North is to the
top.
The North America
Nebula in the sky can do what most North Americans 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. This monochrome skyscape shows the star
forming wall lit and eroded by bright young stars, and partly hidden
by the dark dust they have created. The North America Nebula (NGC
7000) spans about 50 light years and lies about 1,500 light years
away toward the constellation of the Swan (Cygnus).
