Astrophysics: Hidden Universe uncovered
Ian Smail1
Abstract
An experiment flying on a balloon at the edge of the atmosphere offers the deepest far-infrared view of the sky yet achieved, revealing previously unidentified, dust-obscured, star-forming galaxies in the early Universe.
To the human eye, the night sky is a canopy of stars. With the aid of a small telescope it is possible to see our nearest Galactic neighbours, and using sensitive charge-coupled detectors and the world's largest optical telescopes we can go beyond this and peer into the farthest reaches of the Universe.
