Encyclopedic overview

NGC 1527 is a lenticular galaxy in the constellation of Horologium. Its velocity with respect to the cosmic microwave background is 1,178±17 km/s, which corresponds to a Hubble distance of 56.7 ± 4.1 Mly (17.37 ± 1.27 Mpc). Additionally, 10 non-redshift measurements give a mean distance of 55.87 ± 3.62 Mly (17.130 ± 1.111 Mpc). It was discovered by Scottish astronomer James Dunlop on 28 September 1826.

NGC 1527 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.
