China’s Tianwen-2 spacecraft has successfully arrived at Kamoʻoalewa—a tiny, enigmatic "quasi-satellite" that dances along with Earth on its trek around the Sun. A fascinating scientific debate is heating up over this object's true identity: is it a standard, heavily space-weathered asteroid, or is it a long-lost chunk of our own Moon, violently blasted into space by an ancient impact? Tianwen-2 is on a mission to solve this cosmic identity crisis, and it is happening right now. This week, we sit down with Andrew Jones, a contributing editor for The Planetary Society and a freelance space journalist covering China's rapidly accelerating lunar and planetary exploration programs. He takes us inside the mission to reveal how Tianwen-2 will attempt to hover and snatch samples from this mysterious world, what those pieces could teach us about our Solar System's history, and where China’s planetary ambitions are targeting next. Then, Chief Scientist Bruce Betts joins us for What’s Up to look ahead at asteroid missions and moments on the horizon through the end of this decade, from a Hayabusa2 flyby of asteroid Torifune next month to the 2029 close approach of asteroid Apophis.

https://www.youtube.com/watch?v=Cil0v7dIkgc Hosted by Tony Darnell. Streamed live on Jul 6, 2017. If we send humans to Mars, will they be able to survive? How hostile is the solar system for human exploration?   The Mars environment presents many challenges to human survival and long-term residence. In addition to radiation, unbreathable atmosphere, and dust storms, surviving alien microorganisms can present a health risk.   The US Congress has directed NASA to plan for a human mission to Mars. A critical element of the planning is to ensure the health and safety of astronauts travelling to, working on, and returning from the Red Planet.   Join Tony Darnell, Harley Thronson and Alberto Conti as they explore with Arnauld Nicogossian (George Mason University), Catharine A. Conley (NASA Planetary Protection Officer) and Charles Doarn (University of Cincinnati) the challenges of living and working on Mars.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Asteroids appear as moving points of light in an asteroid hunter's images so that when my Catalina Sky Survey teammate Alex Gibbs spotted a fuzzy moving object he immediately suspected it to be a comet. The data obtained by astronomers over the next 8 days enabled scientists at the Minor Planet Center to verify Alex's 31st comet discovery and give it the name C/2018 A6 (Gibbs). In January of 2018 it was in the constellation of Leo traveling from the vast empty space above the Sun's north pole toward the plane of the solar system which contains all of the planets and most of the asteroids. In March of 2018 Comet C/2018 A6 (Gibbs) will cross the plane of the solar system a bit farther from the Sun than the giant planet Jupiter's orbit. After that it will continue on a wide arcing parabolic path, pass under the Sun's south pole in the summer of 2019, and once again cross the plane of the solar system in February of 2021. After that it will continue into the vast empty space above the Sun's north pole from whence it came. How a comet brightens as it approaches the Sun is difficult to predict. With luck humans will be able to spot Comet C/2018 A6 (Gibbs) with their naked eye, binoculars, or a small telescope as it pays a rare visit to our planet's neighborhood.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From March 2026. Today's 2 topics: - My Catalina Sky Survey teammate Tracie Beuden was observing with our Schmidt telescope on Mt. Bigelow, Arizona in the constellation of Perseus when she found 2026-AA, the first asteroid of 2026. Asteroid hunters are trying to track Tracie's discovery with our number on it far enough in advance so humans could give it a tiny nudge and make it miss Earth.   - Humans can mitigate the damage done by the impact of an asteroid given a sufficient lead time. In 1998, the US Congress mandated NASA to detect and track 90% of the 1 km sized asteroids capable of effecting local mass destruction as well as global disruption of agriculture and other human activities. This goal has been accomplished. In 2005 Congress extended the mandate to require NASA to detect and track 90% of the 140-m asteroids capable of destroying a large metropolitan area.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

