The Star Spot

Feature Guest: Ingrid Stairs

In February scientists announced the first ever discovery of gravitational waves, tiny distortions in the fabric of space-time predicted by Einstein exactly 100 years ago. The Laser Interferometer Gravitational-Wave Observatory, or LIGO, made the historic detection by studying two colliding black holes, but singularities aren’t the only source of gravitational waves.

Here to tell us how pulsars, the lighthouses of the galaxy, can be used to study gravitational waves and help us understand the forces of our universe, today we’re joined at The Star Spot by pulsar authority Ingrid Stairs

The Star Spot is Now on the Radio!

The The Star Spot podcast is now The Star Spot podcast and radio show. That’s right. Your favourite astronomy program is now travelling through space, specifically the 1280AM frequency. Our broadcaster, CJRU The Scope at Ryerson, is now available on the radio dial, which means you can join us at The Star Spot at 1280AM every Sunday 8PM and Tuesday 6PM Eastern Time.

Current in Space

We know the late heavy bombardment period was critical to the eventual emergence of life on Earth. But since Earth wasn't the only planet that went through such an ordeal, Anuj explains what that implies for life in the solar system. And Dave shares new evidence of the effect of ancient supernova explosions on our planet.
