NGC281 - The Pac-Man Nebula263 viewsA bright emission nebula, part of an H II region in the constellation Cassiopeia; known as the Pac-Man Nebula because of its resemblance to the video game character that flits around ruthlessly and insatiably chomping up defenseless, pathetic little dots.Aug 03, 2022
NGC7635_20210905_LHaRGB1~0.jpg
NGC7635 - The Bubble Nebula - H-alpha enhanced version263 viewsAn emission nebula in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a hot, massive star within a molecular cloud which contains the expansion of the bubble, preventing it from dissipating, and is also itself excited by the star. The nebula is 7 light years across and 7100 light-years away.Aug 03, 2022
NGC7293-20140921-LRGB2.jpg
NGC 7293 - The Helix Nebula in Aquarius257 viewsOne of the closest planetary nebulae, at only 650 light-years from Earth. Around 10,600 years old and 2.5 light-years in diameter. Sometimes known as the "Eye of God" or the "Eye of Sauron."Aug 02, 2022
M11_20220702_RGB1.jpg
M11 - The Wild Duck Cluster300 viewsOne of the richest, most compact and most massive open clusters known; estimates range from 3,700 to 11,000 solar masses. Radius 95 light-years. 6,120 light-years away, in the constellation Scutum. Supposedly the cluster resembles a flying flock of ducks, although as far as I can tell it could just as well be geese, crows or magpies.Aug 02, 2022
NGC4565_20150412_LRGB2.jpg
NGC4565 - The Needle Galaxy203 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.Aug 01, 2022
M64_20210409_LRGB3_v1.jpg
M64 - the Black-eye Galaxy260 viewsA relatively isolated spiral galaxy 17 million light-years away in the northern constellation Coma Berenices. A dark band of absorbing dust partially in front of its bright nucleus inspires its "Black Eye" nickname.Aug 01, 2022
M85-20210416-LRGB2.jpg
M85 - Lenticular or Elliptical Galaxy in Coma Berenices219 viewsM85 is a lenticular galaxy in the process of transitioning to an elliptical galaxy. It lies on the outskirts of the Virgo Cluster and is 60 million light-years away, is estimated to be 125,000 light-years across, and is interacting with the smaller nearby galaxy NGC 4394.Aug 01, 2022
M83-20210403-LRGB2.jpg
M83 - The Southern Pinwheel Galaxy233 viewsA barred spiral galaxy about 15 million light-years away in Hydra, on the border with Centaurus. The nickname derives from its resemblance to the Northern Pinwheel Galaxy, M101.Aug 01, 2022
M74-20161102.jpg
M74 - Spiral galaxy in Pisces217 viewsFace-on spiral galaxy about 32 million light-years from Earth in the constellation Pisces.Aug 01, 2022
M66_20150320_LRGB1A.jpg
The Leo Galaxy Trio266 viewsA famous triplet of spiral galaxies: Lower right - Messier 66; upper right, Messier 65; lower left, NGC 3628. All about 35 million light years away in the constellation Leo the Lion.May 26, 2022
NGC6207_20220522_LRGB1C.jpg
NGC 6207, Spiral Galaxy in Hercules224 viewsNGC 6207 is the small oval object on the right side of the photo, just below the centerline. It is seen nearly edge-on and is about 30 million light-years from Earth. It is somewhat outshone by M13, the large globular cluster on the left, which is of course much closer, at 22,200 light-years from Earth. May 24, 2022
20220514-NGC4244_LRGB2C.jpg
NGC 4244, the Silver Needle Galaxy in Canes Venatici230 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.May 24, 2022
