NGC 281 Pacman Nebula


NGC 281 is a busy workshop of star formation. Prominent features include a small open cluster of stars, a diffuse red-glowing emission nebula, large lanes of obscuring gas and dust, and dense knots of dust and gas in which stars may still be forming. The open cluster of stars IC 1590 visible around the center has formed only in the last few million years. The brightest member of this cluster is actually a multiple-star system shining light that helps ionize the nebula's gas, causing the red glow visible throughout. The lanes of dust visible left of center are likely homes of future star formation. Particularly striking in the above photograph are the dark Bok globules visible against the bright nebula. The NGC 281 system, dubbed the Pacman nebula for its overall shape, lies about 10 thousand light years distant.

LDN 673


 At a distance of about 600 light years from us, LDN 673 is a beautiful dark nebula covering almost a full degree of sky in the constellation of Aquila. The nebula is superimposed upon the thick molecular clouds within the Milky Way. The dust in these molecular clouds scatters the blue light from these stars, giving the surrounding stars a decidedly yellow-red bias.

Barnard 138

 

In this photo we see a curved, dark marking, B 138, finally ending in a sharp, black spot. The curved object looks like a great, black lizard. Its head is the sharply defined black spot, B 139.  The "lizard" even has legs, one of which is a sharp, dark projection, B 137.

Pleiades Star Cluster (Seven Sisters or M45)

 



Hurtling through a cosmic dust cloud some 400 light-years away, the lovely Pleiades or Seven Sisters star cluster is well-known for its striking blue reflection nebulae. In the dusty sky toward the constellation Taurus and the Orion Arm of our Milky Way Galaxy, this remarkable image shows the famous star cluster in the middle.

Milky Way around Sagittarius

 

Sagittarius lies in the direction of the densest part of the Milky Way, the spiral galaxy in which our Solar System resides. If it were not for interstellar dust, which is concentrated along the plane of the Milky Way, this constellation and those near it would be obscured by the brilliance of the galactic core. The field of view near the galactic center is heavily mottled with stars and interstellar matter. In addition, several large fuzzy patches of light are clearly visible.

Rho Ophiuchi cloud complex

 

Near the star Rho Ophiuchi, in the extreme southwest corner of Ophiuchus, is a region of strangeness and beauty. The star itself is enmeshed in a vast diffuse nebulosity, IC 4604, too faint to be studied visually. But from this nebulous region a number of dark narrow lanes flow out toward the east, appearing like black tentacles obscuring the starry background. These vacant lanes end near the star Xi Ophiuchi. Near Xi also is the large and strangely shaped dark cloud B63. This is an extraordinary region, described by Barnard as making a picture almost unequalled in interest in the entire heavens.
