NGC 4244, the Silver Needle Galaxy in Canes Venatici389 viewsAnother "needle" edge-on galaxy, member of a group of galaxies associated with Messier 94 in the Virgo supercluster; about 14 million light-years from Earth.

NGC 6946 - Fireworks Galaxy and Friends387 viewsAn alternate view of the Fireworks Galaxy featuring a neighbor, the open star cluster NGC 6939, near the lower edge of the image.

Messier 100 and companions386 viewsSpiral Galaxy in the constellation Coma Berenices. Surrounded by tiny satellite galaxies NGC 4323 and NGC 4328 (about 3 o'clock and 5:30). Larger spiral galaxy at top is NGC 4312.

Markarian's Chain of Galaxies384 viewsA chain of galaxies in the Virgo Cluster, named after a Soviet astronomer. Right to left: M84, M86, NGC 4477, NGC 4473, NGC4461, NGC 4458, NGC4438 and NGC4435.

NGC 891- Silver Sliver Galaxy382 viewsAn edge-on spiral galaxy in Andromeda; about 30 million light-years distant; similar in size to the Milky Way.

Messier 101 - The Pinwheel Galaxy381 viewsFace-on spiral galaxy in the constellation Ursa Major. A colossus among galaxies, 170,000 light-years across (Milky Way is 105,700), with a trillion stars. Distance - approx. 25 million light-years from Earth.

NGC4565 - The Needle Galaxy376 viewsGigantic edge-on spiral galaxy in Coma Berenices, twice as luminous as the Andromeda Galaxy. 40 million light-years from Earth. Satellite galaxy NGC 4562 is shown at lower right.

M51- The Whirlpool Galaxy361 viewsThere are actually two interacting galaxies here; the smaller companion is NGC 5195, and the two have collided in the past, causing all kinds of woe and grief. They are about 25 million light years away.

NGC 7331 - Spiral Galaxy in Pegasus341 viewsAbout 40 million light-years away; similar in size and structure to the Milky Way.

Messier 81 and 82327 viewsThese two galaxies are found in the constellation Ursa Major and are about 12 million light-years away. The larger one, M81, is also known as Bode's Nebula; the smaller is known as the Cigar Galaxy, although it's a funny kind of cigar because it looks like it's lit in the center rather than at one end. Maybe it's an exploding cigar. Yes - that's it! It's a starburst galaxy, with an abnormally high rate of star formation in the center!

Messier 63 - The Sunflower Galaxy314 viewsAt a distance of 37 million light-years in the constellation Canes Venatici, M63 is known as the Sunflower Galaxy because of its bright yellow core (not so obvious in this image). At 98,000 light-years diameter, in is similar in size to the Milky Way.
