Podcasts about meteorites

The mystery of Tabby's star began to unfold when in 2015 Dr. Tabetha S. Boyajian [boy-AA-jee-uhn] of Louisiana State University and her team published a paper describing the irregular dips in the light output of what otherwise would seem to be a garden variety star over the period 2009 to 2013. Subsequently a list of proposed explanations include swarms of comets, large asteroids, a debris disk, and even a massive alien megastructure.

Data are consistent with the hypothesis that the planet K2-18b is a Hycean planet with a warm liquid water ocean teaming with life and a thin hydrogen rich atmosphere containing methane and other molecules containing carbon. Scientists in an opposing camp point out what we might be observing is a rocky world with a hot life killing atmosphere.

Australia's music industry is worth more than $8 billion annually. However competition is fierce. After arriving as a refugee, Baraka the Kid has overcome the odds to make a name worldwide.

When we find a planet which appears to have the chemical signs of living organisms in its atmosphere, the desire to take a close up look at it will be hard to contain. In a Scientific American article, Lee Billings describes Yuri Milner's 100 million dollar project "Breakthrough Starshot" which has been created to leap frog our current rocket technology's extremely long travel times to nearby planets. The plan is to put ultra light space probes on paths which will enable them to collect data as they streak by nearby potentially habitable planets. Our current iPhone technology is being used to envision a tiny robotic space probe which features cameras, life detecting sensors, maneuvering rockets, computers, and communications gear and yet has a mass of about that of a dime. Photons from 100 gigawatt pulses from a ground based laser array are then envisioned to reflect off the tiny spacecrafts solar sail where they transfer momentum to the space craft accelerating it to 20% of the speed of light. Numbers of these tiny robotic investigators could be launched together into Earth orbit and perhaps one a day could be sent towards a nearby star accelerated by laser pulses each of which contains the energy required to send a space shuttle into orbit. In a few decades closeup views and data from nearby worlds would begin streaming back towards the residents of our planet. The cost of investigating our planetary life hosting neighbors is likely to be less than what the US is planning to spend upgrading its nuclear weapons.

In the search for life on Mars, Europa, Titan, and elsewhere in the universe astro-biologists are scouring the Earth for creatures tough enough to flourish under really difficult conditions. So far the leading species are the Tardigrades commonly known as water bears or moss piglets.

What will life be like on other planets? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice explore the origins of life on alien planets and extremophiles right here on Earth with astrobiologist Kennda Lynch. (Originally Aired February 22, 2022)NOTE: StarTalk+ Patrons can watch or listen to this entire episode commercial-free here: https://www.startalkradio.net/show/alien-worlds-and-extremophiles-with-kennda-lynch/Thanks to our Patrons Alex Chadwick, Eric Gross, Tamara Michael, Gerald Johnson, Jordan Shelley, Brendan Barbieri, David Bell, Costa Cad Creations, Tim Costella, and Adam Baker for supporting us this week.Photo Credit: Sharanbhurke, CC BY-SA 4.0, via Wikimedia Commons Subscribe to SiriusXM Podcasts+ to listen to new episodes of StarTalk Radio ad-free and a whole week early.Start a free trial now on Apple Podcasts or by visiting siriusxm.com/podcastsplus.

Recently Dr. Yossi Shvartzvald led a team which published their discovery of an Earth sized planet using microlensing in the Astrophysical Journal Letters. The newly discovered planet OGLE-2016-BLG-1195Lb orbits a small dim object about 13,000 light years from us. With only 7.8% of the Sun's mass the new planet's star may be a brown dwarf and not a star at all. At about the same distance from its star as we are from the Sun this new planet is likely to be an ice ball world colder than Pluto.

"I don't believe in any nonsense... but I'll keep an open mind. Out here, who knows?"In July of 1970, an Athena RTV rocket was launched from Green River, Utah. Containing the radioactive element cobalt-57, the rocket was supposed to arc harmlessly down in White Sands, New Mexico. But instead it went rogue, streaking south over the Mexican border to a desolate area near the Durango-Chihuahua state line.This location, known by many as the "Zone of Silence," has long held a reputation for the unexplained. Dating back to the 1800s, local homesteaders have claimed to witness "hot pebbles" tumbling from the sky. Planes have crashed here, meteorites fall with surprising regularity, and walkie-talkies reportedly malfunction within this sprawling desert.

