Evenings with Astronomers: Finding Astronomical Fossils with Keck – Dr. Duncan Forbes

Please be patient while the video loads.

Ancient star clusters are the fossils of the astronomical world. They formed at early times in the Universe and many have survived to the present day. New discoveries made with the Keck Observatory have uncovered a host of previously unknown star clusters - some more massive than small galaxies. Join us for an engaging presentation by Professor Duncan Forbes from Swinburne University, Australia, as he shares his current research and asks us all to consider, “What is a galaxy?”

Here on Keck 2 the 1st of our 2 primary fields has just risen above the horizon, so we are busily collecting photons from distant galaxies.
Howdy! This is @rhaegal on Keck 2 with grad student Intae, searching for the most distant galaxies with deep spectroscopy on DEIMOS.
