It's the first time astronomers have determined the color of a planet outside the solar system.
An international team of astronomers working with the Hubble Telescope made the discovery observing HD 189733B, one of Earth's nearest planets outside the solar system. The gas giant has a temperature of 2,000-degrees. Scientists say it may rain glass- sideways- on this planet amid 4,500 mph winds.
HD 189733B is 63 light years away.
Frederic Pont of the University of Exeter in England said Friday that "measuring the planet's color is a real first - we have never managed it before with a planet outside our own solar system."
To ascertain the planet's color the astronomers measured the amount of light reflected off its surface as it eclipsed its host star.
