Astronomers using data from NASA’s WISE mission have discovered millions of supermassive black holes.
Nebula - a massive interstellar cloud of dust, hydrogen, helium and other ionized gases.
The aftermath of the death of a massive star is shown in beautiful detail in this composite image of G292.0+1.8. In color is the Chandra X-ray Observatory image - easily the deepest X-ray image ever obtained of this supernova remnant - and in white is optical data from the Digitized Sky Survey. Although considered a "textbook" case of a supernova remnant, the intricate structure shown here reveals a few surprises.
The robotic Cassini spacecraft now orbiting Saturn recently drifted in the giant planet's shadow for about 12 hours and looked back toward the eclipsed Sun. Saturn's rings light up so much that new rings were discovered: Saturn's E ring, the ring created by the newly discovered ice-fountains of the moon Enceladus, and the outermost ring visible above. Far in the distance, visible on the image left just above the bright main rings, is the almost ignorable pale blue dot of Earth.
