We know that galaxies contain lots and lots of stars. But what came first? Stars or galaxies? Do galaxies ever grow old? In this talk we will discuss a galaxy's lifetime - how they are born, how they grow and make stars, and how they fight, merge, or eat other galaxies.
Recommended age: 12-18 years but everyone is welcome!
The talk was streamed on Facebook Live. You can watch a recording of the talk here on our Facebook page (see the 'Astronomy at Home' video playlist) or by clicking on the video in the media gallery above.
