![]() i win. Comments: This is indeed an authentic photograph — or rather, composite of photos — taken by NASA's Hubble Space Telescope and the Kitt Peak National Observatory in Arizona. It was featured on NASA's Website as an Astronomy Picture of the Day in May 2003 and thereafter posted on a number of Websites under the title "The Eye of God" (though I couldn't find evidence that NASA has ever referred to it as such). The awe-inspiring image has also been featured on magazine covers and in articles about space imagery. The image depicts the so-called Helix Nebula, described by astronomers as "a trillion-mile-long tunnel of glowing gases." At its center is dying, Sun-like star which has ejected masses of dust and gas to form tentacle-like filaments stretching toward an outer rim composed of the same material. The Sun itself may look like this in several billion years. Explanation: Will our Sun look like this one day? The Helix Nebula is the closest example of a planetary nebula created at the end of the life of a Sun-like star. The outer gasses of the star expelled into space appear from our vantage point as if we are looking down a helix. The remnant central stellar core, destined to become a white dwarf star, glows in light so energetic it causes the previously expelled gas to fluoresce. The Helix Nebula, given a technical designation of NGC 7293, lies about 650 light-years away towards the constellation of Aquarius and spans about 2.5 light-years. The above picture is a composite of newly released images from the ACS instrument on the Hubble Space Telescope and wide-angle images from the Mosaic Camera on the WIYN 0.9-m Telescope at Kitt Peak National Observatory. A close-up of the inner edge of the Helix Nebula shows complex gas knots of unknown origin. |
