To celebrate Chandra's deployment from the shuttle Columbia on July 23, 1999, the telescope team is releasing four new pictures of supernova remnants: the Crab Nebula, Tycho, G292.0+1.8 and 3C58. Chandra's X-ray vision is well-suited to reveal the hot spots in those celestial blast zones.
"Chandra changed the way we do astronomy," Paul Hertz, NASA's Astrophysics Division director, said in a news release on Tuesday. "We're fortunate we've had 15 years — so far — to use Chandra to advance our understanding of stars, galaxies, black holes, dark energy and the origin of the elements necessary for life."
To mark the anniversary, Chandra scientists will participate in a Google+ Hangout starting at 3 p.m. ET Tuesday.
