NGC 1052 is an elliptical galaxy in the constellation Cetus.

Features

NGC 1052 is located at a distance of around 63 million light years from the Milky Way,[2] and has a LINER-type active galactic nucleus which signals the intense starburst activity in the galaxy's center[3] that were confirmed with observations with better resolution showing a number of star-forming regions and young star clusters.[4]

NGC 1052 shows also two small jets emerging from its nucleus as well as a very extended disc of neutral hydrogen, far larger than the galaxy itself,[5] all these features suggesting a gas-rich galaxy collided and merged with it 1 billion years ago producing all the above features.[4]
