Astronomy Cast Ep. 235: Einstein
The 365 Days of Astronomy
From October 17, 2011. What can we say about Einstein? Albert! Freaking! Einstein! Lots, actually. In this show we’re going to talk about the most revolutionary physicist… ever. He completely changed our understanding of time, and space, and energy, and gravity. He made predictions about the nature of the Universe that we’re still testing out.

Travelers in the Night Eps. 805 & 806: Very Close Miss & Distant PHA
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. From July, 2024. Today's 2 topics: - During a recent 60 day period asteroid hunters observed 23 asteroids which came closer to us than our Moon. Six of them passed closer to the Earth’s surface than 22,236 miles which is the distance to our communication satellites. - It is hard to obtain time on the 8m Gemini South Observatory telescope on Cerro Pachon in Chile and the Large Binocular Telescope with its twin 8m...

Astro Interviews - Fraser Cain
The 365 Days of Astronomy
From August 19, 2017. Your audio editor, Richard Drumm, interviewed Astronomy Cast’s co host Fraser Cain. The idea was to interview him before and after the total solar eclipse that was upcoming, and get his before and after impression of the event. Unfortunately the clouds at Carbondale, Illinois, had other plans. Fraser & Pamela were at SIUC’s Stadium and Richard was 2 miles away at the SIUC School of Agricultural Sciences. Richard had a clear sky and Fraser & Pamela did not. This unfortunate turn of events blew the interview’s main purpose to bits, so to speak. Even so, the...

EVSN - Saturn’s Rings Are Made of a Broken-up Moon
The 365 Days of Astronomy
From September 16, 2022. Using computer simulations, researchers have pieced together a possible scenario where Titan caused another of Saturn’s moons to break up and become the beautiful ring system we see today. Plus, organic molecules on Mars, the death of the dinosaurs, and a review of Lightyear on Disney+.

Space Stories - When Stars Explode: From Nova to Kilonova
The 365 Days of Astronomy
Hosted by Avivah Yamani, your Director. What happens when a star dies? Today we journey through the powerful stellar finales, from the gentle flare of a nova to the cataclysmic force of a kilonova. Join us as we unravel the stories behind novae, supernovae, hypernovae, kilonovae, and the recently discovered micronovae. Have a listen & find out what makes stars go out with a bang!

Deep Astronomy - The Earth As An Exoplanet
The 365 Days of Astronomy
Hosted by Tony Darnell. From August 22, 2018. Are we alone? How unique is our Earth? Should the hunt for life beyond Earth uncover a multitude of habitable worlds and few (if any) inhabited ones, humanity would begin to understand just how lonely and fragile our situation is. On the other hand, if our hunt yields a true diversity of inhabited worlds, then we would learn something fundamental about the commonality of life in the cosmos. Like this content?

Astronomy Cast Ep. 10: Measuring Distance in the Universe
The 365 Days of Astronomy
From November 13, 2006. You hear distances all the time in astronomy. This star is 10 light-years away; that galaxy is 50 million light-years away; that Big Bang over there happened 13.7 billion years ago. But how did astronomers actually figure out how far away everything is? It’s not a single measuring stick. Instead, astronomers have built up a series of overlapping measuring tools (yes, we’re calling supernovae and variable stars “tools”), which take us from right around the corner to very ends of the Universe. Get out your ruler… no, the bigger one… never mind… just listen....

Travelers in the Night Eps. 803 & 804: Monster NEO & Tracie’s Solo
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. From June & July 2024. Today's 2 topics: - Since larger space rocks are rare, it was surprising when my Catalina Sky Survey teammate Hannes Groller found a half mile diameter asteroid traveling through the constellation of Auriga. Fortunately on it’s current path 2024 JW1 can’t come closer than 53 lunar distances from us. Asteroid hunters will continue to track 2024 JW1 to make sure that it does not become a threat...
info_outlineFrom December 3, 2021.
A Mars-sized planet was found just 31 light-years away, orbiting its star every eight hours and having 55 percent the mass of the Earth, leading scientists to conclude it’s mostly made of an iron-nickel core. Plus, water on Earth, a huge comet, and a review of a Canon lens.