Microcosmos Records is pleased to present Phobos by EDD-989. EDD-989 is a project by Eduard Korkin from St.Petersburg, Russia. Eduard has been in love with music since childhood, he started his musical journey playing with analog electronic sound. Then, he tried various music styles, and in 2011 he began producing psychedelic chillout. In 2018, after the release of his first album, he acquired the status of a recognizable artist in space ambient and chillout. Phobos is notable for the density of its sound. When listening to it, it feels like being enveloped in a soft cozy blanket. Analog synthesizers and acoustic percussion create warm and vast soundscapes. The theme of the Space, which is traditional for EDD-989, develops finely in the album: the Space here is a natural environment for the listener to feel confident and calm. Distant stars, meteorites, planets, and satellites are painted with rich sound colors, in a friendly manner they invite the listener to join a joyful and breathtaking cosmic round dance. Turn on Phobos, immerse yourself in soft sound waves, and set out on a relaxing interstellar journey on a comfortable spaceship with the captain of EDD-989 and the Microcosmos Records team.

When I discovered 2014 JO25 with the NASA funded Catalina Sky Survey's 60 inch telescope on May 5, 2014, it appeared as a single point of light as it moved past us. As 2014 JO25 approached the Earth from the direction of the Sun in 2017, no-one had any idea that it is really a double asteroid system nearly a mile in diameter.

Since there is a world wide market for meteorites some of which can be sold for millions of dollars, on line, the question of ownership becomes important. 

Spider-Man Team-Up #7 (1997)Look, I know it's supposed to be more Thunderbolts but the “Justice Like Lightning” trade tricks you into reading a Spider-Man book. Thankfully, it is chronologically congruent to the ongoing storyline that we are covering so let's keep going.Spider-Man is framed for murder and the Thunderbolts are the only ones to can help (because everyone else is dead). Songbird and Mach-1 brawl with the web-slinger while Atlas signs a rooftop autograph using his fingernails. It is ultimately revealed the Enclave (aka Wilford Brimley and the Egon Spanglers) are sending androids out to muck up the works and that really steams Mach-1's ponytail.Also, Spider-Man hits a brick wall, Stan Lee makes Batman obese, Techno goes full Dolby and Mary Jane's course books are just too damn EXPENSIVE!All this plus Jen and Shawn share their experience at the latest RetroMania and talk about the new, bizarre Superman movie toys.*** PROPER COMIC BOOK DISCUSSION STARTS AT 00:12:30 ***Promos: 8TW AUDIO WORKS (https://twotruefreaks.com/podcast/8tw-promo-pilot-season/)Continue the conversation with Shawn and Jen on Twitter / Instagram / Facebook / Threads / Bluesky or email the show at worstcollectionever@gmail.comAlso, get hip to all of our episodes on YouTube in its own playlist! https://bit.ly/WorstCollectionEverYTDownload the podcast on Spotify, Apple Podcasts and wherever you get your favorite shows.

When a fleet of interstellar spaceships leaves our solar system for a planet circling a nearby star the most important of all of the riches that human explorers will carry with them will be libraries of our planet's DNA and the seeds of plants. They are the connection between past life, the inorganic world, and future life.

NASA's Europa Clipper was launched October 14, 2024 on a mission to conduct a detailed study of Jupiter's Moon Europa.  The space craft will travel some 1.8 billion miles and should reach Jupiter in April 2030.  This mission will begin to tell us if life as we know it can occur relatively close to home.

