NGC 140 is a spiral galaxy in the constellation of Andromeda. It was discovered by Truman Henry Safford on October 8, 1866.

Historical Information

Safford's discovery in 1866 was published in the appendix of an obscure paper. Sixteen years later, on November 5, 1882, Edouard Stephan discovered the same object, but was unaware of Safford's earlier discovery. Wolfgang Steinicke's version of the catalog lists Safford as the discoverer.

Supernova

One supernova has been observed in NGC 140: SN 2025wug (Type IIb, mag. 16) was discovered by ATLAS on 2 September 2025.
