The Opportunity rover on Mars fell silent on June 10th following a massive dust storm on the Red Planet. Now, as the storm begins to clear, NASA officials hope to once again hear from the intrepid robotic explorer. The space agency will listen in for 45 days after the storm clears, hoping to receive a signal. The spacecraft landed on Mars in 2004, and has been exploring the alien landscape for nearly 15 years.Read More The Plan to Rescue the Opportunity Rover from a Deep Slumber on Mars
Planet Nine could exist at the most distant reaches of our solar system, according to observations of the orbits of far-flung objects. This theoretical world would be 10 times as massive as Earth, and take between 10 and 20,000 years to orbit the Sun. However, such a planet would be so dark and distant that some astronomers speculate it may be 1,000 years before we discover it.Read More Is Planet Nine Hiding at the Edge of the Solar System?
