This new view of the historical supernova remnant Cassiopeia A, located 11,000 light-years away, was taken by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. While the star is long dead, its remains are still bursting with action.
This mosaic of images from NASA's WISE Telescope is in the constellation of Cassiopeia. This region contains a large star forming nebula within the Milky Way Galaxy, sometimes called the Heart Nebula, and is over 6 thousand light-years from Earth.
For the first time, a multiwavelength three-dimensional reconstruction of a supernova remnant has been created. This visualization of Cassiopeia A, or Cas A, the result of an explosion approximately 330 years ago, uses data from several NASA telescopes.
The Cassiopeia A supernova's first flash of radiation makes six clumps of dust (circled in annotated version) unusually hot. The supernova remnant is the large white ball in the center. This infrared picture was taken by NASA's Spitzer Space Telescope.
This composite image from NASA's Spitzer Space Telescope shows the remnant of a star that exploded, called Cassiopeia A (center) and its surrounding 'light echoes' -- dances of light through dusty clouds, created when stars blast apart.
A seething cauldron of light appears to bubble and ooze around the remains of a giant star that astronomers have been watching tear itself apart for the last 300 years. Different observations taken over three years by NASA' Spitzer Space Telescope.
The elements and molecules that flew out of the Cassiopeia A star when it exploded about 300 years ago can be seen clearly for the first time in this plot of data, called a spectrum, taken by NASA's Spitzer Space Telescope.
This image from NASA's Spitzer Space Telescope shows the scattered remains of an exploded star named Cassiopeia A. Spitzer's infrared detectors 'picked' through these remains and found that much of the star's original layering had been preserved.
Order Amidst Chaos of Star's Explosion (Artist Concept)
This artist's concept shows the explosion of a massive star, the remains of which are named Cassiopeia A. NASA's Spitzer Space Telescope found evidence that the star exploded with some degree of order.
This artist concept shows that NASA's Spitzer Space Telescope found evidence that this star, the remains of which are named Cassiopeia A, exploded with some degree of order, preserving chunks of its onion-like layers as it blasted apart.
This false-color image from three of NASA's Great Observatories provides one example of a star that died in a fiery supernova blast. Called Cassiopeia A, this supernova remnant is located 10,000 light-years away in the constellation Cassiopeia.
This Spitzer Space Telescope composite shows the supernova remnant Cassiopeia A (white ball) and surrounding clouds of dust (gray, orange and blue). It consists of two processed images taken one year apart.
