The light Hubble sees today may have taken thousands, millions, even billions of years to reach us, carrying the story of events that happened in the distant past. Click on the pictures at the top of this page to see how far we are looking back through time.
Light from the farthest regions of the universe takes billions of years to reach Hubble. Amazingly, when we look at these most distant of all views, we see events that occurred before Earth itself existed — when the universe was merely a fraction of its present age.
