Type: Gal
Surface brightness: 11.6
Class: SA(s)a
Dimensions: 7' x 2'
Magnitude: 8.2
PA: 89
Notes:
P. Mechain first noted it in May 1781; Messier added it to his copy of Connaissance
des Temps in 1784, and later astronomers added it to his original catalog.
William Herschel was probably the first
to see the dark lane that bisects its face.
It is the most massive of all the Messier
objects (weighing in at 1.3 trillion suns), and
the most luminous. The bright disk is
82,000 light years in diameter, but the faint
arms probably extend out to 130,000 light
years diameter or more.
This galaxy was the first one in which
Vesto Sliper (of Lowell Observatory)
measured a red shift, a phenomenon that at
the time was not understood; it was not until
1923 when Edwin Hubble proposed that the
universe was expanding and that the
galaxies were individual "island universes"
that Slipher's work was recognized for the
discovery that it was. (Remember that at
this time, the galaxies were thought to be
NGC 4594 (M104, The Sombrero)
part of the Milky Way, and when Slipher
Galaxy (Sa)
announced a red shift suggesting a velocity

these patches of foggy light were
extragalactic.)
It is a member of the Virgo Cluster and a Seyfert galaxy.
