Description

Messier 90 (also known as NGC 4569) is an intermediate spiral galaxy with a weak inner ring structure. It lies about 60 million light-years away in the constellation of Virgo. The star formation in Messier 90 appears to be tapering off as evidenced by the galaxy's spiral arms appearing smooth and rather featureless. Galaxies with active star formation have knots and trails of knotted groups in their arms. However, the central region does show some significant activity where there exists around 50,000 stars of spectral types O and B (blue to blue-white hot stars) that formed around 5 to 6 million years ago (young).
