Stardust in Perseus
Explanation: This cosmic expanse of dust, gas, and stars covers some 6 degrees on the sky in the heroic constellation
Perseus. At upper left in
the gorgeous skyscape is the intriguing young star cluster
IC 348 and neighboring Flying Ghost Nebula. At right, another active star forming
region NGC 1333 is connected by dark and dusty tendrils on the outskirts of the giant
Perseus Molecular Cloud, about 850 light-years away. Other dusty nebulae are scattered around the field of view, along with the faint reddish glow of
hydrogen gas. In fact, the cosmic dust
tends to hide the newly formed stars and young stellar objects or protostars from prying optical telescopes. Collapsing due to
self-gravity, the
protostars form from the dense cores embedded in the dusty molecular cloud. At the molecular cloud's
estimated distance, this field of view would span almost 90 light-years.
