April - VISTA’s look at the Helix Nebula
ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) has captured this unusual view of the Helix Nebula (NGC 7293), a planetary nebula located 700 light-years away. The coloured picture was created from images taken through Y, J and K infra- red filters. While bringing to light a rich back- ground of stars and galaxies, the telescope’s infrared vision also reveals strands of cold nebular gas that are mostly obscured in visi- ble images of the Helix.
