Our lives are ruled by calendars. And calendars are ruled by astronomy. Let’s discover the astronomy underlying the days, weeks, months and years that segment our lives.
Apr 5th: Calendars
Astronomy Cast Archive
Mar 29th: Looking Ahead
Today we are gonna gaze into the future of space and astronomy. What upcoming missions & events are we excited about?

Mar 8th: The Expansion of the Universe
It’s been a while since we checked to make sure the Universe was still expanding. Yeah, apparently, that’s still a thing. But in the last few years powerful new telescopes and expansive surveys have given us much more knowledge about what’s happening. Especially at the earliest times.
Mar 1st: The Universe’s Background Noise
You might be familiar with the cosmic microwave background, but that’s just one of the background radiations that astronomers look at. Some are well known and cataloged. While others are just starting to be possible to see at all. All of them tell us more about our Universe.
Feb 22nd: How Is A Space Mission Chosen?
Space scientists and engineers recently went through the process of deciding on their science goals, so we thought we’d spend an episode explaining how this works, and how the next generation of spacecraft and telescopes will be selected.
Feb 15th: Planet Hunting – Revisited
This is gonna be another one of those evergreen topics where we come back again and again. Finding planets. Every time we talk about this now it seems like we’ve gained thousands of new planets. Well, buckle up! New techniques will grow that by tens of thousands and even millions!

NASA’s Juno Mission just received a mission extension, adding Jupiter’s moons to the menu. Now, finally, we can talk about Juno!
