This comparison shows a stunning view of the 30 trillion-km-wide Helix Nebula acquired with the VISTA #telescope in infrared light along with a more familiar view in visible light from the #ESO 2.2-metre telescope. The infrared vision of VISTA reveals strands of cold nebular gas that are much less prominent in visible light images of the Helix.
