The 365 Days of Astronomy

Space travel or the lack thereof. Hosted by Steve Nerlich. Dear Cheap Astronomy – Interstellar trade As regular listeners are aware, here at Cheap Astronomy, we think faster than light travel just ain’t going to happen. That limits your trade options a good deal if our potential alien trading partners are anywhere up to a hundred light years or more away.   Dear Cheap Astronomy – Why aren’t we doing more with artificial gravity Good question. As we’ve discussed on this podcast and as others have discussed on pretty much every space-related podcast there is, zero gravity – OK,...

The 365 Days of Astronomy

Hosted by: Fraser Cain and Dr. Pamela L. Gay Streamed live on Jun 9, 2025. Humanity has turned its focus back to the Moon, sending a fleet of spacecraft to the lunar surface. Some are run by the government, but there’s a whole new group of commercial landers bearing instruments to the lunar surface. Is this the future of lunar exploration? Space used to be a place occupied by government-funded and military missions, but today, we're seeing the rise... and fall (somersault, crash, and explosion) of missions with commercial design and funding. Let's talk about how this is good, bad, and maybe...

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 September 2024. Today's 2 topics: - When asteroid hunters follow an object in the night sky for a few hours or a couple of days they are only able to observe a snippet or tracklet of the object's hundreds to thousands of days long path around the Sun. If we only have a short sample of an orbit we loose precision to locate the object as the length of time since the last observation increases. It is thus possible to lose...

NSF NOIRLab, funded by the U.S. National Science Foundation (NSF), has released the fulldome planetarium show, Messengers of Time and Space. This free-to-download production brings the combination of the International Gemini Observatory, funded in part by NSF and operated by NSF NOIRLab, and NSF–DOE Vera C. Rubin Observatory, funded by NSF and the U.S. Department of Energy's (DOE) Office of Science and jointly operated by NOIRLab and DOE’s SLAC, to the forefront of humanity’s quest to understand our ever-changing cosmos. This podcast discusses the production process of this planetarium...

The 365 Days of Astronomy

From October 7, 2021. An analysis of the most recent sample taken from the Moon and returned by the Chang’e-5  mission shows that the basaltic rock is about two billions years old. This age implies a previously unknown heat source in the region. Plus, how plants and animals record climate change, and this week’s What’s Up.   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 Oct 12, 2010. The fact that we've found a habitable planet candidate so soon after starting our search has important implications for the number of habitable planets that may exist in our galaxy - which was estimated to be around 10 billion.     Having found Gliese 581g so soon though, may mean one of two things.  Either we were very lucky, or there are more planets out there than we thought.  Based on this discovery, it's possible that we may have many more habitable planets than originally thought.     Perhaps 20 to 30 billion stars in our galaxy may have...

The 365 Days of Astronomy

From September 22, 2008. Look around you. Breathe in some air. Everything you can see and feel was formed in a star. Today we’ll examine that long journey that matter has gone through, forged and re-forged in the hearts of stars. In fact, the device you’re using to listen to this podcast has some elements formed in a supernova explosion.   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!
