AKA Grand Design spiral
Part of the Virgo cluster of galaxies, M100 is one of the brightest members of that group. It has two bright spiral arms and several fainter arms, similar to our Milky Way. M100 is almost face-on spiral that shows its young blue stars in the arms with over 100 billion stars. Visual magnitude is 9.3 and 56 million light years from earth.
This galaxy has a very bright central bar with diffuse outer arms. Some 9 million light years away, don't really have much more information on this guy. At this site is a much clearer image.
This face on galaxy is some 50 million light years from earth, located in the Virgo cluster (arn't they all?) A visual magnitude 10.0.
Found in the constellation Hercules. It was discovered by William Herschel on May 12, 1787, and first taken for a planetary nebula from his visual impression. A visual magnitude of 9.39. Herschel initially thought that it was a planetary nebula. It was only later that it was listed as a ' very crowded cluster. One of the reasons is that this cluster is some 100,000 light years from earth. The two are use to help identify it as part of a triangle.
ArcturusWhile we normally don't have images of stars, Arcturus is an exception. It is the brightest star in the constellation Bootis. A visual magnitude -0.05 ranks it as the 3rd brightest star in the night sky. Image was taken 14 June 2010, at the insistence of William "LittleBill" Becker-(from movie Unforgiven)
Arcturus is a K1.5Illpe orange giant star. It is considerably older than our Sun, but about 110 times more luminous. The 'Uplifted One' as it is also known, is 36.7 light years away and traveling towards us at 122 km/s. It may also be a binary star system but the jury is still out on that call.
This nebula is approx 5,200 light years from earth. Discovered by Le Gentil in 1747, then by Messier in on May 23, 1764. A stellar nursery where new stars are being formed from the150 light years wide worth of gas. It is in the constellation of Sagittarius. This nebula is second only to the Great Orion Nebula (M42). Its visual magnitued is listed as 6.
Rumor has it that this nebula was named after the sci-fic movie The Day of the Triffids, but that can't be confirmed. We do know that it was discovered by Le Gentil also in 1747. This nebula as well as M8 above are very close together. This diffused nebula is about 5,000 light years from earth. A fired up 7th magnitude star illuminates this nebula. Images will show the nebula's red, pink and blue colors.
Gobular Star Cluster
This gobular cluster is one of the closest if not the nearest cluster to earth at 7,000 light years. Located in the Scorpius constellation, it is one of the more 'mature' gobular clusters, as it is more yellow glow about it. Visual magnitude is 5.6. In 1995 Hubble revealed that M4 has white dwarfs stars that are 13 billion years some of the oldest in the Milky Way.