This weekend's Astronomy Daily wraps up the biggest stories from across the cosmos, starting with two completely fresh discoveries — a 1976 ocean rock that's turned out to hold atomic-scale proof of an ancient neutron star collision, and a record-breaking rocket launch from Europe's Ariane 6. Then we wind back through the week for our four biggest headlines: a new crew for Artemis III, JWST's salty 'Pink Planet' discovery, an update on the daring Swift Observatory rescue mission, and China's Tianwen-2 closing in on its target asteroid.   Story 1: A Kilonova's Fingerprint, Found in a 1976 Ocean Rock •       A rock sample dredged from the Pacific seafloor in 1976 has been found to contain a few hundred atoms of plutonium radioisotopes. •       The plutonium originated from a kilonova — a collision between two neutron stars — that occurred over 100 million years ago. •       Stellar debris from the merger settled to Earth and was slowly incorporated into a ferromanganese crust on the ocean floor. •       Isotope ratios provide the strongest physical clues yet to what created the elements and roughly when the merger occurred. •       Study published 18 June 2026.   Story 2: Ariane 6 Smashes Its Own Heaviest-Payload Record •       On 17 June 2026, an Ariane 64 rocket launched 36 Amazon Leo satellites from French Guiana (mission VA269 / LE-03). •       First flight of new P160C solid boosters — about a metre longer than the previous P120C, holding up to 156 tonnes of propellant each. •       Boosters deliver roughly a 10% performance increase, raising Ariane 64's LEO capacity to approximately 22 tonnes. •       The mission broke the 13-year record for heaviest payload ever launched by an Ariane rocket, previously held by the 2013 ATV 'Albert Einstein' resupply flight. •       Eighth Ariane 6 launch overall; 100th Amazon Leo satellite deployed by Arianespace.   Story 3: Artemis III Crew Revealed •       NASA announced the Artemis III crew on 9 June 2026 at Johnson Space Center: Commander Randy Bresnik, Pilot Luca Parmitano (ESA), and Mission Specialists Frank Rubio and Andre Douglas, with Bob Hines as backup. •       The Artemis II crew (Wiseman, Glover, Koch, Hansen) symbolically passed their lunar baton to the new crew. •       Artemis III is a two-week test flight in low Earth orbit to test docking procedures between Orion and commercial landers from SpaceX and Blue Origin. •       Targeted for launch as early as late 2027, ahead of a planned lunar surface landing in 2028. •       Will be Andre Douglas's first spaceflight.   Story 4: JWST Cracks the 'Pink Planet' Mystery •       JWST has confirmed salt clouds in the atmosphere of GJ504b, the 'Pink Planet,' located 57 light-years away. •       First direct evidence of salt clouds on a cold substellar companion object, a phenomenon theorised 15 years ago. •       At approximately 550°F, GJ504b is the coldest companion object ever directly imaged. •       Its true nature remains uncertain — it may be a giant planet or a brown dwarf. •       Research led by a Northwestern University team.   Story 5: The Swift Rescue Mission Heads for the Pacific •       NASA's Neil Gehrels Swift Observatory (orbiting since 2004) faces premature reentry due to orbital decay accelerated by recent solar activity. •       Katalyst Space Technologies' LINK robotic servicing spacecraft will attempt to grapple and boost Swift to a safer ~600km orbit. •       LINK launches on a Northrop Grumman Pegasus XL rocket, carried by Stargazer, the last flying Lockheed L-1011 TriStar. •       Stargazer departed NASA Wallops Flight Facility on 18 June 2026, en route to Kwajalein Atoll via California and Hawai'i. •       Launch targeted for 27 June 2026; if successful, it will be the first capture of an unprepared US government satellite by a commercial vehicle.   Story 6: Tianwen-2 Closes In on Kamo'oalewa •       China's Tianwen-2 spacecraft, launched May 2025, completed orbital insertion at near-Earth asteroid Kamo'oalewa on 7 June 2026. •       Amateur radio trackers in Germany detected fine ion-engine course-correction burns between 11–14 June 2026. •       Rendezvous and sample collection are expected around 4 July 2026. •       Kamo'oalewa is a 40–100 metre quasi-satellite of Earth; its origin (possibly a lunar fragment) remains scientifically debated. •       After sample return, Tianwen-2 will travel on to rendezvous with comet 311P/PanSTARRS in 2035.Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan who enjoy teaching astronomy classes and showing the public views through their telescopes. actualastronomy@gmail.com   This month we talk about the full range of telescopic magnification powers from Low, Medium to High and how to achieve them using exit pupil. Topics include using exit pupil as a guide to power and how to successfully use high powers.   