The Helix nebula is one of the closer planetary nebula created by the death throes of a star much like our own Sun. The remnant of the star, a white dwarf, glows and causes the material previously expelled to fluoresce. The Helix is 700 light-years distant in the constellation Aquarius and spans 2.5 light-years. Its age is estimated to be ~12,000 years and the material is moving away from the center at ~32 km/s. If you zoom in on the image you can see that he inner ring contains radially symmetric knots of nebulosity each of which is about the size of our solar system. The Helix contains about 20,000 of these cometary knots. L(Ha/Oiii)RGB 13 Hours/Ha 3 Hours/Oiii 4 Hours/RGB
