- G1.9+0.3 abstract "Supernova remnant G1.9+0.3 in the constellation Sagittarius is the youngest known supernova remnant (SNR) in the Milky Way Galaxy. The remnant's young age was established by combining data from NASA's Chandra X-ray Observatory and the VLA radio observatory. It was a type Ia supernova believed to have exploded about 25,000 years ago, and the signal began reaching us 140 years ago (as of 2008). The light from the supernova would have been visible to 19th Century astronomers, had it not been obscured by the dense gas and dust of the Galactic Center. Prior to this discovery, the youngest-known Milky Way supernova remnant was Cassiopeia A, at about 330 years. The remnant has a radius of over 1.3 light years.".
