We think, therefore we are confused. What exactly is vacuum energy? To paraphrase various physicists and science communicators over the last few decades – anyone who thinks that a vacuum is nothing, just doesn’t get it. So what do you make of Massive Gravity? As we’ve previously discussed on Cheap Astronomy, there are a lot of people out there who want to muck about with General Relativity. After all, it is fantastic physics and a genuine theory that has been tested time and again and it keeps on passing those tests.   We've added a new way to donate to 365 Days of Astronomy to...

Good News! Over the next few years we’re gonna see a flotilla of new missions headed to Jupiter and Saturn. Why aren’t we seeing more missions to the outer planets like Uranus and Neptune, even Pluto? It turns out those places are far away. Today let’s talk about the challenges of exploring the outer, outer solar system.   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!

Hosted by: Tshiamiso Makwela. In this mini episode, we chat with Andrew “Andy” Firth, a Masters students at the South African Astronomical Observatory and the University of Cape Town.   Andrew tries to detect the faint signals of hydrogen gas in distant galaxies using a new technique. He does this through stacking data cubes of these galaxies. This clever new technique will be applied to some of the MeerKAT radio telescope data.   Growing up in the Karoo, Andrew had the pleasure of experiencing the beautiful Southern night sky. With this experience, Andy not only fell in love...

The 365 Days of Astronomy

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. In this episode we'll talk about small solar system objects that you can see in (comparatively) tiny telescopes. You don't necessarily need a real dark sky to observe these things you just need some optics. - 1 Ceres - 44 Nysa - 7 Iris - 20 Massalia   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!

Hosted by Fraser Cain. With so much attention on Mars, it's easy to forget there's a whole other Earth-sized planet nearby, worthy of exploration: Venus. And the Soviets worked really hard to tell us what it's like down on the surface of Venus with their Venera program.   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!