Thunderbolts #2 (1997)Our OG Thunderbolts discussion continues as the Thunderbolts adjust to their newly heroic personas in a battle against the Mad Thinker and his plan to suck knowledge out of Franklin Richards's brain. Thankfully, the T-Bolts are here to handle the situation even though they pretty much get their asses handed to them by Thinker's Gumby-looking android.Also, Mach-1 gets amorous, Citizen V tells a joke and the mayor of NYC strong-arms a grieving child into allowing the T-Bolts to inhabit the home of his deceased family.All this plus Shawn talks about the DEATH OF SUPERMAN and Jen expresses her frustration with BATMAN: H2SH!*** PROPER COMIC BOOK DISCUSSION STARTS AT 00:15:03 ***Promo: MARVEL STAR WARS: FROM EMPIRE TO JEDI (https://fireandwaterpodcast.com/show/empiretojedi/)Continue the conversation with Shawn and Jen on Twitter / Instagram / Facebook / Threads / Bluesky or email the show at worstcollectionever@gmail.comAlso, get hip to all of our episodes on YouTube in its own playlist! https://bit.ly/WorstCollectionEverYTDownload the podcast on Spotify, Apple Podcasts and wherever you get your favorite shows.

With more than 70% of its surface covered in water, Earth is rightly known as the "blue planet". But where did this water - so essential to life - originate? While some theories suggest that hydrogen was delivered to Earth from space via asteroids, new research indicates that the building blocks for water may have been present on our planet all along. We chat to Tom Barrett from Oxford's Department of Earth Sciences to find out more.

The NASA Kepler Spacecraft has discovered more than 2,000 planets which have been confirmed to be orbiting distant stars. It performs this remarkable feat by imaging more than 145,000 stars simultaneously to observe and measure the tiny dips in light which occur as a planet passes in front of its star. Astronomers have long known that many of the solar systems in the Milky Way have more than one star. To investigate the possibilities for life in a double star system, Dr Max Popp a scholar at Princeton University and Dr. Siegfried Eggl of Germany's Max Plank Institute substituted the real giant planet orbiting the stellar pair Kepler 35A and B with an Earth sized one orbiting the Kepler AB pair with periods between 341 and 380 days. Their detailed analysis is published in the journal Nature Communications.

À l'occasion de la Journée mondiale des espèces menacées, le 11 mai, BSG rediffuse cette série consacrées aux 5 grandes extinctions de masse connues par la Terre.Suite de la présentation de chacune des 5 grandes extinctions de masse. De fait il n'y en a pas que 5, il y en a eu beaucoup plus dans l'histoire de la vie. Mais il y en a 5 majeures, qui ont éradiqué en peu de temps, sur toute la planète, plus de 75% des espèces, parfois 95% dans les océans et ou sur la terre ferme.La 5e et dernière extinction de masse s'est produite il y 66 millions d'années. C'est l'extinction Crétacé-Paléogène. Elle entraîne la disparition de la majeure partie des espèces terrestres (dont les dinosaures), et de 3/4 des espèces marines. Les causes ne sont pas claires. Mais le champ est libre pour les mammifères ! D'où viennent-ils ?Contrairement à la plupart des amphibiens, les amniotes ont pu s'affranchir de pondre dans l'eau grâce à l'amnios, un sac qui protège l'embryon de la déshydratation. Les premiers amniotes sont connus dès -312 Ma, c'est-à-dire au milieu du Carbonifère (l'ère des fougères géantes qui a produit le charbon).Les mammifères sont des synapsides, l'un des deux groupes d'amniotes. Les autres sont les sauropsides, qui comprend les reptiles, les oiseaux et leurs parents disparus. Les synapsides, les sauropsides et les amphibiens (non-amniotes) constituent les tétrapodes.Les premiers synapsidés et les sauropsidés ressemblaient à des petits lézards. Les synapsides sont devenus de plus en plus mammifères et de moins en moins reptiliens. Une caractéristique commune aux synapsides est la fenêtre temporale, un trou dans le crâne situé derrière les yeux, destiné à réduire le poids de ce crâne.Les synapsides modernes sont tous à sang chaud, mais beaucoup de leurs ancêtres étaient à sang froid. On ignore à quel stade les synapsides ont évolué vers la pilosité et les glandes mammaires. Une autre innovation évolutive des synapsides ont été les premières dents différenciées.Sylvie Crasquin est paléontologue, spécialiste des microfossiles, et aussi des extinctions de masse. _______ 

