NGC5907-800-240x10.jpg

NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth.[2] It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars.[3] It is a member of the NGC 5866 Group. NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. Then in 2006, an international team of astronomers announced the presence of an extended tidal stream surrounding the galaxy that challenges th

NGC3432-1600-60x20.jpg

Edge-on spiral in Leo Minor. NGC 3432 or Arp 206 was catalogued by Halton Arp as a galaxy with "material ejected from the nuclei." The disruption is presumably caused by interaction with UGC 5983, the dwarf galaxy to the southwest of NGC 3432. Redshift data gives a distance of 12 +/- 0.9 Mpc for the main galaxy and 14 +/- 1 Mpc for the interacting galaxy.

M51-1600-240x5.jpg 2015-04-20

The Whirlpool Galaxy (also known as Messier 51a, M51a, or NGC 5194) is an interacting[7] grand-design[8] spiral galaxy with a Seyfert 2 active galactic nucleus[9] in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy.[10] Recently it was estimated to be 23 ± 4 million light-years from the Milky Way,[3] but different methods yield distances between 15 and 35 million ly. Messier 51 is one of the best known galaxies in the sky.

Messier 66 (also known as NGC 3627) is an intermediate spiral galaxy about 36 million light-years away in the constellation Leo. It was discovered by Charles Messier in 1780. M66 is about 95 thousand light-years across[3] with striking dust lanes and bright star clusters along sweeping spiral arms.[4] M66 is part of the famous Leo Triplet, a small group of galaxies that also includes M65 and NGC 3628.

NGC5033-1600-240.jpg

NGC 5033 is an inclined spiral galaxy located in the constellation Canes Venatici. Distance estimates vary from between 38 to 60 million light years from the Milky Way Galaxy. The galaxy has a very bright nucleus and a relatively faint disk. Significant warping is visible in the southern half of the disk. The galaxy's relatively large angular size and relatively high surface brightness make it an object that can be viewed and imaged by amateur astronomers.

NGC4435 & NGC4438.jpg

The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. This galaxy takes its name from its ring structure which made it popular. NGC 4435 is a barred lenticular galaxy with a relatively young (age of 190 million years) stellar population on its central regions that has been discovered by the Spitzer Space Telescope and whose origin may be the interaction with NGC 4438.[1]

NGC4111-1600-240x5.jpg

NGC 4111 is a spiral galaxy located roughly 50 million light-years away in the constellation of Canes Venatici. It is part of the Ursa Major South Group of galaxies, which is comprised of at least 32 large galaxies. Note galaxy at top and 2 further galaxies at bottom of page.

NGC3893-1600-300x4.jpg 2015-04-20

NGC3893/3896 is an M51-type interacting galaxy pair seen in the direction of the Constellation Ursa Major around 50 Million Light-Years distant. NGC3893 is a spiral galaxy, type Sc and NGC3896 appears to be a lenticular galaxy. There is a bridge of gas, dust and stars faintly seen between the two The pair has been studied for dark matter interaction and rotation characteristics between the two.

NGC3877-1600-240x5.jpg 2015-04-20

NGC 3877 is a type Sc spiral galaxy that was discovered by William Herschel on February 5, 1788.[3] It is located below the magnitude 3.7 star Chi Ursae Majoris in Ursa Major.

NGC3628-1600-60x16.jpg 2015-04-20

NGC 3628, also known as Sarah's Galaxy,[3][4] is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. NGC 3628 along with M65 and M66 form the famous Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to our view.

NGC 891 (also known as Caldwell 23) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster. It has an H II nucleus.[3] The object is visible in small to moderate size telescopes as a faint elongated smear of light with a dust lane visible in larger apertures. In 1999, the Hubble Space Telescope imaged NGC 89

M106-1600-240x5.jpg 2015-04020

Messier 106 (also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center.
