Nasa 'elated' after new telescope uncovers 'previously invisible space objects'

In what has left scientists at the space agency “elated”, the $320m (£195m) sky-mapping spacecraft has for the first time identified previously thousands of unseen space objects including stars, asteroids, dust clouds, comets and even a new galaxy.

Using technology to photograph the entire night sky one and a half times in infra-red light, Nasa said the telescope detected more than 25,000 new asteroids since beginning operations late last year.

Astronomy experts said almost 100 were considered "near Earth”, or within 30 million miles (48 million km). None, they added, posed any real threat to Earth.

The telescope also sighted 15 new comets and hundreds of potential brown dwarfs, or failed stars. It also confirmed the existence of 20 "dwars", including some of the coldest ever known.

WISE also detected what Nasa scientists believe is an ultra luminous galaxy, more than 10 billion light years away that formed from other colliding galaxies.

The findings, released late last week, have left the space agency thrilled. Most of the objects have been invisible to most other telescopes before now.

This is a pretty amazing find if you think about. They discovered a whole new galaxy? Makes you wonder if they found anything they didn't see fit to tell us.
