All Eyes on Oldest Recorded Supernova This image combines data from four different space telescopes to create a multi-wavelength view of all that remains of the oldest documented example of a supernova, called RCW 86
Faint supernova remnant of Simeis seen towards the constellation Taurus. This image is a color composite of 66 blue and red color band images from the National Geographic Palomar Observatory Sky Survey taken with the wide field Samuel Oschin Telescope
The North American Nebula. This swirling landscape of stars is known as the North American nebula. In visible light, the region resembles North America, but in this new infrared view from NASA's Spitzer Space Telescope, the continent disappears.
NASA's NuSTAR telescope array generated the first map of radioactivity in the remnants of an exploding star, or supernova. Blue in this image of Cassiopeia A represents radioactive material. Click through to see other wonders of the universe.
This is a composite image of the brightest supernova remnant in optical light in the Large Magellanic Cloud. The Chandra X-ray image (blue) shows million-degree gas in the center. Much cooler gas at the outer parts of the remnant is seen in.
Australian astrophysicist Brian Schmidt chose this Hubble photo of Supernova SN as his favorite space image, which he called "the poster child of a type Ia supernovae." The supernova is the bright spot on the lower left, shown near the galaxy NGC 4526
