7 new Earth-like exoplanets discovered

Are humans alone in the universe?

NASA’s Spitzer Space Telescope has revealed SEVEN new planets in a newly discovered solar system which is 40 light years away from Earth.

Alien life may have evolved on at least three of the worlds orbiting a cool dwarf star known as TRAPPIST-1, located in the constellation Aquarius.

To celebrate the discovery, Google has a special Doodle by artist Nate Swinehart.

“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington.

“Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”