On March 3, 2024 my Catalina Sky Survey teammate Kacper Wierzchos was asteroid hunting with our 60 inch telescope on Mt. Lemmon, Arizona when he spotted a fuzzy object in the constellation of Draco.  After Kacper reported his discovery to the Minor Planet Center, observers in Arizona, New Mexico, and Tenerife confirmed it to be a comet and it was given the name C/2024 E1 (Wierzchos).  Kacper's discovery has a hyperbolic orbit indicating that after coming slightly closer to the Sun than the planet  Venus on January 21, 2026 it will be ejected from the solar system never to return.

Thunderbolts #1 (1997)It's time to talk about the origins of the MCU's latest offering as we look at the very first issue of the THUNDERBOLTS!Of course, there is the big undercover villain twist at the end here but who can blame them when Onslaught eliminated all of our heroes and all that's left is Spider-Man, Daredevil and (maybe) Blade. We got Baron Zemo masquerading as a capoeira-slinging Homelander, Techno smuggling in his contraband robot bartenders and so many free-floating goatees you'll think you're trapped in a cable-ready erotic thriller.Also, Meteorite gets judgy, NYC ladies get thirsty of Atlas and Black Widow shows up dressed like she's late for work at a print publishing firm.All this plus Jen and Shawn cover some recent purchases from Free Comic Book Day.*** PROPER COMIC BOOK DISCUSSION STARTS AT 00:11:51 ***Promos: CELLULOID HEROES (https://open.spotify.com/show/5G4VxlMzO0yy7Rub7MPUzx?si=851e84cb62b24949)Continue the conversation with Shawn and Jen on Twitter / Instagram / Facebook / Threads / Bluesky or email the show at worstcollectionever@gmail.comAlso, get hip to all of our episodes on YouTube in its own playlist! https://bit.ly/WorstCollectionEverYTDownload the podcast on Spotify, Apple Podcasts and wherever you get your favorite shows.

On May 5, 2014 when I discovered 2014 JO25 with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona it was the brightest, fastest asteroid I had ever seen. In April of 2017, 2014 JO25 returned to come within 1.1 million miles of us at 21 mi/s. This rare, very close approach by an asteroid, of 2014 JO25's size allowed scientists at NASA's Goldstone Solar System Radar in California and the National Science Foundation's Arecibo Observatory in Puerto Rico to obtain radar images of it. Amazingly these images showed that what we had observed as a solitary moving point of light and had assumed to be a single asteroid is actually two asteroids in contact with each other. This tight pair rotates about a common center of gravity about every 5 hours which in turn orbits the Sun in about three years. 41 days before its encounter with Earth, this tight pair was closer to the Sun than the planet Mercury.

This week, we're rival telescopes trying to be the first to find the elusive ninth planet (gutted, Pluto). Highlights include: - We're searching for massive Assteroids... - Asteroids hate to be lonely... - Target shit, get banged... - Research the D! - Ooh, that's a nice Mitch... - Space Cluedo! - There's a lot of suspicious gas clouds in this part of space... - Comets can't be everywhere! - Meteorites aren't even a thing...

My Catalina Sky Survey teammate Hannes Gröller was asteroid hunting in the constellation of Ursa Major with the University of Arizona 90 inch Bok telescope on Kitt Peak when he discovered a faint moving object surrounded by a tiny gas and dust cloud called a coma. May 19, 2028 comet C/2025 D1  (Groeller) reaches its closest point to the Sun some 14.1 times the Earth-Sun distance and thus sets the record for the comet which stays furtherest from the Sun.After rounding the Sun comet C/2025 D1 (Groeller) will head back into truly deep space perhaps never to return.

