Cloze - Another solar system

Ever since the discovery of a new solar system several weeks ago, scientists have been ____________ whether planets in the system could ____________ life. Scientists called the system "TRAPPIST-1". It ___________ a small sun and seven Earth-sized planets. It _______ very similar to our own solar system. NASA scientist Michael Gillon said three of the seven TRAPPIST-1 planets receive as much heat from its sun as Venus, Earth and Mars from our Sun. He said this _________ the right environment for life to _________ . TRAPPIST-1 is in a star system called Aquarius. It _________ nearly 40 light-years away from the Earth. Its sun is smaller than our Sun and has just 1/1000th of its brightness, but that could _________ enough to life.

Michael Gillon _________ that you could ________ the other six planets in the sky if you ________ on one of the TRAPPIST-1 planets. A neighbouring planet could __________ bigger than our view of our Moon. Mr Gillon said: "If you _________ on the surface of one of these planets, you would _________ a wonderful view of the other planets. You wouldn't ___________ them like we see Venus or Mars, like dots of light. You would see them really as we see the Moon. You would see the structures on these worlds." Astronomer Dr Jessie Christiansen said life ______ everywhere, "such as bacteria that survives in 130-degree caves, or things at the bottom of the ocean where there's no light". She said it could ____________ possible for life to __________ on some of these planets.
