The Sombrero Galaxy
Deep within Virgo’s heart lies a showpiece spiral galaxy guaranteed to delight amateur astronomers and the general public alike. The Sombrero Galaxy is undoubtedly one of the finest objects you can see through a small telescope. M104 was the first galaxy to have a large redshift detected. Redshift refers to the direction of motion away from us caused by the universe’s expansion. In 1912, American astronomer Vesto M. Slipher discovered the Sombrero Galaxy was moving away from us at a speed of 2.2 million mph (3.6 million km/h). The Sombrero Galaxy’s lens shape and the dark dust lane that splits it are easy to spot. The galaxy’s two sections have unequal brightnesses — the north outshines the south because M104 inclines 6° to our line of sight.
