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.
