NGC 7038 is an intermediate spiral galaxy located about 210 million light-years away in the constellation of Indus.[2][3] Astronomer John Herschel discovered NGC 7038 on September 30, 1834.[4]
Three supernovae have been observed in NGC 7038. SN 1983L (mag. 17.1) was discovered on June 14, 1983.[5] SN 2010dx (type II, mag. 17.4) was discovered on June 8, 2010.[6] SN 2018hsa (type Ia, mag. 16) was discovered on November 1, 2018.[7]
NGC 7038 along with NGC 7014 are the brightest members of Abell 3742.[8][9] Abell 3742 is located near the center of the Pavo–Indus Supercluster.[10]