Using the University of Arizona's Large Binocular Telescope atop Mt. Graham in southern Arizona, Dr. Paul Wiegert of Western University in Canada, led a team of astronomers who have determined that a 2 mile diameter object bucks the solar system traffic by traveling in a direction backwards to all of the planets. In their March 30, 2017 article in the journal Nature, these astronomers confirm that 2015 BZ509, travels about Jupiter on a path in a direction opposite to nearly every other member of our solar system. Amazingly it has avoided a collision with Jupiter by using the giant planet's gravity to maintain a path that has been stable for a million years or so. This astounding trick is performed as 2015 BZ509 passes once inside and once outside of Jupiter's orbit as they both travel about the Sun. The resulting effect of Jupiter's timely gravitational pulls on this small asteroid are exactly right to keep it from having a collision or from being ejected from the solar system.

In this episode of SpaceTime, we unveil groundbreaking evidence that challenges previously held theories about the origins of Earth's water. Recent findings published in the journal Icarus indicate that rather than being delivered by asteroids and comets, Earth's water may have formed alongside the planet itself. The study utilizes a unique meteorite known as the enstatite chondrite to reveal a rich source of hydrogen essential for water formation, reshaping our understanding of how life-sustaining conditions developed on Earth.The Enigmatic Magnetic Field of MarsNext, we delve into the curious case of Mars's magnetic field, which has puzzled scientists for decades. A new study suggests that the strange magnetic signatures observed on the Red Planet could be attributed to a partially molten core predominantly covering the southern hemisphere. This research provides fresh insights into Mars's geological history and the implications for its atmospheric evolution, as the planet transitioned from a warm, wet environment to the arid desert we see today.The Lyrids Meteor ShowerAdditionally, we celebrate one of humanity's oldest known meteor showers, the Lyrids, which are currently dazzling skywatchers. First recorded over 2,700 years ago, these meteors originate from comet Thatcher and promise a beautiful celestial display. Although not as prolific as other meteor showers, the Lyrids offer a captivating spectacle for stargazers, with expectations of 10 to 15 meteors per hour during peak viewing times.00:00 Space Time Series 28 Episode 50 for broadcast on 25 April 202500:49 New evidence on the origins of Earth's water06:30 Analysis of the enstatite chondrite meteorite12:15 The mystery of Mars's magnetic field18:00 Implications of a partially molten Martian core22:45 Overview of the Lyrids meteor shower27:00 Summary of recent astronomical findings30:15 Science report: Health risks linked to food additiveswww.spacetimewithstuartgary.comwww.bitesz.com

One little known and infrequently observed phenomenon in the natural night sky are “bright nights” during which observers have reported being able to read a book  when both the Sun and Moon are both well below the horizon.  

My Catalina Sky Survey teammate Greg Leonard was observing with our team's 60 inch telescope on Mt. Lemmon in Arizona when he discovered a relatively large space rock, 2017 FD157, which can theoretically come closer to the Earth's surface than the communications satellites. We don't have enough data to predict when it will make a very close approach to us. What we do know is that 2017 FD157's orbit and that of the Earth nearly intersect coming to about Earth diameter of each other. For 2017 FD157 to make a very close approach to our planet, both of them would need to be at the position on their respective paths which are closest to each other. If history is a guide, it is likely that additional observations will reveal that 2017 FD157 will never impact the Earth. About once every 11,000 years one of its size impacts the Earth with an atmospheric impact energy of several of large hydrogen bombs creating a crater a mile in diameter. If in an extremely unlikely turn of events, 2017 FD157, appears likely to impact our planet in the far distant future, humanity would be well served to mount a space mission to deflect it from it's deadly course. If humans have enough time they may be able to paint it so that over time sunlight pressure would change its path otherwise a nuclear detonation or some other more aggressive move would be necessary.

On a single February night my Catalina Sky Survey teammate Jacqui Fazekas reported  the discovery of 5 Earth approaching objects using our small but mighty Schmidt telescope on Mt. Bigelow, Arizona.Rest assured that on any given night there are asteroid hunters on the look out for seriously dangerous space rocks.

