Scientists appear to have evidence of water on a planet outside our Solar System.
The planet is called HD 189733b and orbits a star in the constellation of Vulpecula the Fox.
The international team, which included scientists from University College London, took measurements of the planet's absorption parameters. They did painstaking calculations to show that the absorption pattern observed could only be explained by the presence of water vapor in the atmosphere.
Although the planet has water on it, it is far from being habitable-parts of the atmosphere reach 2,000 degrees.
These results show, however, that water might be more common on other planets than previously thought, and that the method used by these scientists can be used in the future to study other environments-environments that may be more amenable to life.
The findings are published in the latest issue of Nature. Read more in this press release.
