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. ...
While similarly sized planets have been found before, the latest one, known as Kepler-452b, is circling a star that is very similar but older than the sun at a distance about the same as Earth’s orbit. “It’s great progress in finding a planet like Earth that is similar in size and...

In December 2011, two planets similar to the Earth were found - the Kepler-20e and the Kepler-22b. Kepler-20e, smaller than the Earth, orbits a Sun-like star slightly cooler and smaller than the Sun. But the surface temperature on the planet reaches 726 degrees Celsius, making the existen...
change that paradigm. The innovations that have gone into the instrument should make it possible to see planets similar to Jupiter in size and distance from their star. The Coronagraph team expects these advances will help enable the leap to viewing more Earth-like planets with future ...
planetary systems—also known as solar systems—containing more than one planet. And they have discovered some 4,000 planets. But even though humans have searched galaxies near and far for signs of life, the search mostly has found planets that are closer to their stars than Earth is to our...
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...
