Description

I think this is one of the roughest broadband objects I have ever processed in my red zone. It is small and very faint.

NGC 3227 and NGC 3226 in Leo are a pair of colliding spiral galaxies 50,000,000 light-years distant, which were discovered by John Herschel. Also classified by Halton Arp as Arp 94. The larger face-on galaxy on the left, NGC 3227, is an unbarred SAB(s) pec(uliar) spiral, while the smaller galaxy on the right, NGC 3226, is a dwarf elliptical. The interaction between the two galaxies is visible as spectacular loops, arcs, and star streams that are the remnants of an ongoing gravitational dance between the two. Both galaxies' nuclei are considered AGN (active galactic nucleus), while NGC 3227's is a Seyfert-type nucleus, with variable X-ray emission. It also likely contains a supermassive black hole.
