NGC 2841


NGC 2841 is an inclined, unbarred, spiral galaxy in the constellation Ursa Major that exhibits a prominent inner ring structure. It was discovered on 9 March 1788 by William Herschel. 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 14.1 megaparsecs or 46 million light-years.

Structure

NGC 2841 is a giant spiral galaxy with properties similar to those of the Andromeda Galaxy. It is a prototypical flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous.
NGC 2841 is home to a large population of young blue stars, and a few H II regions.

LINER emission

NGC 2841 contains a low-ionization nuclear emission-line region, a type of region that is characterized by spectral line emission from weakly ionized atoms.
