Hubble Captures a New View of Galaxy M90

(WFC3) replaced WFPC2 in 2009 and Hubble used WFC3 when it turned its aperture to Messier 90 again in 2019 and 2023. That data resulted in this stunning new image, providing a much fuller view of the galaxy’s dusty disk, its gaseous halo, and its bright core.

The inner regions of M90’s disk are sites of star formation, seen here in red H-alpha light from nebulae. M90 sits among the galaxies of the relatively nearby Virgo Cluster, and its orbit took M90 on a path near the cluster’s center about three hundred million years ago. The density of gas in the inner cluster weighed on M90 like a strong headwind, stripping enormous quantities of gas from the galaxy and creating the diffuse halo we see around it. This gas is no longer available to form new stars in M90, with the spiral galaxy eventually fading as a result.

M90 is located 55 million light-years from Earth, but it’s one of the very few galaxies getting closer to us. Its orbit through the Virgo cluster has accelerated so much that M90 is in the process of escaping the cluster entirely. By happenstance, it’s moving in our direction. Astronomers have measured other galaxies in the Virgo cluster at similar speeds, but in the opposite direction. As M90 continues to move toward us over billions of years, it will also be evolving into a lenticular galaxy.
