NASA looking for new objects in space

10:09 am on 15 December 2009

NASA has launched a satellite which will scan the sky for objects never seen before.

The satellite is the most sensitive detector of infrared radiation ever sent into orbit. It will seek objects in the dark spaces between stars and planets - dust clouds and asteroids, and suns that have cooled down.

The American space agency says WISE will take billions of images which will allow astronomers to see the sky in greater detail than ever before.
