The 365 Days of Astronomy

Host: Fraser Cain ( )Special Guest: This week we are excited to welcome Dr. Stephon Alexander to the WSH to chat about his new book, Fear of a Black Universe: An Outsider’s Guide to the Future of Physics, which was published on August 31.   What lurks beyond the black hole singularity in our galaxy? How did cosmic structure emerge from a chaotic and featureless early universe? Is there a hidden link between the emergence of life and the laws of physics? These questions and other major problems of theoretical physics seem beyond the reach of human knowledge. But cosmologist Stephon...

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...

Red supergiants are massive stars at the end of their lives. Theoretical predictions about how they go supernova have not matched observed data. In this encore podcast, Dr. Emma Beasor discusses recent research that attempts to explain the red supergiant problem.
