NASA's Great Observatories Provide a Detailed View of Kepler's Supernova Remnant

NASA's three Great Observatories - the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory - joined forces to probe the expanding remains of a supernova, called Kepler's supernova remnant, first seen 400 years ago by sky watchers, including famous astronomer Johannes Kepler.

The combined image unveils a bubble-shaped shroud of gas and dust that is 14 light-years wide and is expanding at 4 million miles per hour (2,000 kilometers per second). Observations from each telescope highlight distinct features of the supernova remnant, a fast-moving shell of iron-rich material from the exploded star, surrounded by an expanding shock wave that is sweeping up interstellar gas and dust.
