Description

NGC 2992 is a Seyfert galaxy located 103 million light years distant in the equatorial constellation of Hydra. It was discovered in 1785 by Anglo-German astronomer William Herschel.

The nearby companion galaxy NGC 2993 is located less than 3′ to the southeast of NGC 2292. The two are linked by a tidal bridge of ionized hydrogen and there are tidal tails to the southeast of NGC 2993 and the north of NGC 2292. The encounter between these galaxies may be the trigger for the active nucleus in NGC 2992. There is a significant amount of dust obscuring the nucleus and cones of material outflowing from the core at nearly right angles to the alignment of the galaxy.
