doesn't matter to you, consider again how you'd best talk to an amateur of any given DXCC entity and on what particular frequency you might achieve that. So, aside from whinging about it, what can you do about this? I have started a project, of course I have, that attempts to document two things, well, three. First of all I use the WIA version of the DXCC list - since the ARRL doesn't actually publish that for free anywhere - and use that to track a list of hopefully official frequency allocation documents. I'm also in the process of capturing the content of each of those documents into a database, so we can all figure out what the best frequency is to talk to another country. I'm still in the design stages for the database, for example, do we want to store a frequency in Hertz, in kHz, or pick a magnitude and store a number? Each of these choices has long term implications for using the tool. Then there's things like discovering which band plan applies to Scarborough Reef, the San Felix Islands and Pratas Island to name a few, since I've really only scratched the surface with the plans I've explored. I had visions of putting this on GitHub, but perhaps this should be part of the Wikipedia collection and it should live there. I'm still considering the best plan of attack. In the meantime, you can help. Please send an email to cq@vk6flab.com with the official band plan link for your own DXCC entity, and if you have thoughts on how best to structure the database or where this project should live, let me know. For example, should the database include just band plans, or should we also include things like modes. For example, the official VK calling frequency for 40m is 7.093 MHz. Should that be in the database and should we include the preferred Olivia calling frequency? While looking at that, consider the band labels we use. Australia doesn't have a 75m band, but others do. Some countries refer to the 4mm band, others refer to it by frequency. So, over to you. Let me know what you think. I'll leave you with a quote by Daren 2E0LXY: "It is not the class of licence the Amateur holds but the class of the Amateur that holds the licence." I'm Onno VK6FLAB

I am really excited to be speaking again with Dr Laura Driessen, who is now recognised as one of Australia's Superstars of STEM! You first met Laura 5 years ago back in 2018 when she was doing her PhD at the University of Manchester and Jodrell Bank. Laura's back story is all there in Astrophiz Episode 54. You heard about her obsession with space starting at age 4 and her natural yet meandering academic Astro journey up to the point where she was using commensal searches on the MeerKAT array in South Africa for pinpointing and localization of FRBs, Fast Radio Bursts. Today we're taking up that story from where we left off, and we hear of her first post-doc with the CSIRO in Perth, her FRB and Radio Star research and her outreach work in the outback with indigenous school kids who live near the iconic Murchison Widefield Array and the ASKAP Array. Laura tells us about her current research and her work as the joint Science lead on the VAST project and you will love the clarity of her description of the power and nature of Commensal Searches, and how she uses archival data to verify that her radio data is actually coming from her targeted star and not from a radio galaxy hiding behind it. Another gift Laura gives us is her brilliant explanation of how scientists establish and maintain collaborations both big and small, and how scientists often begin with a large number of hypotheses to explain observed phenomena and how the null hypothesis is such a powerful tool in developing an accurate understanding of our universe. On social media you'll find Laura, she's @AstroLauraD on Twitter. And her non-astro work can be found on Etsy at Oomigoomi ….. and her Whippet dog is astro.the.whippy on Instagram

We are splitting our content so one episode each month will be dedicated to a new guest interview, from the fields of radio astronomy, optical astronomy, space science or particle physics, Also each month you will get to hear from your regular presenter Dr Ian ‘Astroblog' Musgrave, who will preview a sky Guide for you for the coming month, and he will also take you on an astronomical journey of discovery in ‘Ian’s Tangent’. In our next interview-only episode, we talk with Clint Jeffrey, an amateur radio astronomer who works on the technologies for an 8,5metre dish constructed by the radio astronomy section of the astronomical society of Victoria in Australia. The dish is located in a quiet zone in a rural area about 130km north of Melbourne, and they have just achieved ‘First Light’ with a successful observation of the redshift of the Small Magellanic Cloud, and captured the galactic hydrogen inside the Milky Way.

Astronomers have discovered the biggest explosion we have ever seen. They spotted the remnants of this blast in the Ophiuchus galaxy cluster, most likely from a supermassive black hole using the Murchison Widefield Array and NASA's Chandra X-ray Observatory. The post Another Big Bang appeared first on Trekzone.

