32.Which of the following statements is TRUE about the newly found planets?___A.It will take human beings about 40years to travel to themB.Some of them might have the proper conditions to support lifeC.They are spread out in the habitable zone around Trappist-1D.Underground ice has been...
suggestion is to limit the search for life-supporting planets to Earth-sized bodies orbiting single, sun-like stars in their habitable zones. I realize this cuts way down on the number of possible candidate planets and there is also the fact that such planets are much much more difficult to...

Astronomers say they are on the point of finding planets like Earth orbiting other stars, which is a key step in determining if we are alone in the universe. A top NASA official and other leading scientists say that within four or five years they should

根据文章第二段Earth is the only known planet that stays in a perfect position from our Sun to support water in a liquid state.Astronomers call this perfect distance from a star the "habitable (宜居的)" or "Goldilocks zone".(地球是已知的唯一一颗距离太阳很近的行星,...
