A pair of NASA space telescopes have captured a spectacular new photo of the Helix Nebula, a glowing celestial vision that resembles a giant cosmic eye. The Helix Nebula (also known as NGC 7293) represents a dying star known as a planetary nebula. The new picture, released Wednesday, combines data from NASA's Spitzer Space Telescope, which observes in long-wavelength infrared light, and the Galaxy Evolution Explorer (GALEX), which picked out the short-wavelength ultraviolet light coming from the object. The Helix Nebula is located about 650 light-years from Earth in the constellation of Aquarius. It provides a sneak peak at the future of our own sun, which is expected to turn into a planetary nebula in about 5 billion years. Planetary nebulas aren't planets at all, but they were erroneously named in the 18th century because they resembled gas giant planets, and the name has stuck.
