The other main named star in Hydra is Sigma Hydrae (σ Hydrae), which also has the name of Minchir, [8] from the Arabic for snake's nose. At magnitude 4.54, it is rather dim. The head of the snake corresponds to the Āshleshā Nakshatra, the lunar zodiacal constellation in Indian astronomy. The name of Nakshatra (Ashlesha) became the proper ...
NGC 3242 (also known as the Ghost of Jupiter, Eye Nebula or Caldwell 59) is a planetary nebula located in the constellation Hydra.. William Herschel discovered the nebula on February 7, 1785, and catalogued it as H IV.27.
NGC 3936 is a barred spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,357 ± 24 km/s, which corresponds to a Hubble distance of 34.76 ± 2.46 Mpc (∼113 million light-years). [1] It was discovered by British astronomer John Herschel on 24 March 1835. [2]
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]
NGC 2835 is an intermediate spiral galaxy located in the constellation Hydra. It is located at a distance of circa 35 million light years from Earth, which, given its apparent dimensions, means that NGC 2835 is about 65,000 light years across. It was discovered by Wilhelm Tempel on April 13, 1884. [3]
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 5495 is a very large barred spiral galaxy located in the constellation Hydra. [1] [2] Its speed relative to the cosmic microwave background is 6,989 ± 20 km/s, which corresponds to a Hubble distance of 103.1 ± 7.2 Mpc (∼336 million ly). [3] [4] NGC 5495 was discovered by British astronomer John Herschel in 1834.
NGC 2935 is a large intermediate spiral galaxy located in the constellation Hydra. Its speed relative to the cosmic microwave background is 2,601 ± 23 km/s, which corresponds to a Hubble distance of 38.4 ± 2.7 Mpc (~125 million ly). It was discovered by German-British astronomer William Herschel on 20 March 1786. [1] [2]
