NGC 1550 is a lenticular galaxy located in the constellation Taurus. NGC 1550 was discovered by the German-British astronomer William Herschel in 1785.[3] NGC 1550 was also observed by the Prussian astronomer Heinrich d'Arrest on December 29, 1861 and was added to the New General Catalogue under the designation NGC 1551.[3]
Characteristics
Its speed relative to the cosmic microwave background is 3,633 ± 18 km/s, which corresponds to a Hubble distance of 53.6 ± 3.8 Mpc.[1]
A measurement not based on redshift gives a distance of 83,500 Mpc.[4]
NGC 1550 group
The NGC 1550 group is a galaxy group that contains eight galaxies: NGC 1550, NGC 1542, UGC 2994, UGC 2998, UGC 3002, UGC 3004, UGC 3010 and PGC 14744. Of these galaxies, NGC 1550 is the brightest.[5]
In 2020, observations from Chandra suggested that galaxies in the NGC 1550 group are heated by active galactic nuclei.[6]
