Description

Messier 90 (also known as M90 and NGC 4569) is a spiral galaxy about 60 million light-years away in the constellation Virgo. It was discovered by Charles Messier in 1781. Messier 90 is a member of the Virgo Cluster. The galaxy is located approximately 1°.5 away from the subgroup centered on Messier 87. Its visual appearance is that of a tightly wound spiral with smooth, bright spiral arms. It is believed that the only active star formation is taking place within the dark dust lanes near the center of the galaxy. M90 has a visual magnitude of only 9.5, making it a tough target for binocular observers. Large telescopes will provide the best viewing.
