Messier 87 is an enormous elliptical galaxy in the direction
of the constellation Virgo. For decades astronomers have been fascinated
by a powerful jet of material spewing outward from the core of the galaxy.
More recently, Hubble
Space
Telescope imaging provided astronomers with some of the best evidence yet for
the existence of super-massive black holes in the centers
of galaxies. It is safe to say that M87 will fascinate astronomers for
decades to come.
