Researchers have discovered the first Earthsized planet. It was first marked by scientists using NASA’s Kepler telescope (望遠(yuǎn)鏡) ,so it’s called Kepler-186f. It lies about 500 light years from the Earth and goes around its star. The planet is the right distance from its star for water: not too close and not too far. Water is one important condition that scientists guess is necessary for life. So it could have water and possible life. It’s called a true Earth cousin.
“This planet is an Earth cousin,not an Earth twin ,” said Barclay,who is among a team of scientists reporting on the discovery in the magazine Science this week.
“It’s very exciting to find a planet similar to the Earth”’ Barclay said. “It’s not easy work because things change as we get more measurements. ”
Scientists don't know anything about the air of Kepler-186f,but it will be a task for future telescopes that can study for chemicals that have something to do with life.
“It’s possible for life to live on this planet,but that doesn’t mean there is life on it ,” Barclay said.
So far,scientists have found nearly 1 ,800 planets in the universe.
“The past year has seen a lot of progress in the search for Earthlike planets. Kepler-186f is very important because it is the first planet that is the same temperature and is almost the same size as the Earth ,” scientist David Charbonneau wrote in an email.
