Water vapour detected on alien world
http://space.newscientist.com/articl...ter-found-on-a
n-alien-world.html Water has been detected in the atmosphere of an alien world for the first time, a new analysis of Hubble Space Telescope data suggests. Some scientists applaud the result - which had been predicted theoretically but not observed in previous studies, while others say the apparent water signal may simply be instrumental noise. The planet, called HD 209458b, is about 70% as massive as Jupiter and is scorched by the heat of its parent star, which it orbits 9 times as close as Mercury does to the Sun. |

... which it orbits 9 times as close as Mercury does to the Sun. Nine times as close is a weird construct. Does it mean at one ninth the distance? -- Remove "antispam" and ".invalid" for e-mail address.
