ALMA gegenschein
On the Chajnantor plateau in Chile, home of the Atacama Large Millimetre/submillimetre Array (ALMA), the sky is so dark that the famous and extremely difficult to observe gegenschein (or "countershine") is sometimes visible.
This is a faint brightening of the night sky in the region of the ecliptic directly opposite the Sun, caused by reflection of sunlight by interplanetary dust in the Solar System.
