...planet, called HD 189733b, revolves around a bright star 64 light years from Earth. Scientists refer to the planet as a "hot Jupiter" (it's similar to but slightly larger than Jupiter - and keeps a much tighter orbit around its sun, ensuring a scorching climate). And they have examined it for water before. But earlier tests of the planet's atmosphere yielded uncertain results, so this time, astrophysicists tried something slightly different. When HD 189733b was passing in front of its sun, they observed the way electromagnetic radiation was absorbed by the planet's atmosphere. The authors of the current...
...most of us back on Earth, the real significance will come when the technique is applied to other planets. "I agree we all have in the back of our brains that water is equivalent to life," says Tinetti. She doesn't believe HD 189733b itself will harbor life. That planet's surface temperature is an estimated 1,000 degrees K (more than 700 degrees C and 1,300 degrees F) on its sunny side, and scientists suspect it has very high winds - a hostile environment indeed. But if the technique to find water works on HD 189733b, then researchers...

Charbonneau said there could still be water on HD 189733b, but that dark clouds made of silicates in the planet’s atmosphere might make it impossible to see through...
