This is a four-image mosaic of The North America Nebula (also known as NGC 7000). It's an emission nebula, so-called because its shape resembles the North American continent, complete with a distinct Gulf of Mexico. Below and to the right is the upper portion of the Pelican Nebula (also known as IC 5070), part of the same nebula complex. Their distance is estimated to be about 1800 light years away.
