Across The Universe
This image is from Hubble's Ultra Deep Field camera. Astronomers pointed the telescope at the emptiest, blackest place in the sky and got this image. These are very distant galaxies. The tiniest, faintest dots are galaxies that are 20 to 25 billion light years away. The age of the Universe is thought to be 30 billion years old. The farther we look into the distance, the farther we look into the past. Note: 1 light year is 300 000 km/second (speed of light) x # seconds in one day x 365 (days in one year)! And that's only one light year! Multiply that by 25 billion ... that's a lot of Air Miles!
