First planet discovered orbiting two suns nicknamed “Tatooine”


Even with two suns Kepler-16b is a cold, gaseous planet not believed to harbor life.

The Kepler Mission consists of a scientific NASA satellite called “Kepler” designed to discover Earth-size planets within our Milky Way galaxy.

New worlds are discovered when a planet crosses in front of its star as viewed by an observer, the event is called a transit. Transits by terrestrial planets produce a small change in a star’s brightness of about 1/10,000 (100 parts per million, ppm), lasting for 1 to 16 hours. This change must be periodic if it is caused by a planet.

Kepler-16b confirms the existence of a new class of planetary systems. This is especially important because most stars in our galaxy are part of a binary system. This discovery increases the chance of life on other planets.

Unlike its SyFy counterpart Tatooine, Kepler-16b is inhospitable, a cold planet as big as Saturn and believe to be made up of rock and gas. Nevertheless some scientists are beginning to informally call Kepler-16b, Tatooine.

Visual effects supervisor John Knoll of Industrial Light and Magic commented on the discovery saying, “It’s possible there’s a real Tatooine is out there.”

SpaceX, front-runner to replace retired NASA shuttles?

Space Exploration Technologies Corp., also known as SpaceX plans to send a rocket to the International Space Station.

The goal would be to send an unmanned Dragon space capsule on a test mission to the ISS and dock with the station. If successful the mission would bring SpaceX closer to a $1.6-billion contract with NASA.

“NASA has given us a Nov. 30, 2011, launch date, which should be followed nine days later by Dragon berthing at the ISS,” the company said.

If the mission is a success SpaceX would become the front-runner for shuttling cargo and astronauts to the space station for NASA.

The Dragon capsule and 18-story Falcon 9 rocket is built by SpaceX in an old fuselage assembly building in Hawthorne. The building was once used by Boeing Co.’s to assemble 747 jumbo jets.
