Hubble finds three surprisingly dry exoplanets: ‘Hot Jupiters’ had only one-tenth to one one-thousandth the amount of water predicted

Astronomers have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the Sun — and have come up nearly dry. The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to be ideal candidates for detecting water vapor in their atmospheres because of their high temperatures where water turns into a measurable vapor.
