Weltraumteleskop. Hubble-Weltraumteleskop. Das Hubble-Weltraumteleskop (englisch Hubble Space Telescope, kurz HST) ist ein Weltraumteleskop, das von der NASA und der ESA gemeinsam entwickelt wurde und nach dem Astronomen Edwin Hubble benannt ist.
Es arbeitet im Bereich des elektromagnetischen Spektrums vom Infrarotbereich über das sichtbare Licht bis in den Ultraviolettbereich. Nach dem Aussetzen des Teleskops stellte sich schnell heraus, dass die Bildqualität nicht den Erwartungen entsprach. Main Hubble Page. ESA/Hubble. Hubble's deepest view ever of the Universe unveils earliest galaxies. Astronomers today unveiled the deepest portrait of the visible Universe ever achieved by humankind.
Called the Hubble Ultra Deep Field (HUDF), the million-second-long exposure reveals the first galaxies to emerge from the so-called "dark ages", the time shortly after the big bang when the first stars reheated the cold, dark Universe. The new image should offer new insights into what types of objects reheated the Universe long ago. This historic new view is actually two separate images taken by Hubble's Advanced Camera for Surveys (ACS) and the Near Infrared Camera and Multi-object Spectrometer (NICMOS).
Both images reveal some galaxies that are too faint to be seen by ground-based telescopes, or even in Hubble's previous faraway looks, called the Hubble Deep Fields (HDFs), taken in 1995 and 1998. "Hubble takes us to within a stone's throw of the big bang itself," says Massimo Stiavelli of the Space Telescope Science Institute in Baltimore, USA, and the HUDF project lead.
