Image details:

This trio of galaxies is located in the northern constellation of Draco.
NGC 5981 is a edge-on spiral , NGC 5982 a elliptical galaxy , and NGC 5985 is a face-on spiral. While the group is far too small to be a galaxy cluster and has not been catalogued as a compact group, these galaxies all do lie roughly 100 million light-years from planet Earth. On close examination with spectrographs, the bright core of the striking face-on spiral NGC 5985 shows prominent emission in specific wavelengths of light, prompting astronomers to classify it as a Seyfert, a type of active galaxy. Not as well known as other tight groupings of galaxies, the contrast in visual appearance makes this triplet an attractive subject for astrophotographers . (Information from NASA)
