When the Hubble Space Telescope imaged a seemingly empty region of sky for over 11 days, it turned out to not be empty at all, but full of the faintest and farthest galaxies in the universe. This was named the Hubble Ultra Deep Field (HUDF). As astronomers have measured the distances of these galaxies, a new animation shows the 3D aspect of this image. Join us as we dive into the deep end of the cosmos in this month's Ask the Astronomers Live to learn about this new animation and what it can tell us about the 13-billion-year history of our universe.
