NGC 2606 is a spiral galaxy located around 646 million light-years away in the constellation Ursa Major. [2] [3] [4] NGC 2606 was discovered on February 16th, 1831 by the astronomer John Herschel, and it has a diameter around 232,000 light-years. [2] [1] [4] NGC 2606 is known to have some star-formation, and it is known to have an active galactic nucleus, specifically a Type II Seyfert galaxy. [2] [1]
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 3184, the Little Pinwheel Galaxy, is a spiral galaxy approximately 40 million light-years away in the constellation Ursa Major. Its name comes from its resemblance to the Pinwheel Galaxy. It was discovered on 18 March 1787 by German-British astronomer William Herschel. It has two HII regions named NGC 3180 and NGC 3181.
NGC 3877 is a type Sc spiral galaxy that was discovered by William Herschel on February 5, 1788. It is located below the magnitude 3.7 star Chi Ursae Majoris in Ursa Major.
NGC 4013 is an edge-on barred spiral galaxy about 55 million light-years away in the constellation Ursa Major. The disk of NGC 4013 shows a distinct "peanut"-shaped bulge in long exposure photographs that N-body computer simulations suggest is consistent with a stellar bar seen perpendicular to the line of sight.
NGC 3953 is a barred spiral galaxy located in the constellation Ursa Major. It was discovered by Pierre Méchain on 12 March 1781. 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 6251 is an active supergiant elliptical radio galaxy in the constellation Ursa Minor, and is more than 340 million light-years away from Earth. The galaxy has a Seyfert 2 active galactic nucleus, and is one of the most extreme examples of a Seyfert galaxy. This galaxy may be associated with gamma-ray source 3EG J1621+8203, which has high-energy gamma-ray emission. It is also noted for its one-sided radio jet—one of the brightest known—discovered in 1977. The supermassive black hole at the core has a mass of (5.9±2.0)×108 M☉.
NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. It is either a lenticular or spiral galaxy.
NGC 373 is an elliptical galaxy located around 204 million light-years away in the constellation Pisces. NGC 373 was discovered on December 12th, 1876 by John Louis Emil Dreyer. NGC 373 does not contain an active galactic nucleus, and it does not have much star formation.
NGC 3191 is a barred spiral galaxy in the constellation Ursa Major. It was discovered on 5 February 1788 by William Herschel. 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.
NGC 7541 is a barred spiral galaxy located around 104 million light-years away in the constellation Pisces. It was discovered in 1785 by William Herschel, and it is 106,000 light-years across. NGC 7541 is known to have lots of star-forming regions.
