The Cygnus Wall of Star Formation
Explanation: The
North America nebula on the sky can do what the
North America continent on Earth cannot -- form stars. Specifically, in analogy to the Earth-confined continent, the bright part that appears as
Central America and
Mexico is actually a hot bed of gas, dust, and newly formed stars known as the
Cygnus Wall. The
above image shows the star forming wall
lit and eroded by
bright young stars, and partly hidden by the dark
dust they have created. The part of the
North America nebula (NGC 7000) shown spans about 15
light years and lies about 1,500 light years away toward the
constellation of the Swan (
Cygnus).
