X-ray Vision Reveals the Insides of Stars
X-ray Vision Reveals the Insides of Stars
Each of these four fabulous photographs shows the remains of an exploded star - called a supernova remnant. (2014-07-23)


Crab Nebula in 60 Seconds

View/Listen
Narrator (Megan Watzke, CXC): The Crab Nebula is one of the most studied objects in the night sky. First observed by Chinese astronomers in 1054 A.D., and possibly others, this supernova remnant and its neutron star have become favorite targets for amateur and professional astronomers alike. This version of the Crab Nebula combines data from three different telescopes. X-ray data from Chandra, in light blue, show the super-dense neutron star that is the core of the exploded star, which is shooting a blizzard of high-energy particles into the expanding debris field. This super-energetic outflow is striking the cooler gas and dust seen in optical data from Hubble as well as infrared light from Spitzer. The Crab Nebula contains incredibly intriguing science, and provides perhaps one of the most stunning images in all of astronomy.
