A planet without an atmosphere bolsters concerns about bodies orbiting stars smaller than the sun
Most of the terrestrial planets in the galaxy orbit stars smaller than the sun. Because of their sheer numbers, they would seem to be promising candidates in the search for life elsewhere. But astronomers say they suspect that these bodies—especially ones in close orbit—are vulnerable to losing their atmospheres, necessary to support life. The discovery of one such planet beyond the solar system with no atmosphere at all clouds the prospects for its peers.
