NASA-funded Website Lets Public Search for New Nearby Worlds

NASA is inviting the public to help search for possible undiscovered worlds in the outer reaches of our solar system and in neighboring interstellar space. A new website, called Backyard Worlds: Planet 9, lets everyone participate in the search by viewing brief movies made from images captured by NASA's Wide-field Infrared Survey Explorer (WISE) mission. The movies highlight objects that have gradually moved across the sky.

Scientists Find Evidence of a Real Ninth Planet!

Scientists Find Evidence of a Real Ninth Planet!

Researchers from the California Institute of Technology  have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The newly discovered world, which the researchers have nicknamed Planet Nine, is extimated to be 10 times more massive than earth and 4 times its size. It orbits about 20 times farther from the sun on average than Neptune (which orbits the sun at an average distance of 2.8 billion miles). It would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun.
