NGC 1255 is a barred spiral galaxy approximately 69 million light-years away from Earth in the constellation of Fornax.[1]
Observational history
NGC 1255 was discovered by American astronomer Edward Emerson Barnard on August 30, 1883 with the 6-inch refractor at Vanderbilt University.[3][4] He described it as a "faint nebula, not large, pretty even in light. A faint star close p and slightly south probably involved. Star is s and f the nebula by about 30'".[3] American astronomer Ormond Stone made an independent discovery in 1886 with the 26" refractor at Leander McCormick Observatory, recording "4.1'x2.0', PA 315°".[3][4]
NGC 1255 group
NGC 1255 is the namesake of the NGC 1255 group (also known as LGG 86), which contains at least 5 galaxies, including NGC 1201, NGC 1302 (fr), UGCA 61 (d), and UGCA 64.[5][6]
Supernovae
Two supernovae have been observed in NGC 1255:
- SN 1980O (Type II, mag. 17) was discovered by German astronomer Hans-Emil Schuster with the 1.0-m Schmidt telescope on October 30, 1980.[7][8][9] The supernova was located at the following coordinates: RA 03h 13m 27s, Dec -25° 44.50′ (J2000 epoch).[7][1] By December 30, 1980 the supernova had faded by about 4 magnitudes and showed strong P-Cyg-type profiles.[8]
- SN 2022ame (Type II, mag. 17.3), was discovered by Kōichi Itagaki on January 27, 2022.[10]
