Water was not only exist on Earth. Scientists find signs of the existence of water vapor in the five exoplanets that is still located in the Milky Way galaxy. The five planets which found with the aid of the Wide Field Camera 3 on the Hubble Space Telescope. The existence of planets was revealed with the transit method, which analyzes the dimming of starlight when a planet passes in front of it.

While signs of water can be seen by examining the received wavelength. Water absorbs light at specific wavelengths so that the presence of water can be detected by looking at wavelengths that are not acceptable by Hubble.
The five planets that found each named WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b. All five are giant gas planets. Although they all have water, it does not mean that the planets can support life. The first is because they all are gas planets. Second, the planet is locked by gravity of its star. As a result, one of the planet's side will experienced the continuous daylight and the other vice versa.
The forever daylight side of the planet who have kept exposed by radiation from the star. Unfortunately, the radiation on one side of the planet is spread by the wind velocity exceeds the speed of sound. "The planets are very hard place," said L Drake Deming, an astronomer at the University of Maryland, who discovered these planets, as quoted by the LA Times, on Tuesday, December 3, 2013.
Presence of water or water vapor in those alien planets are actually not surprising. Scientists have discovered several planets that contain water. Going forward, there will be the James Webb Space Telescope, that will help scientists detect water on rocky planets. While Hubble is only able to detect water in the gas planets. *** [EKA | FROM VARIOUS SOURCES | LA TIMES | FIRSTPOST.]
