This Hubble Space Telescope image of the lenticular galaxy NGC 6684 is dimly illuminated. Photographed by Hubble's Advanced Camera for Surveys, this galaxy is located about 44 million light-years from Earth in the constellation Pavo. Pavo, meaning "peacock" in Latin, is a constellation in the southern sky, one of the four constellations known as the Southern Birds.

Lenticular Galaxies

Although they lack the prominent spiral arms of the Andromeda Galaxy, the lenticular galaxies do have a large disk. One such lenticular galaxy is NGC 6684. This puts them somewhere between spiral and elliptical galaxies, giving these galaxies a hazy, eerie appearance. To further enhance its spectral appearance, NGC 6684 also lacks the black dust lanes passing through other galaxies.

The information used to create this image was collected as part of the local cosmos survey Every Known Local Galaxy, which is trying to study all galaxies within 10 megaparsecs (32,6 million light-years) that have not yet been observed by the telescope. About 75% of these neighboring galaxies were detected by Hubble before this program began. The results of this census will provide information about the stars that make up the various galaxies in various environments.
