Deepest Visible-Light Photo of Cosmos

Photo: Multi-exposure snapshot of 10,000 galaxies

Click the size you would like to download:

Representing 800 exposures taken during 400 Hubble Space Telescope orbits around Earth from September 2003 to January 2004, this galaxy-studded photo is the deepest visible-light image of the cosmos ever taken. Nearly 10,000 galaxies are represented in this view, dubbed the Hubble Ultra Deep Field, which scientists describe as peering through an 8-foot-long (2.4-meter-long) straw to get a deep core sample of the universe.
