Kepler's Supernova Remnant in 60 Seconds

Narrator (Megan Watzke, CXC):The supernova explosion that created this object was witnessed on Earth about 400 ago years by many skywatchers, including the astronomer Johannes Kepler. This object, which now bears Kepler's name, is the remains of a massive star's demise. Visible-light from Hubble reveals where the supernova shock wave is slamming into the densest regions of surrounding gas. Spitzer shows microscopic dust particles that have been heated by the supernova shock wave. The X-ray data from Chandra show regions of very hot gas as well as extremely high-energy particles. The remnant of Kepler's supernova is possibly the last supernova seen to explode in our Galaxy. It is located about 13,000 light years from Earth.
