This intriguing trio of galaxies is sometimes called the Draco Group, located in
the northern constellation of (you guessed it) Draco. From left to
right are edge-on spiral NGC 5981, elliptical galaxy NGC 5982, and face-on spiral NGC 5985 -- all within this single
telescopic field of view spanning a little more than half the width of the full
moon. 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. This
impressively
deep exposure hints at faint, sharp-edged shells surrounding elliptical NGC
5982, evidence of past galactic mergers. It also reveals many even more distant
background
galaxies.
