Youngest Supernova in Milky Way Found
G1.9+0.3A, seen here in a composite x-ray, radio, and infrared image, is the Milky Way's youngest supernova, a new study has found.
Estimated at just 140 years old, G1.9+0.3 is at least 200 years younger than the next oldest known supernova, Cassiopeia A, which was discovered in the 17th century A.D.
"Cas A had been the reigning youngest remnant for so long that it took a while to sink in that we had found something less than half its age," Reynolds said.
If it weren't so obscured by dust, people in the late 1800s would likely have seen G1.9+0.3 appear in the constellation Sagittarius.
Isn't that just the coolest thing you ever saw!!!!???
