The Hubble Space Telescope recently finished taking the deepest image of the Universe ever in the near-infrared. This unique new image was assembled from data taken in 2009 and 2010, and has enabled us to look billions of years back in time to find some of the earliest galaxies that were forming when the Universe was very young, just 5% of its current age. These tiny galaxies are the seeds that grew into the myriad great galaxies of today, like the nearby Andromeda galaxy and our own Milky Way. In this talk, Dr. Illingworth will describe how we are exploring a never-before-seen time period in the Universe and learning about the origins of galaxies.
