The first hint of what will become of our Sun was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. --http://apod.nasa.gov/apod/ap111227.html

NGC 5189 Physicists say we are made of stardust. Intergalactic debris and far-flung atoms, shards of carbon nanomatter rounded up by gravity to circle the sun. As atoms pass through an eternal revolving door of possible form, energy and mass dance in fluid relationship. We are man, we are thought, we are story. We are all star stuff.
This shock wave plows through space at over 500,000 kilometers per hour. Moving right to left in the beautifully detailed color composite, the thin, braided filaments are actually long ripples in a sheet of glowing gas seen almost edge on. Cataloged as NGC 2736, its narrow appearance suggests its popular name, the Pencil Nebula.
NGC 6302 (The Butterfly Nebula): With an estimated surface temperature of about 250,000 degrees C, the central star of this particular planetary nebula is exceptionally hot -- shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust. This dramatically detailed close-up of the dying star's nebula was recorded by the newly upgraded Hubble Space Telescope. Credit: NASA, ESA, and the Hubble SM4 ERO Team
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 of 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.