Asteroid hunters have become aware of the many small space rocks which come near Earth because of improvements made to telescopes, cameras, and computer analysis software. Recently, my Catalina Sky Survey teammate Rose Matheny used her skills and a new camera to discover the second small space rock in 32 days which came between the communications satellites and the Earth's surface. Rose spotted her 10 to 12 foot diameter space rock as it approached the Earth more than a million miles away with its little full moon face pointing towards us. 31 hours later, her discovery, 2017 GM, came to within 10,100 miles of Earth as it streaked by at about 11 mi/s on its way towards an encounter with Venus five and a half weeks later. It it had been on an impact trajectory with our planet, Rose's early detection would have allowed asteroid hunters to alert humans to prepare for a spectacular light show as it exploded in our atmosphere.

As the Earth travels in its orbit around the Sun it collides with objects called meteoroids traveling through space.  These tiny members of the solar system range in size from dust grains to objects a meter in diameter.By becoming part of the GMN's network , your data will help to discover and document meteor showers, aid in identifying the parent cometary objects, and in some cases help to identify locations to search for meteorites. 

In 2013 a 56 foot diameter space rock exploded over Chelyabinsk, Russia releasing the energy of 450 kt of TNT and filled local hospitals with some of the 1,500 people who were injured. Fortunately no one died. In 1908 a 200 ft diameter meteor exploded over a largely unpopulated region at Tunguska, Siberia knocking down trees over a 750 square mile area. If it had hit over a populated area it could have caused a million casualties. The approximately 250 people in the USA that NASA has working on asteroid detection and ways of mitigating the effects of an asteroid impact have plenty to do. We still have to locate and track about a hundred very large asteroids which could produce global climate change. Further, there are approximately 14,500 undiscovered slightly smaller ones which could cause a hurricane sized footprint damage areas to land areas on our planet. Fortunately it is extremely unlikely that any but one of the smallest space rocks will hit the Earth in the next 100 years.

Meteorite falls are extremely rare and offer a glimpse of the processes that formed our world billions of years ago.

On 27 December 2024 the Atlas group in Chile discovered an object now known as 2024 YR4 which appeared to have a significant chance of impacting Earth 22 December of 2032. The most recent data indicates the chance that 2024 YR4 impact Earth is about 1 in 25,000.  These data indicate our moon has about a 1 in 700 chance to be impacted by this space rock. Even so astronomers are preparing for 2028 when 2024 YR4 willagain come within the range of our instruments.   Current data indicates 2024 YR4 will miss the Moon by less than 1000 miles on  2032 December 22 giving astronauts there a Merry Christmas.

PLANETARY DEFENSE GAINING VERA RUBIN OBSERVATORY IN CHILE AND NEO SURVEYOR IN ORBIT: 1/4: Impact: How Rocks from Space Led to Life, Culture, and Donkey Kong Hardcover – by  Greg Brennecka  (Author) https://www.amazon.com/Impact-Rocks-Space-Culture-Donkey/dp/0063078929/ref=tmm_hrd_swatch_0?_encoding=UTF8&qid=&sr= Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth's early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet. While meteorites have provided the raw materials for life to thrive, they have radically devastated life as well, most famously killing off the dinosaurs and paving the way for humans to evolve to where we are today. As noted meteoriticist Greg Brennecka explains, meteorites did not just set us on the path to becoming human, they helped direct the development of human culture. Meteorites have influenced humanity since the start of civilization. Over the centuries, meteorite falls and other cosmic cinema have started (and stopped) wars, terrified millions, and inspired religions throughout the world. 1957

PLANETARY DEFENSE GAINING VERA RUBIN OBSERVATORY IN CHILE AND NEO SURVEYOR IN ORBIT: 2/4: Impact: How Rocks from Space Led to Life, Culture, and Donkey Kong Hardcover – by  Greg Brennecka  (Author) https://www.amazon.com/Impact-Rocks-Space-Culture-Donkey/dp/0063078929/ref=tmm_hrd_swatch_0?_encoding=UTF8&qid=&sr= Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth's early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet. While meteorites have provided the raw materials for life to thrive, they have radically devastated life as well, most famously killing off the dinosaurs and paving the way for humans to evolve to where we are today. As noted meteoriticist Greg Brennecka explains, meteorites did not just set us on the path to becoming human, they helped direct the development of human culture.
