M58 - Barred Spiral Galaxy in Virgo

M 58 (also known as NGC 4579) is a barred spiral galaxy in the constellation of Virgo, the virgin. It lies approximately 68 million light-years away and is 107,000 light-years in diameter. It is one of the brightest galaxies in the Virgo Cluster and is one of only four barred spiral galaxies in Messier's catalog. Charles Messier discovered it on April 15, 1779. Compared with other barred spiral galaxies, M 58 is relatively low in star formation activity. It is classified as a Seyfert galaxy. These are galaxies with extremely bright nuclei that produce spectral line emission from highly ionized gas.
