The explosive death of a star created this debris cloud, Cassiopeia A, still expanding at shock-wave speeds. This photograph combines an optical image taken by Ken Crawford of the Rancho Del Sol Observatory and X-ray images from NASA's orbiting X-ray telescope NuSTAR, the first telescope to create focused images of high-energy X-rays.

~~Supernova Remnant Cassiopeia A (NASA, Chandra) ~ for the first time, a multiwavelength three-dimensional (3-D) reconstruction of a supernova remnant has been created. This stunning visualization of Cassiopeia A (Cas A), the result of an explosion approximately 330 years ago by NASA's Marshall Space Flight Center~~
Massive star IRS 4 is beginning to spread its wings. Born about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), pictured above. It lies about 2000 light-years away toward the constellation of the Swan (Cygnus).
A region of glowing gas in the Sagittarius arm of the Milky Way galaxy, NGC 3576 is located about 9,000 light years from Earth. Such nebulas present a tableau of the drama of the evolution of massive stars, from the formation in vast dark clouds, their relatively brief (a few million years) lives, and the eventual destruction in supernova explosions. The diffuse X-ray data detected by Chandra (blue) are likely due to the winds from young, massive stars that are blowing throughout the nebula.
