Astronomers have long turned their telescopes to the wide swaths of interstellar medium to get a look at the formation and birth of stars. However, the images produced over the last 50 years look more like weather maps showing storm systems instead of glittering bursts of light that the untrained observer might expect of a 'star map.' That is, until now.

Stardust in Perseus
more »
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.
