A spectacular tail stretches down for about 300,000 light-years from NGC 3628's warped, edge-on disk. Known as a tidal tail, the structure has been drawn out of the galaxy by gravitational tides during brief but violent past interactions with its large neighbors.
APOD: photo by Farmakopoulos Antonis; The California Nebula; Is in the Orion Arm of the Milky Way, as does our Sun, about 1500 ly distance. Also known as NGC 1499, is an emission nebula; The bright star to the right is most likely providing the starlight that ionizes much of the nebula's gas; located in Perseus, not far from the Pleiades.
#HelixNebula | 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 infrared filters. While bringing to light a rich background of stars and galaxies, the telescope's infrared vision also reveals strands of cold nebular gas that are mostly obscured in visible images of the Helix.
