W33 is the name of the light which is enlightened in this amazingly beautiful picture captured by NASA's Spitzer telescope. The large starry zone is located close to the skyline of the galaxy, which is 13,000 light years away from the Earth.
The yellow color in the picture shows that this is the initial stage of the star formation of this region. Its diameter is about 100 light years.
