The Southern Pinwheel Galaxy
NGC 7293, better known as the Helix nebula, is the nearest example of a planetary nebula, which is the eventual fate of a star, like our own Sun, as it approaches the end of its life. As it runs out of fuel, the star expels its outer envelope of gas outward to form a nebula like the Helix.

A Wide-field view of the Pencil Nebula
NGC 2736, also known as the Pencil Nebula, is located in the constellation Vela about 815 light-years away and is part the the Vela Supernova Remnant. This image of the region of sky around the Pencil Nebula shows a spectacular celestial landscape featuring the blue filaments of the Vela supernova remnant, the red glow of clouds of hydrogen and countless stars. It is a colour composite made from exposures from the Digitized Sky Survey 2.
