2.6 Stardust in Perseus

In the constellation Perseus, this cloud of dust covers nearly 4 degrees on the sky. NGC 1333 is in the center of the picture, colored a dusty blue. It rests some 1,000 light-years away. At that distance, the field of view is estimated to be 70 light-years across, a truly massive distance. Several dark dust nebulae as well as the reddish glow of Hydrogen gas can be seen on the outskirts of the dust cloud.
