Citizen scientists can examine photos to help discover a new planet, which recent evidence suggests is hiding at the edge of the solar system
Back in 2012, as the day purportedly foretold by the Mayan calendar as the end of the world came closer, the internet lit up with pseudo-science theories that the Earth was destined to crash into Planet X—aka Niburu—a hidden shadow planet lurking in our solar system. That, luckily, didn’t happen (Niburu-truthers now have now recscheduled the crash for October 2017), but in recent years scientists have discovered real evidence of a hidden planet. And now they are asking the science-minded public to help them scan the skies for it.
