We still don’t have any idea what the planets look like, or if water in any form actually exists on them. Still, filtering out the most likely life-supporting planets is a huge step towards potentially confirming extraterrestrial life one day, and that’s still pretty exciting. Tech. ...

NASA hasfound new evidenceof 219 planets outside our Solar System. Ten of those exoplanets appear to be similar to the size of the Earth and orbit their stars in thehabitable zone— just far enough away to develop water, but not so far that they freeze. If confirmed, they would be adde...
Another study using Kepler data suggested two distinct size groupings of small planets: rocky Earth-like bodies and gaseous planets smaller than Jupiter. Few planets were found between those groupings. "We like to think of this study as classifying planets in the same way that biologists identify...
“Answering the question ‘are we alone’ is a top science priority,” he said. “And finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.” The new discovery set the record for the most habitable-zone planets found ar...
have reportedly found a new solar system (which orbits a star known as TRAPPIST-1, which is 8 percent the size of the sun) with a number of planets that look like Earth, act like Earth, and probably call themselves "New Earth" behind our backs. Hell, NASA calls it a new record. ...
分析句子结构可知,“ has been named Earth 2.0”为定语从句,先行词是 Kepler 452b,且从句中缺少主语,所以引导词选用 which。句意:被命名为地球2.0的开普勒452b已经有60亿年的历史了。故答案为:which。like 解析:考查介词。结合句意可知,此处指“它和地球是如此像”,所以橫线处需要填入介词 like,表示“像”。句...
