M13-20110501c.jpg
Messier 13 - Hercules Globular Cluster412 views145 light-years in diameter, consisting of several hundred thousand stars, this is the most famous globular cluster in the Northern Hemisphere and is about 22,000 miles from Earth.Jun 19, 2019
M106-20170420.jpg
Messier 106 and companions455 viewsThe large spiral galaxy at left is M106, lying at a distance of 22 to 25 million light-years from Earth in the constellation Canes Venatici. A myriad of other galaxies are in the frame, of which the two most prominent are NGC 4248 (closest to M106) and NGC 4217 (disk at right).Jun 19, 2019
M104-20150418.jpg
Messier 104 - The Sombrero Galaxy601 views28 million light-years away in the constellation Virgo, the Sombrero is one of the most spectacular of all galaxies.Jun 19, 2019
M101-201704.jpg
Messier 101 - The Pinwheel Galaxy427 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.Jun 19, 2019
M100-20130511c.jpg
Messier 100 and companions428 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.Jun 19, 2019
M63-20170429.jpg
Messier 63 - The Sunflower Galaxy367 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.Jun 19, 2019
M81-M82-20140222.jpg
Messier 81 and 82377 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!Jun 19, 2019
NGC1499-20151107.jpg
NGC 1499 - The California Nebula456 viewsAn emission nebula in the constellation Perseus, so called because it resembles the State of California in shape (though not in this image). About 1000 light-years from Earth.Jun 17, 2019
M42-20141129.jpg
M42 - The Great Nebula in Orion473 views1344 light-years away, 24 light-years across, this emission/reflection nebula is one of the brightest in the sky, as well as the closest region of massive star formation to Earth. Jun 17, 2019
M20-20150816.jpg
M20 - The Trifid Nebula553 viewsA combination of an open cluster of stars, an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (which accounts for the gaps dividing the nebula into lobes). About 5000 light-years away in the constellation Sagittarius.Jun 17, 2019
M51-20130407c.jpg
M51- The Whirlpool Galaxy398 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.Jun 17, 2019
M33-20160930.jpg
M33 - The Triangulum Galaxy471 viewsAbout 3 million light-years away, this is the third-largest member of the Local Group, which includes M31 and the Milky Way.Jun 17, 2019