Stream episodes on demand from www.bitesz.com (mobile friendly) *New questions about dark matter and dark energy A new study is raising fresh questions about dark matter and dark energy -- two of the most mysterious and least understood features in the universe. A new hypothesis attempts to explain both the accelerating expansion of the universe and the movement of stars in galaxies without needing to draw on the concepts of dark matter and dark energy. *Murchison Widefield Array construction completes phase two The Murchison Widefield Array has reached a key milestone in its ongoing development, with the completion of its phase two expansion. The work which has taken nearly 16 months, includes 128 new antenna stations at the observatory site in outback Western Australia. *Is antimatter the hidden face of lightning Terrestrial Gamma Rays Flashes produced in lightning from thunderstorms can also generate antimatter. New research claims Terrestrial Gamma Rays Flashes react with the air to produce radioisotopes and positrons -- the antimatter counterpart of electrons. *Trojan Martian asteroids created by sunlight A new study claims some of the trojan asteroids orbiting with Mars could have been created by sunlight. While many of the Sun’s family of planets have trojans – Mars is the only terrestrial planet known to have trojans in stable orbits. *China 14th rocket launch for 2017 China’s busy rocket launch program is still in top gear with it 14th launch for 2017 blasting in to orbit. The latest mission – the third for the month -- involved a Long March 2C rocket flying from the Xichang Satellite Launch Center in southwestern China’s Sichuan province. *The Science Report Earth about to enter a mild La Nina weather pattern either in late December or early 2018. 40 per cent of adolescents with food allergies are experiencing frequent allergic reactions. Energy drinks linked to frequent dental problems. Air pollution linked to poorer quality sperm. Drinking coffee is more likely to benefit health than to harm it. For enhanced Show Notes including photos to accompany this episode, visit: http://www.bitesz.com/spacetimeshownotes Subscribe, rate and review SpaceTime at all good podcasting apps…including Apple Podcasts (formerly iTunes), Google Podcasts, Stitcher, PocketCasts, Podbean, Radio Public, Tunein Radio, google play, Spreaker etc Help support SpaceTime : The SpaceTime with Stuart Gary merchandise shop.

The study based on evidence of the iron 60 isotopes in meteorites indicate that a supernova shock wave is still the most-plausible origin story for explaining the short lived radioactive isotopes in our Solar System *A new window in the hunt for molecular signatures in deep space Astronomers have begun using one of the precursor radio telescopes for the Square Kilometre Array project to study molecular signatures which could lead to the detection of complex molecules that are precursors to life. The team are using the Murchison Widefield Array to undertake the observations focusing on the molecular gas and dust clouds from which new generations of stars are born. *New clues about superluminous supernovae Astronomers have detected an extraordinarily bright supernova in a surprising location. This supernova discovery challenges current ideas of how and where such super-charged supernovas occur. *Vega lofts two satellites on second launch this year An Arianespace Vega rocket has successfully launched two satellites into orbit. The mission blasted off into late night skies from the European Space Agency’s Kourou Space Port in French Guyana. *Western fears grow as Iran and North Korea conduct illegal missile tests Sanctions have been placed on both North Korea and Iran after the two rogue nations carried out new missile tests over the past few weeks. Most attention has focused on North Korea which has carried out numerous missile tests in recent months the other member of the so-called axis of evil – Iran -- has also continued its own missile program with a launch on July 27th in breach of United Nations security council resolution 2231. *The Science Report It may be too late to stop the planet heating up by two degrees, How drinking alcohol could improve your memory, A new expedition to an undersea continent east of Australia, New research into melanoma, How cats domesticated themselves – when they were ready. Subscribe, rate and review SpaceTime at all good podcasting apps…including iTunes, Google Podcasts, Stitcher, Pocketcasts, Podbean, Radio Public, TuneIn Radio, google play, etc. Email: SpaceTime@bitesz.com Join our mailing list at http://www.bitesz.com/join-our-mailing-list If you're enjoying SpaceTime, please help out by sharing and telling your friends.

