Why TrES-2b is the darkest planet in the universe currently?

TrES-2b is the darkest planet in the universe according to scientists currently. It is also known for its other name, Kepler-1b. It is an Exoplanet which orbiting the star GSC 03549-02811. Star GSC 03549-02811, located 750 light years away from our solar system. TrES-2b or Kepler-1b is identified in 2011 as the darkest planet in the universe. Coal which is darkest is nothing in comparison to trEs-2b planet. It is very, very, extremely black. But still, scientists do not fully explain why TrEs-2b planet is extremely dark. TrES-2b, the darkest noted as exoplanet, reflective less light than coal or black paint. One reason can be that there is absence of reflective clouds like those that create Jupiter bright. TrES-2b's proximity to its parent star and also the resultant hot temperature. TrEs-2b planet absorbs 99% or more light that hits to it, and it is reflecting  one percent or small amount of any light that hits to it. According to mass and radius of it indicate that it is gas giant and gigantic planet like Jupiter. Mass and size of it is 1.5 times greater than Jupiter. TrEs-2b, orbiting very close to it's star. Distance between TrEs-2b planet orbits to its star is 3 million miles, that is why the temperature of TrEs-2b is 1885 degree Celsius. TrEs-2b planet belongs to the type of hot planets, that is why it is known as hot Jupiter. Atmosphere of trEs-2b planet is made up of titanium oxide, vaporized sodium, and potassium because of that things actually the compound problem by absorbing heat.



Discovery of TrEs-2b planet was in 21 August 2006. On September 8, 2006, W. M. Keck Observatory was confirmed the discovery of TrEs-2b planet. Trans-Atlantic Exoplanet Survey was discovered TrEs-2b planet. Trans-Atlantic Exoplanet Survey detects planets by the transit of planets across to it's star. Size of telescope is in 10 cm by which it detects planets. This telescope was made by using the network of small, it is relatively low cost telescope. This telescope located at Palomar Observatory which is located at Palomar mountain in the United States, Lowell Observatory which is located in Mars Hill Rd in the United States, and other Observatory, which is located at La Laguna, Santa Cruz de Tenerife, Spain. That all observatory know the location of exoplanets by transiting method. By using transiting method, it was made to look specifically for planets orbiting to its parent bright star.



On March 2009, NASA launched its Kepler's spacecraft, which discovered the exoplanets by transmit method. The First image was released in April  2009. In the above image two objects  highlighted, one is Tres-2b and its parent bright star by the spacecraft of Kepler. Kepler's spacecraft also detects the mass  of the planet from the curve of light of its parent star by analyzing. In the above image not only TrEs-2b planet, and its parent star can be detected, there are a lot of planets and its parent stars were detected.