To recap Exit Pupils and Eyepieces: We have High, Medium and Low powers, - Low Power is in the Exit Pupil Range 2-4mm, so on my 180mm f6 that's 12-24mm eyepieces giving 45x-90x - Medium Power is around 1.5mm Exit pupils, so a 9mm for my scope for 120x  - High equates to about a 0.5mm Exit pupil which for an F6 scope that would be a 3mm which on my 180mm would give 360x   In addition to these we have RFT or very low power for me I use my 40mm and 32mm for 27-35x and Ultra-high which is anything above 0.5mm. Careful in going to low as beyond 6-7mm exit pupils the pupil will cut into the light path.   The most favored eyepiece exit pupils are those in the 1.5-3mm range for galaxies, globular clusters. This is where the eye performs best under low light conditions and these magnifications help reduce the sky brightness without reducing the object brightness to the same extent,,,thus making such objects more visible. This is why I use my 17mm, 12.5, 12, 10mm's the most when making observations of these targets. For low power wide field nothing beats the 40mm XW which gives me a 2.5TFOV and 27x and I use my 5mm XW lots on the planets and Moon.   Shane do you have any high power eyepieces? What is the highest power you've successfully used? What are some of the challenges with using high powers?   My introduction to using high power came by accident. I wanted to buy all the Pentax XW's, while designed for spotting scopes, they work perfectly with eyeglasses and each year Pentax would put some on sale. The 20mm is arguable the dog of the lot, the 14mm is a bit better but the rest are of the highest quality so I ended up with these first but soon a after the 3.5mm went on sale and I thought…well…I'd eventually get it anyway so even if I didn't use it that much it'd be nice to have. Oddly I ended up using it all the time and it is one of my most used eyepieces and not only that but it barlows very well with my 1.6x Nikon creating a 2mm eyepiece.    Eventually I acquired the 5mm, 7mm and 10mm and use my 2x and 3x barlows on them. Typically you don't want to exceed the 0.5mm exit pupil size as on planets floaters and other eye issues challenge the observer. So why would I go above this threshold?   So wind the clock back to the Nova East Star party in 2003, Mars was at it's closest point to earth in 60,000 years and Tony Jones showed up late at night with his 5-inch Astrophysics APO refractor.  We ended up barlowing a 4.8mm Nagler 2x for 430x. The details were amazing. Roy Bishop, who has authored that section on Exit Pupils and Eyepieces for the OH was there, he explained that while no additional detail could be seen past about 300x making the image this large made the details that could be seen larger.   I've always enjoyed running high power on Mars and the 3.5mm on my 60mm Tak gives splendid views of Venus in the 100x range. With the 180mm f6 my 3.5mm gives 308x and on steady nights I have used up to 500x. After experimenting I determined the optimal magnification limit is about 430x and that coincides with the actual theoretical limits discussed in many texts and online posts.   I found that the Pentax 70-degree AFOV was a bit restrictive and wanted to use my 84-degree Docter. I ran across the SkyWatcher Nomad 5x Telecentric Barlow, Telecentrics don't move the exit pupil around and I have found sometimes SkyWatcher has a few hidden gems…it was only about $100EU and not available in NA so I thought I'd give it shot. It works perfectly, I get 432x and the field of view is excellent!   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Saturn's moon Titan is one of the most Earth-like worlds in our Solar System, with a dense nitrogen atmosphere, weather cycles, methane rivers, and vast organic dune fields. It also happens to be the perfect place to fly a drone. NASA's Dragonfly mission is doing exactly that, sending a car-sized, nuclear-powered rotorcraft to explore Titan's surface starting in 2034. With just two years until launch, the team is deep in the work of making it happen. This week, we're joined by two members of the Dragonfly team from the Johns Hopkins Applied Physics Laboratory. Felipe Ruiz is the mission's lead rotor engineer and mechanical implementation lead, responsible for designing the eight-rotor system that will carry Dragonfly across Titan's skies. Zibi Turtle is the mission's principal investigator, a planetary scientist whose career has spanned missions from Galileo to Cassini to Europa Clipper. Together, they walk us through the engineering challenges of flying a thousand-kilogram rotorcraft in an alien atmosphere, how the team is testing and validating the design here on Earth, and what the spacecraft's instruments will look for on Titan's surface. Then Bruce Betts, our chief scientist, joins us for What's Up, where we pay tribute to the Ingenuity Mars helicopter and the legacy of the first powered, controlled flight on another world.

