NGC 150 (also known as PGC 2052) is a barred spiral galaxy in the constellation Sculptor. It is about 63 million light years away from the Solar System, and it has a diameter of about 94,000 light years.[3] It was discovered by Lewis A. Swift on 20 November 1886.[4]
Supernovae
[edit]Two supernovae have been observed in NGC 150:
- SN 1990K (Type II, mag. 14) was discovered by Robert Evans on 25 May 1990.[5][6] It was reported to be similar to SN 1987A.[7]
- SN 2025mb (Type IIb, mag. 18.011) was discovered by ATLAS on 15 January 2025.[8] Initially classified as Type Ia, it was later determined to be Type IIb.[8]
