Paranal sky with comet

The illuminated dome of the Residencia at ESO's Paranal Observatory in Chile produces no light pollution to impede the work of the telescopes. Above, the magical arc of the Milky Way spans the sky. To the left, near the horizon, is the comet 252P/LINEAR, which made only its fifth closest approach to the Earth in recorded history on 22–23 March 2016. This wonderful image was taken during ESO's Fulldome Expedition to Chile, a team of photographers collecting spectacular images for use in planetarium presentations.
