Hubble Captures Extraordinary View of Universe
The Hubble Space Telescope (HST) has produced one of its most extraordinary views of the Universe to date. Called the eXtreme Deep Field, the picture captures a mass of galaxies stretching back almost to the time when the first stars began to shine. But this was no simple point and snap – some of the objects in this image are too distant and too faint for that. Rather, this view required Hubble to stare at a tiny patch of sky for more than 500 hours to detect all the light.
The XDF will become an invaluable tool for astronomy. The objects embedded in it will now be followed up by other telescopes. It will keep scientists busy for years, enabling them to study the full history of galaxy formation and evolution.
