NGC 337

NGC 337
A barred spiral galaxy on a dark background. The galaxy’s central region is a pale colour due to older stars, contains some pale reddish threads of dust, and is brighter along a broad horizontal bar through the very centre. Off the bar come several stubby spiral arms, merging into the outer region of the disc. It is a cool blue colour and contains some bright sparkling blue spots, both indicating young hot stars.

NGC 337 is a barred spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is 1,331±22 km/s, which corresponds to a Hubble distance of 64.0 ± 4.6 Mly (19.63 ± 1.41 Mpc).[1] Additionally, 20 non-redshift measurements give a similar distance of 63.11 ± 1.81 Mly (19.350 ± 0.556 Mpc).[2] It was discovered on September 10, 1785 by German-British astronomer William Herschel.[3] It was described by John Dreyer as "pretty faint, large, extended, gradually a little brighter middle, 10th magnitude star 21 seconds of time to the east."[3]
