NGC 7292
Galaxy in the constellation Pegasus
From Wikipedia, the free encyclopedia
NGC 7292 is a barred irregular galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 652±24 km/s, which corresponds to a Hubble distance of 31.4 ± 2.5 Mly (9.62 ± 0.76 Mpc).[1] However, six non-redshift measurements give a larger mean distance of 38.55 ± 4.13 Mly (11.820 ± 1.266 Mpc).[2] It was discovered by French astronomer Édouard Stephan on 29 August 1872.[3]

NGC 7292 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]
