Color of the New Planet Blue

Astronomers for the first time have come to the reasonable conclusion of the color of a planet outside our solar system. The planet, HD 189733b and discovered in 2005, belongs to a family known as the "Hot Jupiters" that revolve close to their stars, and has a daytime temperature of around 1,800 degree Fahrenheit and has wind speed of 4,500 mph. Although the earth also looks blue from the space because of our oceans, this planet--HD 189733b--looks blue because of silicate particles in the atmosphere that scatter blue color off the light. Scientists have used Hubble Space Telescope to determine the color of the planet. Dr. Frederic Pont of the University of Exeter in England has said on July 12, 2013: "Measuring the planet's color is the real first--we have never managed it before with a planet outside our own solar system".