Recently, Professor Avi Loeb was tasked by the White House, AARO, ODNI, and the FBI with assembling and leading a new UAP Science Advisory Council — comprising astrophysicists, AI experts, and psychologists — to advise the intelligence community on unidentified anomalous phenomena. It was announced the same week the government released its third batch of declassified UAP files. Now he joins us live to talk about what that actually means — and what it doesn't. This is not a "the aliens are here" stream. It's the harder conversation. I study the cosmic microwave background, and when we find an anomaly, we exhaust every instrument artifact and foreground before anyone whispers "new physics." I want to know why UAP science should run on a different evidentiary standard — and Loeb is exactly the right person to push on it, because he's already attributing much of the released footage to cosmic rays, balloons, and possibly Chinese drones, while holding the door open for the small fraction that stays unexplained. WHAT WE GET INTO: - The council, its mandate, and the question nobody's asking: does "advisory" mean anyone has to listen? - The orbs — Chinese surveillance drones, classified US tech, or something else — and the prior you'd need before you say "non-human" - Whether "absence of evidence is not evidence of absence" gets applied selectively - AI in the Galileo Project's detection pipeline, and the false-positive problem: what's the training comparison class for "non-human technology"? - The critique that a council built to study the object ignores where the data actually comes from — human witnesses GUEST: Professor Avi Loeb — Frank B.

Are we really ready? Hosted by Steve Nerlich. From Dec 1, 2025. Cheap Astronomy tries to stay sane on a trip to Mars? Dear Cheap Astronomy – Will we just go nuts on a two-year mission to Mars Well, we might if the space radiation doesn't kill us first. As we may have noted in previous episodes, current timelines for when we'll land on Mars seem to take little account of the fact that there are many mission components we don't even have conceptual solutions for let alone anything flight-tested or even prototyped. So current aspirations of having footprints on Mars in the 2030s are just aspirations.   Dear Cheap Astronomy – Will we just go nuts on a two-year mission to Mars, Part 2 In the last episode, we discussed the mental duress involved in sending a crew of up to five on a two year mission to Mars – which is 7 months each way with an extended stopover in the middle, with the whole experience involving relentless exposure to the risk of imminent death, and where radio delays with Earth may stretch out towards 20 minutes, enhancing the whole experience of isolation and helplessness.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

What did the ancient world discover about the cosmos? What were the contributions of Copernicus, Kepler, and Galileo? How did the science of astronomy advance under Newton? And how did everything change again with the discoveries of special relativity, general relativity, and quantum mechanics? With us to answer these questions is Sarah Alam Malik. Sarah is an expert on dark matter, and her work on large-scale experiments such as the Large Hadron Collider has placed her at the cutting edge of exploring the universe's mysteries and its fundamental laws. Today we discuss her new book entitled, A Brief History of the Universe (and our place in it).

In this episode of Talk Nerdy, Cara is joined by theoretical physicist, and associate professor of physics and astronomy, and core faculty in women's and gender studies at the University of New Hampshire, Dr. Chanda Prescod-Weinstein. They discuss her newest book, The Edge of Space-Time: Particles, Poetry, and the Cosmic Dream Boogie. Follow Chanda: @chanda
