Galaxy in the constellation Leo
From Wikipedia, the free encyclopedia
NGC 2927 is a large barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 7830 ± 20 km/s, which corresponds to a Hubble distance of 376.7 ± 26.4 Mly (115.49 ± 8.09 Mpc).[1] In addition, three non-redshift measurements give a distance of 393.56 ± 2.88 Mly (120.667 ± 0.882 Mpc).[2] The galaxy was discovered by German astronomer Heinrich d'Arrest on 21 February 1863.[3]
