Description

NGC 1532, also known as Haley's Coronet,is an edge-on barred spiral galaxy located approximately 50 million light-years from the Solar System in the constellationEridanus. The galaxy was discovered by James Dunlop on 29 October 1826.Three supernovae have been observed in NGC 1532: SN 1981A (type unknown, mag. 13.5),SN 2016iae (type Ic, mag. 17.3), and SN 2016ija (type II, mag. 16.5). NGC 1532 is one of many edge-on spiral galaxies that possesses a box-shaped bulge. This is an indication that the bulge is actually a bar. Such bars are easy to detect in face-on galaxies, where the structures can be identified visually. In inclined galaxies such as this one, however, careful analyses are needed to distinguish between bulges and bar structures.
