NGC 3314 [SEP] constellation
NGC 3314
NGC 3314 is a pair of overlapping spiral galaxies between 117 and 140 million light-years away in the constellation Hydra. This unique alignment gives astronomers the opportunity to measure the properties of interstellar dust in the face-on foreground galaxy (NGC 3314a). The dust appears dark against the background galaxy (NGC 3314b). Unlike interacting galaxies, the two components of NGC 3314 are physically unrelated. It was discovered in April 1999.
In a March 2000 observation of the galaxies, a prominent green star
arms of a spiral galaxy. The heretofore unexpected extent of dust beyond the starry limits of the arms shows new areas for extragalactic astronomical study. The dusty arms extend 6 times the radii of the starry arms of the galaxy, and are shown silhouetted in HST images against the central and core sections of the background galaxy.
