Description

Messier 77 (NGC 1068) is a face-on, barred spiral galaxy ~47 million light-years away in the constellation Cetus – imaged from dark skies in La Palma (Canary Islands) during my vacation.

NGC 1055 is an edge-on spiral galaxy at a distance of ~52 million light-years, that has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas.

Both galaxies form a binary system with a separation of 442,000 light-years and are the largest galaxies of a small galaxy group that also includes NGC 1073, and five other small irregular galaxies.

NGC 1072 is a small, 1.3 arcminute long and M 14.2 bright galaxy located at a distance of ~370 million light-years.
