A nebula is a mixed cloud of dust and gas which appears as a haze spread across the sky when it is viewed through a telescope. IC5067, which is also known as the "Pelican Nebula" is an example of an emission nebula (which is just one of four types of nebula: emission, planetary, reflection, and dark). This emission nebula is lit by a bright, massive star on the other side of the gas relative to our location. As the light passes through the thin atomic hydrogen gas (against a cool background), it lights up to show the bright spectacle of red gas that we see. The sharp edges contrasted in the middle of the nebula are formed by solar winds in space that push the gases around. Another example of an emission nebula is the massive North American Nebula (NGC 7000).
IC 5067 is the smaller branch of the very large Pelican Nebula and is known as the 'neck' of the Pelican. The larger part of the nebula is known as IC5070 and features a more dense & brighter array of red gas. The Pelican Nebula (IC5067 & 5070) lie between about 1800 & 2000 light years away in the Cygnus the Swan constellation. The total diameter of the nebula spans about 15 light years across. The dark, defined edges on the right side of the red hydrogen gas is a dust field that is in front of the gas. This dust blocks out the light from the star that is illuminating the gas.
