NGC 1531 & NGC 1532 Bundle 10h20 CHI-1
NGC1531 and NGC1532 are a pair of gravitationally interacting galaxies located about 50 millions light years away in the Eridanus constellation.
The largest of the two is the barred spiral NGC 1532 which appears almost edge on, while the smallest one is the dwarf galaxy NGC1531 which appears as a mere distortion, as most of the galaxy has already been stripped of the bulk of its material.
This interaction caused intense stars formation in the foreground spiral as evidenced by the young and bright blue star clusters located all along the front spiral arm.
Although NgC1532 is seen almost from the edge, astronomers believe this system looks like the famous spiral pair seen from the front and its companion known as M51, the Whirlpool Galaxy.
