Another Look at the Helix

Helix_VISTAESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) captured this unusual view of the Helix Nebula ( aka NGC 7293). The planetary nebula is labout 700 light-years away. This false color picture was created from images taken through three different infrared filters. The telescope’s infrared vision reveals cold nebular gas that is mostly obscured in visible images of the Helix.
