Stardust in the Perseus Molecular Cloud

Explanation: Clouds of stardust drift through this deep skyscape,
across the Perseus molecular cloud some 850 light-years away. Dusty
nebulae reflecting light from embedded young stars stand out in the
nearly 2 degree wide telescopic field of view. With a characteristic
bluish color reflection nebula NGC 1333 is at center, vdB 13 at top
right, with rare yellowish reflection nebula vdB 12 near the top of the
frame. Stars are forming in the molecular cloud, though most are
obscured at visible wavelengths by the pervasive dust. Still, hints of
contrasting red emission from Herbig-Haro objects, the jets and shocked
glowing gas emanating from recently formed stars, are evident in NGC
1333. The chaotic environment may be similar to one in which our own
Sun formed over 4.5 billion years ago. At the estimated distance of the
Perseus molecular cloud, this cosmic scene would span about 40
light-years.
