North America Nebula Burns Bright in Skywatcher Photo

The gas and dust of the North America Nebula glow pink and red in this skywatcher photo.

The North America Nebula lies in the constellation Cygnus, and it takes its name from a supposed resemblence to the continent. It is an emission nebula — essentially, a cloud of high-temperature gas emitting light of various colors.

The image was taken by Jean-Luc Dauvergne in August 2007 from the observatory at the Pic du Midi mountain in the French Pyrenees. The skyscape in the image glowing most brightly is the most active part of the nebula, a region astronomers call the Cygnus Wall. Here, hydrogen gas burns where new stars are forming.

The North America Nebula, also known as NGC 7000, is roughly 1,800 light-years away and perhaps 100 light-years in diameter. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers).

Pocket of Star Formation

This new view shows a stellar nursery called NGC 3324. It was taken using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. The intense ultraviolet radiation from several of NGC 3324’s hot young stars causes the gas cloud to glow with rich colours and has carved out a cavity in the surrounding gas and dust.

NGC 3324 is located in the southern constellation of Carina (The Keel, part of Jason’s ship the Argo) roughly 7500 light-years from Earth. It is on the northern outskirts of the chaotic environment of the Carina Nebula, which has been sculpted by many other pockets of star formation (eso0905).

A rich deposit of gas and dust in the NGC 3324 region fuelled a burst of starbirth there several millions of years ago and led to the creation of several hefty and very hot stars that are prominent in the new picture.
