The VISTA telescope captured this unusual view of the Helix Nebula, a planetary nebula located 700 light-years away. 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.

The European Southern Observatory used its VISTA telescope in Chile to capture a view of the planetary nebula that is usually invisible to the human eye. The telescope's sensors are extremely sensitive to infrared light, which allowed it to pick up previously unknown strands of cold, thinly-spread gas.
This gas is mostly hidden in pictures taken in visible light, obscured by the bright blue glare of ultraviolet light from the Helix's hot central star. VISTA's images, however, reveal the nebula's delicate structure.
