NGC 2444 is a peculiar lenticular galaxy in the constellation Lynx.

The galaxy lies about 135 million light years away from Earth, which means, given its apparent dimensions, that NGC 2444 is approximately 50,000 light years across.

As a result of the collision, a bridge of young blue stars has formed between the two galaxies, and while the galaxy itself has been stretched, NGC 2444 contains old stars and no new starbirth because it lost its gas long ago, well before this galactic encounter.

The supernova occurred between the two galaxies, about 3.5 arcseconds away from a HII region of NGC 2445.

The pair is part of a galaxy group known as LGG 148.
