Snake Nebula Region: This is a region of gas and dust which obscures the light from the rich starfields "behind" the gas and dust, toward the center of our galaxy. The twisted part in the middle of the frame is known as the "Snake Nebula." The Snake Nebula is estimated to be about 650 light years away from us, which would make the field of this photo about 40 light years across.
