This
color composite image of nearby NGC 300 combines the visible-light pictures
from Carnegie Institution of Washington's 100-inch telescope at Las Campanas
Observatory (colored red and yellow), with ultraviolet views from NASA's Galaxy
Evolution Explorer. Galaxy Evolution Explorer detectors image far ultraviolet
light (colored blue).
This
composite image traces star formation in progress. Young hot blue stars
dominate the outer spiral arms of the galaxy, while the older stars congregate
in the nuclear regions which appear yellow-green. Gases heated by hot young
stars and shocks due to winds from massive stars and supernova explosions
appear in pink, as revealed by the visible-light image of the galaxy.
Located
nearly 7 million light years away, NGC 300 is a member of a nearby group of
galaxies known as the Sculptor Group. It is a spiral galaxy like our own Milky
Way.
