Sobre North America Nebula
Descrição
The North America Nebula (NGC 7000) is a large emission nebula in Cygnus, about 2,590 light-years away. Spanning over 2 degrees (four full Moons), its shape remarkably resembles the continent of North America, complete with a Gulf of Mexico and Atlantic coast.
Dicas de Observação
Too large for most telescopes — best in binoculars or a wide-field instrument at lowest power. Requires very dark skies to see the outline. An H-beta or UHC filter can help. Naked-eye visible from excellent dark sites as a brighter patch in the Milky Way near Deneb. Best in summer and autumn.
História
First photographed by Max Wolf in 1890. William Herschel observed the region but the nebula's full shape was not appreciated until photographic surveys. Its illuminating star remained unknown until 2005 when it was identified as the O5 star 2MASS J205551.25+435224.6.
Curiosidades
The dark Gulf of Mexico region is actually a foreground dust cloud called the Cygnus Wall. The North America Nebula and the adjacent Pelican Nebula (IC 5070) are actually parts of the same enormous HII region separated by this intervening dust.
