Expanding universe

On the 25th anniversary of the Hubble Telescope first being launched into low earth orbit, TASCHEN brings together some of its most breathtaking deep space images. Hubble's orbit outside the Earth's atmosphere allows it to take extremely high-resolution images with almost no background light. Its acute observations have answered some of the most compelling questions of time and space, and simultaneously revealed whole new mysteries, like the strange "dark energy" that sees the universe expanding at an ever-accelerated rate. With investigations into everything from black holes to exoplanets, Hubble has changed not only the face of astronomy, but also our very sense of being in the universe.
