Good old Hubble stroke gold again, or should I say blue. NASA's famous space telescope, or its imaging spectograph detected the planet HD 189733b to be of a true blue color. This is what Frederic Pont of University of Exter in South West England described the find: "We saw the light becoming less bright in the blue but not in the green or red. Light was missing in the blue but not in the red when it was hidden. This means that the object that disappeared was blue."
HD 189733b is quite a strange planet, belonging to class of planets we call hot Jupiters. Characteristic for hot Jupiters is the tend to orbit dangerously close to their parent star which orbit precariously close to their parent stars. The observations yield new insights into the chemical composition and cloud structure of the entire class.
HD 189733b was discovered in 2005. It orbits only 2.9 million miles close to its parent star, which is close enough for the gravity to be locked. Another distinguish feature of is that one side always faces the star and the other side is always dark
