Deutsch: Der Krebsnebel (NGC 1952).
Diese zusammengesetzte Falschfarben-Aufnahme verwendet Daten von drei großen Observatorien der NASA: Anteile des Chandra-Röntgenbilds werden in hellblau angezeigt; optische Anteile des Hubble-Weltraumteleskops erscheinen in grün und dunkelblau; Infrarot-Anteile des Spitzer-Weltraumteleskops sind rot eingefärbt. Der Neutronenstern mit ähnlicher Masse wie unsere Sonne erscheint als heller Stern in der Bildmitte - eine schnell rotierende Kugel mit etwa 19 km Durchmesser.English: Crab Nebula (NGC 1952).
This composite image uses data from three of NASA's Great Observatories. The Chandra X-ray image is shown in light blue, the Hubble Space Telescope optical images are in green and dark blue, and the Spitzer Space Telescope's infrared image is in red. The size of the X-ray image is smaller than the others because ultrahigh-energy X-ray emitting electrons radiate away their energy more quickly than the lower-energy electrons emitting optical and infrared light. The neutron star, which has the mass equivalent to the sun crammed into a rapidly spinning ball of neutrons twelve miles across, is the bright white dot in the center of the image. |
