NGC-7000. Commonly called "The North American Nebula" due to its shape, NGC-7000 is a vast cloud of hydrogen gas and interstellar dust. It lies 2600 light years from Earth and is 140 X 90 light years in extent. It is located just east of the "tail" of Cygnus, the Swan, approximately 3 degrees east of the 1st magnitude star Deneb (Alpha Cygni). The North American Nebula was discovered visually by Sir William Herschel in October of 1786. He described it as "a faint milky nebulosity scattered over this space".
