The 365 Days of Astronomy

Hosted by Rob Sparks. The 10-year Legacy Survey of Space and Time has officially started, marking the beginning of a new era in astronomy and astrophysics. Over the next ten years, Rubin will relentlessly observe the entire southern sky every few nights to create an ultra-wide, ultra-high-definition time-lapse record of our Universe. This long-awaited milestone is the culmination of years of effort by thousands of people around the world. In this podcast, Dr. Christina Williams and Dr. Yumi Choi describe the LSST and its science goals as well as what they are most excited about researching...

The 365 Days of Astronomy

From July 15, 2026. Hosted by: Dr. Pamela L. Gay () Our solar system readily provides us with free samples of other worlds in the form of meteorites. The trick comes in first recognizing them, and then in understanding what science is locked in their minerals. One major center for collecting and studying these space rocks is Arizona State University's Buseck Center for Meteorite Studies which houses the Carleton B. Moore Meteorite Collection. Join us as we discuss the collection with Director Rhonda Stroud.   We've added a new way to donate to 365 Days of Astronomy to support editing,...

The 365 Days of Astronomy

Hosted by: Fraser Cain () and Dr. Pamela L. Gay () From April 21, 2008. Our senses can only detect a fraction of the phenomena happening in the Universe. That’s why scientists and engineers develop detectors, to let us see radiation and particles that we could never detect with our eyes and ears. This week we’ll go through them all, so you can understand how we see what we can’t see.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

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 November 2025. Today's 2 topics: - Throughout history small close approaching space rocks have been a part of our environment. Now, thanks to improved telescopes and cameras, asteroid hunters are routinely discovering these small asteroids as they pass closer than the Moon is to us. Since these tiny asteroids are only bright enough to detect for a few days out of their long, many month duration paths about the Sun,...

Hosted by Avivah Yamani, our Director! Was Betelgeuse ever truly alone? For over 100 years, astronomers searched for a hidden companion to Orion's famous red supergiant. Now, new observations from ESO's Very Large Telescope have revealed the clearest evidence yet that Betelgeuse has a stellar companion. Discover the science, the mystery, and why this finding is changing our understanding of one of the sky's most famous stars.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

The 365 Days of Astronomy

From February 10, 2021. Hosted by Dr. Pamela L. Gay. Scientists collected fresh data on Orion’s bright star Betelgeuse to try and understand this star that caused so much controversy. They found it’s smaller than previously calculated, and last year’s dimming was likely caused by dust, but it’s also more complex than thought. Plus, galaxies, Earth’s forests, ice on Mars, and Saturn’s moon Rhea.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

The 365 Days of Astronomy

Hosted by our editor, Richard Drumm. Far, far away from Earth, over 300 light-years away, is an incredible exoplanet called WASP-189b, in the constellation Libra, the scales. It lies a bit to the NW of Beta Librae, or Zubeneschamali, and almost exactly due north of the Libra star with my favorite star name: Zubenelgenubi! WASP-189 is the star & 189b is the planet.   It has about twice Jupiter’s mass and about 1 1/2 times its diameter. It orbits its star in 2 days & 17 hours, so it’s really close in! But this isn’t just any old planet. 189b is a giant, blazing-hot world with...
