|| Discovered by William Herschel when the United States
was still in its infancy. This HUGE nebula is actually in the galaxy M33. It has a diameter
of 1500 light years and contains approximately 200 stars. Many of these stars have a mass
several times that of our sun. M33 is about 3 million light years away from Earth.
The bottom image shows the full frame- though it only represents a small
fraction of the galaxy M33.
