Hidden Among Supernovae

Approximately as bright in the night sky as Proxima Centauri, this quiescent spiral galaxy known as NGC 1058 betrays its unassuming appearance with a record of supernovae and starburst activity. Captured by the Gemini Multi-Object Spectrograph (GMOS) at Gemini North, operated by NSF’s NOIRLab, the galaxy lies about 30 million light-years away in the constellation of Perseus as part of the NGC 1023 Group. A Seyfert Type 2 galaxy, NGC 1058 hosts a luminous center with a mix of blues and pinks along its arms that indicate active regions of star formation. Three supernovae have been observed in the galaxy: SN 1961V, SN 1969L, and SN 2007gr. SN 1961V has been enveloped in mystery as its explosion is yet to be understood. Although a faint shell of expanding gas can just be resolved by astronomers, some are skeptical because there is a remaining bright star near the position of its wake. As the ‘supernova’ gradually fades into the night, the incriminating star continues to shine with an unusually long decay time.
