It is the stuff that many astrophysicists dream about: While gazing into their telescope, they discover an Earth-like planet, or they learn more about the origins of galaxies, the possibility of extraterrestrial life and the mysterious dark energy.
With the ELT, the European Southern Observatory (ESO) is on a path to creating a new mega-telescope for more advanced space research. It is currently being built on Cerro Armazones (10,049 feet), a mountain in Chile.
