In Chile, Searching for Alien Life in the Sky

With its clear sky and dry air, Chile's Atacama desert is a place where astronomers1 look up at the night skies for life on other planets. They also study dark energy, a mysterious force thought to be driving the growth of the universe.

Soon, they will have a new Giant Magellan Telescope (GMT) to search into distant worlds beyond Earth. The GMT is a $1.8 billion center being built at the Las Campanas observatory2. The telescope will be able to see 10 times clearer than the well-known Hubble space telescope.

The GMT is expected to begin operating by 2030. It will compete with the nearby European Southern Observatory's Extremely Large Telescope as well as the Thirty Meter Telescope being built in Hawaii.

Leopoldo Infante is the head of the Las Campanas observatory. He said the new generation of giant telescopes is being developed to search for life on other planets and look for the origin of dark energy. "It's a race by these three groups for who makes it first and who makes the first discovery," he said.

Infante said the new large telescope would be able to find molecules3 in the atmosphere of faraway planets. "And whoever detects life on another planet will win the Nobel Prize, I assure you."

The other prize is studying dark energy which makes up most of the universe. Infante said dark energy is causing the universe to expand but scientists do not understand its origin.

Infante said the GMT will help astronomers study and understand "what that energy is and where that energy comes from."
