A planet found in 2009 known as HAT-P-11b proven to host water recently. Found by Jonathan Fraine and his colleagues, its diameter is barely larger than 4 times the Earth's. Until recently, Neptune had been the only exoplanet to contain water. The temperature of the planet is roughly from 828° Kelvin to 928° Kelvin (1031° Fahrenheit to 1211° Fahrenheit). Its atmosphere's composition is primary hydrogen, hypothesized to have been drawn from nearby infant stars. Made primary of hydrogen the planet is found to have trace amounts of unidentified heavier elements. The atmosphere absorbs certain colors of light and filtering star light.

Deadly force against rocks



The US is stockpiling nuclear weapons to prevent asteroids from hitting the Earth when the time comes. Spending time envisioning such an event, the United Nations and NASA has an increasing favor towards nuclear  weapons. Stockpiling nuclear warheads, bombs, and more might seem useless to citizens, but not in the eyes of the UN. As stated in Wired.co.uk, Former NASA astronaut Ed Lu remarked that there are "100 times more asteroids lurking in space than have ever been located," and that our challenge is "to find them before they find us". A device called Sentinel Space Telescope (SST) is being created by the B612 Foundation, co-founded by Lu. A SST is a privately built infrared device allows the UN to accurately track asteroids on route to hit the Earth years ahead of time. The time estimated for the project to finish is told to be 2017.
