G1.9+0.3 is a supernova remnant (SNR) in the constellation of Sagittarius. It is the youngest-known SNR in the Milky Way, resulting from an explosion the light from which would have reached Earth some time between 1890 and 1908. The explosion was not seen from Earth as it was obscured by the dense gas and dust of the Galactic Center, where it occurred. 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. The remnant has a radius of over 1.3 light-years.

W49B (also known as SNR G043.3-00.2 or 3C 398) is a nebula in Westerhout 49 (W49). The nebula is a supernova remnant, probably from a type Ib or Ic supernova that occurred around 1,000 years ago. It may have produced a gamma-ray burst and is thought to have left a black hole remnant.

G292.0+01.8 is a supernova remnant located in the constellation Centaurus. It first gained notice as a strong radio source, and eventually deep images revealed a hot optical nebula at the location. It lies about 15,000 light years away.

G350.1-0.3 is a supernova remnant which is located in the constellation Scorpius. It is in the Milky Way, and possibly associated with a neutron star (XMMU J172054.5-372652) formed in the same supernova explosion. The object was formerly mistakenly classified as a distant galaxy.

G299.2-2.9 is a supernova remnant in the Milky Way, 16,000 light years from Earth. It is the remains of a Type Ia supernova. The observed radius of the remnant shell translates to approximately 4,500 years of expansion, making it one of the oldest observed Type Ia supernova remnants.
