NASA's Hubble Space Telescope has allowed astronomers who have been making visible-light observations to detect the true color of a faraway alien world for the first time. The exoplanet, HD 189733b, is 63 light-years away from Earth, which makes it one of the nearest exoplanets that can be seen crossing the face of its star. It has been referred to as the deep blue dot for its deep cobalt blue color and has an exotic atmosphere. HD 189733b has a daytime temperature of around 2,000 degrees Fahrenheit and has violent storms of glass rain and 4,500 mph winds.
