From Earth to the Universe: Picture of the day


ANT NEBULA

The Ant Nebula shows the typical bipolar shape of a planetary nebula when seen from the side. Planetary nebulae have nothing to do with planets; they just resembled planets when seen through early telescopes. Here a Sun-like star has shed material from its outer layers until its core is exposed, releasing powerful UV light that makes the gas glow. To obtain this view, astronomers used two space-based instruments - the Hubble Space Telescope (green and red) and the Chandra X-ray Observatory (blue).

In 2009, the "From Earth to the Universe" project brought astronomy to millions of people around the world. Take a tour of just some of the locations in a short video on the FETTU Highlights page.
