the European Southern Observatory (ESO) in the Atacama desert houses the
world's most powerful telescope, the Very Large Telescope or VLT. It comprises
four telescopes each weighing 22 tons, and through their combined strength it
is possible to see small objects on the moon and larger features far out in space.
The Observatory stands on Cerro Paranal, 2600m above sea level, where the skies
are clear almost every night of the year.
