Looking at Galaxies and understanding how they form, what they are made up of, how they move and interact are all important questions that go towards helping our understanding of the Universe. Galaxies are amazing things – we move around in our galaxy, The Milky Way, at it’s centre it has a supermassive black hole, Sagittarius A*, it is a new(ish) spiral galaxy and it is our galactic home. They are also the biggest things in the Universe and some bigger than others!
At the University of Melbourne, Dr Michele Trenti spends much of his research time analysing images from the Hubble Space Telescope which look deep into space, to find the oldest galaxies in the Universe. Come and hear Dr Trenti talk about the hunt for the oldest of galaxies and what they can tell us in the Scienceworks Energy Lab on the Lower Ground Floor.
Hunting for the first galaxies in the Universe with the Hubble Space Telescope
What is a galaxy and how does it form? I will address these fundamental questions of astronomy by focusing on the earliest stages of assembly, which can be explored by observing distant galaxies. In fact, because of the finite speed of light, distant objects are seen as they were in the past: The Hubble Space Telescope observations I will present are allowing us to reach as far as 13.3 billion light years away, showing us how galaxies looked like when the Universe was just 500 Million years old.
