Object Info: Lying 7.000 light years distant in the next inner spiral arm of the Milky Way galaxy from us a great cloud of interstellar gas and dust has entered a vivid process of star formation. This stellar swarm is only about 5.5 million years old (according to the Sky Catalog 2000) with star formation still active in the Eagle Nebula; this results in the presence of very hot young stars. The size is about linear size of about 70x55 light years. Visual Brightness is 6.4 mag.
