How can we study the origins of the universe? How do we know how galaxies form, and how do they evolve over time? Come along and find out!
Unveiling the properties of stars and supermassive black holes in distant galaxies using the James Webb Space Telescope
Dr. Aayush Saxena (Post Doctoral Researcher in Extragalactic Astrophysics)
The discovery of the most distant galaxies in the universe, containing the first generation of stars and primordial supermassive black holes, lies at the cutting edge of astronomy. The Hubble Space Telescope has detected galaxies formed only a few hundred million years after the Big Bang, and with the launch of the James Webb Space Telescope it will be possible to study the stars and supermassive black holes in these distant galaxies in unparalleled detail. I will explain how the James Webb Space Telescope will shed light on the build up of stars and black holes within primordial galaxies.

We are stardust: the life cycle of gas in galaxies
Dr. Kate Pattle (Royal Society University Research Fellow at UCL)
In this talk I will discuss how new stars are formed from gas clouds in galaxies like the Milky Way, how those stars — some like our own Sun, but most not — interact with their surroundings while they live, and where the gas that they are composed of goes when they die. I will also discuss how the properties of stars and the planets around them may change as the next generation of stars forms from the remains of the stars that preceded them, and potential links between star formation and galaxy evolution.
