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.
NGC 1532 may possess several dwarf companion galaxies. The galaxy is clearly interacting with one of these galaxies, the amorphous dwarf galaxy NGC 1531. The tidal forces from this interaction have created unusual plumes above the disk of NGC 1532.
 The larger galaxy (NGC1532) is a spiral, and from our point of view within the Milky Way it is seen as nearly edge-on. Intense reddish star-forming regions spatter the edges of the dusty arms silhouetted in the foreground against the galactic disk. The three-dimensional nature of the galaxy is revealed by the background spiral arms dimmed by intervening gas and dust. The smaller of the galactic pair (NGC1531) is dwarfed by its larger companion in much the same fashion as the Large Magellanic Cloud is by our Milky Way. Hints of interaction between these two galaxies are seen in at least two stray associations of stars and glowing red clumps of hydrogen gas. A warp in a background spiral arm of NGC1532 and a possible bridge of matter that connect the pair suggest continued influences between the two galaxies. This pair is located about 55 million light-years away toward the southern constellation of Eridanus. It is part of a larger group that includes at least one other dwarf galaxy outside the field of this image. The mass of NGC1532 is estimated to be slightly greater than that of our Milky Way.
The pair of galaxies NGC 1531/2, engaged in a spirited waltz, is located about 70 million light-years away towards the southern constellation Eridanus (The River). The deformed foreground spiral galaxy laced with dust lanes NGC 1532 is so close to its companion — the background galaxy with a bright core just above the centre of NGC 1532 — that it gets distorted: one of its spiral arms is warped and plumes of dust and gas are visible above its disc. The cosmic dance leads to another dramatic effect: a whole new generation of massive stars were born in NGC 1532 because of the interaction. They are visible as the purple objects in the spiral arms.his lopsided cosmic tug of war is a snapshot of how large galaxies grow and evolve by devouring smaller galaxies, absorbing their stars and star-forming material. A similar process has happened in the Milky Way, possibly six times in the past, leaving vast streams of stars and other signs in the halo of the Milky Way. 

Despite its small stature, however, the dwarf galaxy has also been exerting a noticeable gravitational influence on its larger companion, distorting one of its spiral arms, which can be seen rising above the galactic plane. Additionally, plumes of gas and dust can be seen between the two galaxies, like a bridge of stellar matter held in place by the competing tidal forces. This interaction has also triggered bursts of star formation within both galaxies. The process of absorbing a smaller companion galaxy is starkly different from the cataclysmic merger of two spiral galaxies of comparable size. In the latter case, two massive galaxies collide to form an entirely distinct galaxy with its own shape and characteristics. This type of galactic merger will happen to the Milky Way when it merges with the Andromeda Galaxy four billion years from now.
