A Tour of Eta Carinae
A Tour of Eta Carinae
New Chandra data are helping astronomers better understand how the two stars in Eta Carinae interact with one another through powerful winds blowing off their surfaces. (2014-08-27)


Kepler's Supernova Remnant in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): This image of Kepler's supernova remnant shows the expanding ball of debris from a supernova explosion in our galaxy. The supernova itself was seen in 1604 by Johannes Kepler and others. The different colors in the Chandra X-ray data show different energies in the supernova remnant, and optical data from the Digitized Sky Survey shows stars in the field. The Kepler supernova was the thermonuclear explosion of a white dwarf. New analysis suggests that the supernova explosion was not only more powerful, but might have also occurred at a greater distance, than previously thought.
