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. [3] [4]
The Type IIn supernova SN 1998S [3] [5] is the only supernova that has been observed within NGC 3877.
NGC 3877 is a member of the M109 Group, a group of galaxies located in the constellation Ursa Major that may contain over 50 galaxies. The brightest galaxy in the group is the spiral galaxy M109. [6] [7] [8]
Messier 95, also known as M95 or NGC 3351, is a barred spiral galaxy about 33 million light-years away in the zodiac constellation Leo. It was discovered by Pierre Méchain in 1781, and catalogued by compatriot Charles Messier four days later. In 2012 its most recent supernova was discovered.
Messier 96 is an intermediate spiral galaxy about 31 million light-years away in the constellation Leo.
Messier 109 is a barred spiral galaxy exhibiting a weak inner ring structure around the central bar approximately 67.2 ± 23 million light-years away in the northern constellation Ursa Major. M109 can be seen south-east of the star Phecda.
NGC 3982, also known as UGC 6918, is an intermediate spiral galaxy approximately 68 million light-years away in the constellation Ursa Major. It was discovered by William Herschel on April 14, 1789, and misclassified as a planetary nebula. NGC 3982 is a part of the M109 Group.
NGC 3184, the Little Pinwheel Galaxy, is a spiral galaxy approximately 40 million light-years away in the constellation Ursa Major. It has two HII regions named NGC 3180 and NGC 3181.
NGC 3949 is an unbarred spiral galaxy in the constellation Ursa Major. It is believed to be approximately 50 million light-years away from the Earth. NGC 3949 is a member of the M109 Group, a group of galaxies located in the constellation Ursa Major that may contain over 50 galaxies. The brightest galaxy in the group is the spiral galaxy M109.
NGC 4088 is an intermediate spiral galaxy in the constellation Ursa Major. The galaxy forms a physical pair with NGC 4085, which is located 11′ away.
NGC 6744 is an intermediate spiral galaxy about 30 million light-years away in the constellation Pavo (Peacock). It is considered as a Milky Way mimic in the immediate vicinity, displaying flocculent (fluffy) arms and an elongated core. It also has at least one distorted companion galaxy superficially similar to one of the Magellanic Clouds. It was discovered from Parramatta in Australia by Scottish astronomer James Dunlop on 30 June 1826.
NGC 4027 is a barred spiral galaxy approximately 83 million light-years away in the constellation Corvus. It is also a peculiar galaxy because one of its spiral arms goes out more than the other. This is probably due to a galactic collision in NGC 4027's past.
NGC 3953 is a barred spiral galaxy located in the constellation Ursa Major. The galaxy is known to exhibit an inner ring structure that encircles the bar. NGC 3953 is a member of the M109 Group, a large group of galaxies located within the constellation Ursa Major that may contain over 50 galaxies.
NGC 4559 is an intermediate spiral galaxy with a weak inner ring structure in the constellation Coma Berenices. Distance estimates for NGC 4559 range from about 28 million light-years to 31 million light-years, averaging about 29 million light-years.
NGC 2082 is an intermediate spiral galaxy in the Dorado constellation. It was originally thought to be part of the Dorado Group of galaxies, but was later removed. It was discovered on November 30, 1834 by John Herschel.
NGC 3191 is a barred spiral galaxy in the constellation Ursa Major. It is located at a distance of about 400 million light years from Earth, which, given its apparent dimensions, means that NGC 3191 is about 115,000 light years across. The galaxy has been distorted and interacts with a companion 1.3 arcminutes to the west. An extremely blue tidal bridge lies between them.
ESO 269-57 is a large spiral galaxy located about 150 million light-years away in the constellation Centaurus. ESO 269-57 has a diameter of about 200,000 light-years. It is part of group of galaxies known as LGG 342. which is also known as the NGC 5064 Group which is part of the Centaurus Supercluster.
NGC 668 is a spiral galaxy located 200 million light-years away in the constellation Andromeda. It was discovered by astronomer Édouard Stephan on December 4, 1880 and is a member of Abell 262.
NGC 669 is an edge-on spiral galaxy with an active galactic nucleus located 200 million light-years away in the constellation Triangulum. NGC 669 was discovered by astronomer Édouard Stephan on November 28, 1883 and is a member of Abell 262.
NGC 705 is a lenticular galaxy located 240 million light-years away in the constellation Andromeda. The galaxy was discovered by astronomer William Herschel on September 21, 1786 and is also a member of Abell 262.
NGC 753 is a spiral galaxy located 220 million light-years away in the constellation Andromeda. The galaxy was discovered by astronomer by Heinrich d'Arrest on September 16, 1865 and is a member of Abell 262.
NGC 759 is an elliptical galaxy located 230 million light-years away in the constellation Andromeda. NGC 759 was discovered by astronomer by Heinrich d'Arrest on September 17, 1865. It is a member of Abell 262.
NGC 694 is a spiral galaxy approximately 136 million light-years away from Earth in the constellation of Aries. It was discovered by German astronomer Heinrich Louis d'Arrest on December 2, 1861 with the 11-inch refractor at Copenhagen.
