“Carbon Black World” indeed

Filed under: Carbon Black — Notch @ 12:19 am

Astronomers report the discovery of a distant planet in the constellation of Draco that is as black as coal, or pure carbon.

Like Jupiter, TrES-2b (discovered in 2006 by the Trans-Atlantic Exoplanet Survey or TrES, hence its name) is a gas giant. However, while “our” giant planet is covered by bright clouds of ammonia, which reflect more than one third of the light from the Sun, TrES-2b only returns less than one percent of that comes from its star. And this despite the fact that orbits it at least five million km., A fraction of the average distance between Jupiter and the Sun is 778 million km.

“TrES-2b is significantly less reflective than the black paint, which makes it a very strange world,” said David Kipping, of the Harvard-Smithsonian and author of the research to be published soon in Monthly Notices of the Royal Astronomical Society.
