The planet outside the solar system, dark, darker than a piece of coal, is found by astronomers. Jupiter is a planet orbiting its star at a distance of about five million miles, and the possibility of a temperature of 1200 degrees Celsius.
The planet is probably too hot to support reflective clouds as seen in the solar system. nnamun so it still can not explain why the planet is so dark. This study will be published in the Monthly Review press of the Royal Astronomical Society.
The planet, called TrES-2b are in the Transatlantic Exoplanet Survey in 2006. The distance from Earth at about 750 light-years away in the constellation Draco. The planet is in the space telescope Kepler in the order, with the aim of finding extrasolar planets using a measure of the light sensitive.
Using data for the first four months of Kepler, David Kipping, a researcher at the Center for Astrophysics at Harvard University and David Spiegel of Princeton University to evaluate the amount of light emitted directly from TrES-2b.
They measure the amount of light the "night side" of the planet, when directly in front of its star. Then compared with the light of the "dark side" before crossing the star.
The differences were then measured how much light is reflected or is called albedo.
In the solar system, Jupiter, clouds on the planet reflects light by 52%, 37% of the land reflects light. But it seems that the planet TrES-2b reflect the light beam is less than 1% of the star. "The albedo is darker than the acrylics or charcoal." Strange, "said Kipping told the BBC.
One explanation could be that the planet is too hot to support reflection clouds surrounding the planet as seen in the solar system. However, Kipping and Spiegel said it was not yet able to explain why TrES-2b as dark. Not only because the world does not reflect the rays of light, but is likely to absorb, he said.
