Spiral Galaxy NGC 2841 in Ursa Major
Summary[edit]
| Description |
English: NGC 2841 is an unbarred spiral galaxy in the northern constellation of Ursa Major. J. L. E. Dreyer, the author of the New General Catalog, described it as, "very bright, large, very much extended 151°, very suddenly much brighter middle equal to 10th magnitude star". Initially thought to be about 30 million light-years distant, a 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined its distance to be approximately 46 million light-years.
