APOD 2.8 The Dark Tower In Scorpius

http://apod.nasa.gov/apod/ap130106.html

This picture shows a large, dark figure in the constellation of Scorpius. This evil looking figure is nearly 40 light years long and is known as a cometary globule. Certain parts of this figure are shaped by the constant bombardment of UV rays against it. To me, this was really interesting because I did not know that UV rays could actually shape something. The majority of this gas cloud is made from Hydrogen; we can tell because of its reddish color. The bright, blue orbs inside of the picture are the stars that can be found in Scorpius.
