Astronomers have found that sometimes the Universe changes. Things move, things explode, things get brighter or dimmer. In fact, knowing this has helped astronomers discover some very important aspects of the Universe. Today we begin a two part series on Transients and their role in astronomy.

Ep. 518: When the Universe tried to Declare War
We always say the Universe is trying to kill us. But there was this one time, when the Universe used our own fear of nuclear attack against us, nearly setting off a global nuclear war. Nice try Universe, we’re on to you now.
Ep. 517: Fritz Zwicky and the Zwicky Transient Facility
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
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?
