365 Days of Astronomy - Weekly Edition ·

2019/02/11

One of the most influential astronomers in the 20th Century was Fritz Zwicky. He had his hand in the discovery of dark matter, gravitational lensing, supernovae and neutron stars. And he also worked on a few more controversial ideas like, uh, tired light. Let's learn more about Zwicky.

Ep. 516: Polar Vortices

365 Days of Astronomy - Weekly Edition ·

2019/02/04

It's cold right now. Okay, fine, here on Vancouver Island, it's actually pretty warm. But for the rest of Canada and big parts of the US, it's terrifyingly cold. Colder than Mars or the North Pole cold. This is all thanks to the break up of the polar vortex. What are polar vertices, how do they form, and where else to we find them in the Solar System?
