EVSN - End-Permian Extinction Lasted 10X Longer on Land Than in Water
Release Date: 01/10/2025
Astronomy Cast Ep. 744: Lunar Time
The 365 Days of Astronomy
Streamed live on Feb 10, 2025. What time is it? OK, fine, what time is it on the Moon? The Moon orbits the Earth, so it doesn’t fall into a specific time zone. Also, there’s lower gravity on the surface of the Moon, which changes the rate that clocks tick. Well… It’s time to introduce Lunar Time. When are you when you are on the Moon? Researchers are putting together definitions! Hosted by: Fraser Cain and Dr. Pamela L. Gay SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

Travelers in the Night Eps. 301E & 302E: WOW! What a Ride & Dangerous Comet
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: From September 2024. - It's a good thing this one will miss Earth. Riding the surface of the asteroid that my Catalina Sky Survey teammate Richard Kowalski recently discovered would be an incredible experience. - Protection against a comet strike is worth considering. Every year, if we are lucky, several comets can come close enough for the Sun to warm and us to see the beautiful changing dust and gas...

EVSN - Craters in Northern Canada Offer Clues to Titan
The 365 Days of Astronomy
From June 17, 2021. New research presented at the Workshop on Terrestrial Analogs for Planetary Exploration used the Haughton impact crater in Arctic Canada as a potential analog for impact craters on Titan, one of the targets of the upcoming Dragonfly mission. Plus, giant spinning structures, the slowing of the Milky Way, a blinking star, and volcanoes here on Earth.

Awesome Astronomy - Farewell NASA's InSight Mission
The 365 Days of Astronomy
Ralph Wilkins hosts. Damien Phillips, John Wildridge and Dustin Ruoff produce. From Dec 30, 2022. We say farewell to NASA's Insight mission on Mars. This lander spent 6 years on the Martian surface examining the interior of the planet. It discovered that Mars is not geologically dead as we previously thought. It discovered that Mars has a larger core than we thought, its magnetic field was stronger than we thought and the crust is thinner. And in typical NASA fashion, it made us all sad to think of the little fella dying in the cold Martian dirt. The heartless swines! All videos...

Cheap Astronomy - Dear CA #115: The Next Steps
The 365 Days of Astronomy
Two steps (at least). Hosted by Steve Nerlich. From June 25, 2024. Dear Cheap Astronomy – So what can you do with lunar regolith? Lunar regolith is readily available for use by space explorers, but just being available doesn’t mean it’s going to be useful. Nonetheless, there have been some interesting suggestions about what to do with it over the years since Apollo and now that we are in the Artemis era, this seems a good time to blow the moon-dust off some of those suggestions. Dear Cheap Astronomy – Are we really not going to Mars in the 2030s? Well, probably not. NASA’s...

Exoplanet Radio - Ep. 33: What is the Habitable Worlds Observatory?
The 365 Days of Astronomy
Hosted by Tony Darnell. From September 8, 2023. There’s no question that humanity is making fast progress in understanding, cataloging and classifying planets around other stars. So far we’ve found over five thousand five hundred of them. But let’s face it, we really want to know, maybe more than anything else, whether these planets have any life on them and whether they are habitable for us to, maybe, live on. Finding habitable worlds has been a driving passion since we first learned there were other planets out there, and to find them, we are going to need a dedicated instrument...

Astronomy Cast Ep. 743: What Else Can We Learn From Gravitational Waves?
The 365 Days of Astronomy
Streamed live on Feb 3, 2025. Just a few years ago LIGO detected the first direct evidence of gravitational waves coming from colliding black holes. And there you have it. Boom! Black holes collide! But that wasn’t all we learned from gravitational waves, nor will we learn. Sure, the masses of merging black holes are nice to know, but what else can we learn from gravitational black holes?

Travelers in the Night Eps. 299 & 300: Caves of Mars & Lost and Found
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: - Aug 27, 2024. Presently the surface of Mars is very dry and any liquid water that reaches it quickly boils away since the martian atmospheric pressure is what you could experience in your space suit 30 to 50 miles above the Earth's surface. However, since the martian gravity is about 1/3 that of the Earth, its crust is less dense and more porous than what we find on our home planet. - Sep 3, 2024....

NOIR Lab - 25 Years of the Gemini International Observatory
The 365 Days of Astronomy
The Gemini International Observatory consists of two 8.1 meter telescopes located in Hawai’i and Chile. These telescopes have been at the cutting edge of astronomy research since their inception. Gemini Observatory is currently celebrating its 25th anniversary. This podcast takes a look at the first 25 years of Gemini Observatory and looks ahead to the future. Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

info_outlineFrom April 27, 2021.
The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.
