Galaxy NGC 2841

The relatively faint galaxy NGC2841 is one of the early recognized spiral galaxies, first discovered by William Herschel in 1788.  It has been classified as of Hubble type SA(r)b galaxy. The western part is partly obscured by the galaxy's halo, reducing the contrast in this area. It is showing a similar appearance as the well-known galaxy M 63.

The distance to this galaxy has been determined recently at 47 million light years, and it has a diameter of over 150,000 light-years. The appearance resembles symmetrical spiral arms showing up as with dark dust areas and blue star forming areas, brightening slowly from outward and then rapidly to the nuclear region. Several supernovae have been reported in this galaxy.

The rapid outflows of gas from giant stars, and supernova explosions in the disk of a galaxy create huge shells or bubbles of hot gas that expand rapidly and rise above the disk like plumes of smoke from a chimney, shown in a X-ray image from Chandra.
