G1.9+0.3
(recent supernova remnant in Sagittarius)
G1.9+0.3 is a radio source (RS, its identifier "G1.9+0.3" consists of its
galactic coordinates) that is a supernova remnant of a supernova
presumed to have occurred in the decades circa 1900, and is the
youngest SN remnant known, i.e., the result of the most recent known
Milky Way SN. The SN was not observed, apparently due to
cosmic dust obscuration. The remnant's age is estimated by the
observed expansion of its angular diameter since the RS's
discovery. The RS was discovered and considered a SN remnant
candidate in 1984, and further observation in 2008 confirmed the
theory. The SN is thought to have been a Type Ia supernova.
