夏说英语新闻晨读 第212期:科学家发现7颗类地行星

 本期内容：

Astronomers¹ discovered seven planets, roughly Earth-sized, orbiting a dwarf² star some 380trn kilometers from our own. That is 40 light years away—fairly close and within range of planned big telescopes. Scientists therefore think it offers the best chance yet to discover evidence of life, or why it hasn’t evolved, beyond the solar system.
