Have you ever wanted to travel back to the beginning of time to see what some galaxies in our universe looked like? Well, now you can! (Well, almost...!)
Astronomers have recently released a new and updated version of our deepest view into the universe - the Hubble eXtreme Deep Field (XDF). The XDF follows about eight years after the previous Hubble Ultra Deep Field (HUDF) image, which was released in 2004.
The XDF image was created by the assembly of almost 10 years of Hubble telescope photographs, focused on just a portion from the center location of the original UDF image. Even though the XDF was created from a tiny portion of our sky, it contains images approximately 5,500 galaxies - some of which are estimated to date back to 13.2 billion years in time, when they were relatively young and still growing (!).
You can learn more at the HubbleSite: Hubble Goes to the eXtreme to Assemble Farthest Ever View of the Universe, and you can find the XDF and related images and illustrations on their Release Images page. It is fascinating to download the high resolution version, then zoom in and pan around, and see the seemingly endless number of massive galaxies...!
