Hubble spies curious galaxy moving a little closer

This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies ...

Hubble peers at cosmic blue bauble
