This is one of the most colorful
areas in our galaxy. The image
was assembled as a mosaic
from 4 component images,
using the method outlined
here
by Rob Gendler.The bright blue
reflection nebula at the top, IC
4604,  is associated with the
triple star, Rho Ophiuchi.  
Antares (Alpha Scorpii), at the
bottom left, is surrounded by a
yellow area of nebulosity, IC
4606.  Antares literally means
"like Mars", due to its bright
yellowish-red color. Antares is
60,000 times brighter than our
sun, and is so large that its disc
can be easily measured -- if it
were in our solar system it
would almost reach to Jupiter!
The blue star towards the
middle is Sigma Scorpii, and is
surrounded by a red emission
nebula. Below Sigma Scorpii
and to the right of Antares is
the globular cluster, M4.
