Hubble Discovers A Blue Alien World
HD 189733b is an exoplanet that has just made it into the history books. For the first time ever, astronomers have been able to determine the true color of a planet orbiting another star. The results are spectacular. If you were to get a good look at HD 189733b, which lies just 63 light years away, you would discover that it has a beautiful deep blue color.
Using the NASA/ESA Hubble telescope, the team of astronomers were able to measure the changes in the color of the planet's light emissions during various phases of orbit around its star. They noted that as the planet passed behind its star, levels of blue light dropped, but the green and red levels stayed relatively stable. Likewise, when the planet reemerged from behind its star, levels of blue light increased just as significantly. These observations led The University of Exeter's Frederic Pont and his team to the conclusion that the exoplanet was undoubtedly a deep blue in color.
HD 189733b may look beautiful, but you certainly wouldn't want to visit it. The gas giant hosts winds of around 4,500mph and temperatures of up to 2000 degrees fahrenheit.