Yay! Astrophiz 23 is out now on Soundcloud or subscribe in iTunes. Meet Asteroid Hunters Daniel Bamberger and Guy Wells. Astrophotographer Dr Ian ‘Astroblog’ Musgrave in ’What’s up Doc’ tells us what to look for in the night sky this week. Feature Interview: Daniel Bamberger & Guy Wells, who have set up the rapidly expanding and recognised Northolt Branch Observatory, explain how they image and verify orbits of asteroids and other NEOs. (Near earth Objects) Dr Nadezhda Cherbakov has been incommunicado, so we will have to wait for next week to look at the Hertzsprung-Russell Diagram “What”s Up in the Sky this Week” with Dr Musgrave: The planets of the morning sky, the evening sky and the Geminids meteor shower under a full moon. In the News: 1. The Low-Frequency Array (LOFAR), the antennas are receiving radio signals that have travelled billions of years to get here, from the depths of the cosmos. 

2. Another citizen science project turns up remarkable pulsar science via the einstein@home project. 3. Daniel Ung, a Masters student at Curtin University in Perth, Australia, has won the 2016 FEKO Student Competition, with implications for SKA and the MWA, the Murchison Widefield Array.

Astrophiz 22 is out now on Soundcloud or subscribe in iTunes Part II: The Parkes ‘Dish’ interrogates pulsars to expose gravity waves. We interview Operations Scientist John Sarkissian at the CSIRO Parkes Radio Observatory. He explains how the ‘Spider Dipoles’ that make up the Murchison Widefield Array in remote Western Australia contribute to SKA, how Parkes chase down gravity waves and has detected most of the world’s FRBs (fast radio bursts of unknown origin), after being distracted by ‘perytons’ and microwave ovens. And yes, ‘The Dish’ is searching for Extraterrestrial Intelligence in the international SETI ‘Breakthrough Listen’ project. We’re not saying they’re searching for Aliens ….. but Aliens! Dr Nadezhda in Part I of Stellar Evolution explains how the mass of a star determines its evolutionary path, and next week we will look at the Hetsprung-Russell Diagram “What”s Up in the Sky this Week” for Northern Hemisphere observers and astrophotographers, and for Southern Hemisphere Listeners, December is the best time to see the Large Magellanic Cloud and the Small Magellanic Cloud. We also expose Procyon and curse the moon for demolishing the Geminids Meteor Shower In the News: 1. The Spiderweb galaxy 
2. Imaging a Black Hole Event Horizon 
3. ICRAR tells us the Universe is slowly becoming less energetic (Well, who isn’t ;)

Astrophiz Podcast 1 is here for your listening pleasure. Astrophiz 101, interview with Robert Arrowsmith, History & Theory from Dr Nadezhda Cherbakov: James Clerk Maxwell. News about The Australian Compact Array and Murchison Widefield Array and what's in the night sky via Dr Ian Musgrave's Astroblog site, and reference to Adelaide Radio Astronomy Group. Thanks to Michael Roberts for the opening theme backing track

The National Geospatial-Intelligence Agency’s “Geointeresting” podcast welcomed Ms. Cleo Loi and Professor Steven Tingay to discuss the Murchison Widefield Array (MWA) — a radio telescope located in the Western Australian desert — and Loi’s discovery of the existence of tubular plasma structures in the inner layers of the magnetosphere surrounding the Earth. Professor Tingay is the director of the MWA project and Professor of Radio Astronomy at Curtin University in Australia. Loi is a PhD student in astrophysics at the University of Sydney. Tingay and Loi visted NGA's campus in Springfield, Virginia to speak with employees about the MWA and Loi's discovery. To learn more about Loi’s discovery, read the ARC Centre of Excellence for All-Sky Astrophysics press release (http://caastro.org/news/2015-tubes) and Dr. Tara Murphy’s article on The Conversation (http://tinyurl.com/pknq3e2).

The SKA will soon be the world's most sensitive radio telescope, able to view some of the most distant objects ever seen. In a special edition of Naked Astronomy this month, we follow Perth-based astronomer Kirsten Gottschalk on a visit to one of the two sites where it will be built, hundreds of kilometres from civilisation in the Western Australian outback. Kirsten also catches up with progress on the two precursor instruments - the Murchison Widefield Array and the Australian SKA Pathfinder - which are already being constructed on the site.
