NGC 3200 is a large spiral galaxy located in the constellation Hydra. Its velocity relative to the cosmic microwave background is 3,877 ± 25 km/s, which corresponds to a Hubble distance of 57.2 ± 4.0 Mpc (~187 million ly). NGC 3200 was discovered by American astronomer Edward Singleton Holden in 1882. [1]
Hydra has one bright binary star, Epsilon Hydrae, which is difficult to split in amateur telescopes; it has a period of 1000 years and is 135 light-years from Earth. [7] The primary is a yellow star of magnitude 3.4 and the secondary is a blue star of magnitude 6.7. However, there are several dimmer double stars and binary stars in Hydra.
NGC 3336 is a barred spiral galaxy [2] [3] located about 190 million light-years away [4] in the constellation Hydra. [2] It was discovered by astronomer John Herschel on March 24, 1835. [5] [3] NGC 3336 is a member of the Hydra Cluster. [6] One supernova has been observed in NGC 3336: SN 1984S (type unknown, mag. 16.8) was discovered by Paul ...
NGC 5135 is a barred spiral galaxy located in the constellation Hydra. It is located at a distance of about 200 million light years from Earth. It was discovered by John Herschel on May 8, 1834. [ 2 ]
NGC 2617 is a Seyfert galaxy in the equatorial constellation of Hydra. It was discovered on February 12, 1885, by French astronomer Édouard Stephan. [7] [8] In 1888, Danish astronomer J. L. E. Dreyer described it as "extremely faint, very small, 2 very faint stars involved". [9] It is located at an estimated distance of 202 million light years ...
NGC 2848 is an intermediate spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,361 ± 23 km/s, which corresponds to a Hubble distance of 34.82 ± 2.46 Mpc (∼114 million light-years). [1] It was discovered by German-British astronomer William Herschel on 31 December 1785.
NGC 4993 (also catalogued as NGC 4994 in the New General Catalogue) is a lenticular galaxy [5] located about 140 million light-years away [2] in the constellation Hydra. [6] It was discovered on 26 March 1789 [7] by William Herschel [6] [7] and is a member of the NGC 4993 Group. [3]
NGC 2936, also known as the Penguin Galaxy or the Porpoise Galaxy, is an interacting spiral galaxy located at a distance of 326 million light years, [3] in the constellation Hydra. NGC 2936 is interacting with elliptical galaxy NGC 2937, located just beneath it. They were both discovered by Albert Marth on Mar 3, 1864. [4]
