NGC 1055 (edge on spiral upper left) and M77 (face on spiral at lower right) are located about 50 million light years away in the constellation of Cetus. Both galaxies belong to the same cluster of galaxies, and these two are thought to be separated a mere 500,000 light years.

M77 is a Seyfert type II Galaxy. Seyferts are characterised by a brilliant starlike nucleus, fainter spiral arms, and specific emission spectra from their nucleus. Although they appear a relatively normal luminosity at visible wavelengths, a Seyfert Type II galaxy such as this is about 100 times more luminous at radio, x-ray and infrared wavelengths than other galaxies.
