Advent calendar December 10: Deep Space IR

What does empty space look like? A lot more than you think! This is the latest release of the Hubble Ultra Deep Field image that was taken recently with the IR camera installed on the last servicing mission. This image is about the same location as the first famous image from a few years ago. This looks back to a point just 600 million years after the "Big Bang". Hubble is a time machine as well as a telescope!
