[5] [6] As an elliptical galaxy, the galaxy is a spheroid rather than a flattened disc, accounting for the substantially larger mass of M87. Within a radius of 32 kiloparsecs (100,000 light-years), the mass is (2.4 ± 0.6) × 10 12 times the mass of the Sun, [ 47 ] which is double the mass of the Milky Way galaxy. [ 53 ]

The proper distance provides a measurement of how far a galaxy is at a fixed moment in time. At the present time the proper distance equals the comoving distance since the cosmological scale factor has value one: a ( t 0 ) = 1 {\displaystyle a(t_{0})=1} .
The most famous elliptical galaxy is M87, which has up to 2.4 trillion stars. Astronomers recently used a combination of special telescopes to image the center of M87 and the supermassive black ...
The Virgo Cluster is a cluster of galaxies whose center is 53.8 ± 0.3 Mly (16.5 ± 0.1 Mpc) [2] away in the constellation Virgo.Comprising approximately 1,300 (and possibly up to 2,000) member galaxies, [3] the cluster forms the heart of the larger Virgo Supercluster, of which the Local Group (containing the Milky Way galaxy) is a member.
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
The Pentagon has spent more than $14 trillion since 9/11, with up to 50% going to defense contractors, Brown University's Cost of War project found.
