NASA and the European Space Agency have revealed that astronomers have achieved a feat by determining the true color of a planet outside our solar system. The planet is named as HD 189733b. It is a deep blue planet, and orbiting a star 63 light years away.

The gas giant has the daytime temperature that soars to 2,000 degrees Fahrenheit. The most interesting thing is that it rains liquid glass sideways through hypersonic, 7,000km-per-hour winds.

The deep azure light is a result of small drops of glass scattered in its atmosphere. NASA said, "A hazy, blow-torched atmosphere containing high clouds laced with silicate particles. Silicates condensing in the heat could form very small drops of glass that scatter blue light more than red light".

The planet was observed by the researchers before, during and after it passed its star while orbiting. When the planet emerged on either side of its star, the whole system brightened. But when the planet moved behind its star, the brightness of the system dropped sharply in the blue part of the spectrum.

The findings will enable the astronomers to figure out which exoplanet might be habitable. HD 189733b is classified in the category of planets called hot Jupiters.
