NGC 4414 is an unbarred spiral galaxy located in the constellation of Coma Berenices, at about 62 million light-years away from Earth.[1] It has an estimated size of 82,500 light-years across and it is often called the Dusty Spiral Galaxy.[2]
NGC 4414 is a flocculent spiral galaxy, a type of spiral galaxy that have short, patchy, and broken pieces of spiral arms. It was imaged by the Hubble Space Telescope in the 1990s to help astronomers calculate distances to faraway galaxies by studying its variable stars.[1]
Four supernovae have been observed in this galaxy:
- SN 1974G: A Type I supernova discovered on April 20, 1974, by Miss W. Burgat.[3]
- SN 2013df: A Type IIb supernova discovered on June 7, 2013, by the Italian Supernovae Search Project.[4]
- SN 2021J: A Type Ia supernova discovered on January 1, 2021, by the ALeRCE team.[5]
- SN 2023hlf: A Type II supernova discovered on May 1, 2023, by the Zwicky Transient Facility.[6]
