Spiral Galaxy (Messier 81 (M81))

Distance away from us: 12 million light years away
-About 77% of the observed galaxies in the universe are spiral galaxies.
-Our own galaxy, the Milky Way, is a typical spiral galaxy.

Spiral Galaxy (The Sombrero Galaxy)
Distance away from us: 28 million light-years (8.6 Mpc) away
-The Sombrero has a central supermassive black hole at its heart. Observations of star motions near the black hole suggest it could have the mass of a billion Suns, perhaps the most massive of any black hole found so far at the heart of a galaxy.
-The galaxy has a diameter of approximately 50,000 light-years, 30% the size of the Milky Way.
