A curious tilt in our solar system has led researchers to believe that there may be a massive, hidden ninth planet lurking just past Neptune. by California Institute of Technology (Caltech) scientists Konstantin Batygin and Mike Brown, according to a release. The planets in our solar system orbit in a flat plane, roughly within a couple degrees of each other and with respect to the sun. However, the plane rotates at a six-degree tilt that makes it seem as though...

At a Glance Several Facebook pages have recently broadcast old videos of spacewalks and passed them off as brand-new.In reality, there hasn't been a single spacewalk since Sept. 1. Over the years, there has been no shortage of suggestions that space events are hoaxes, and those claims are usually disproven quickly. But a sudden rash of Facebook Live broadcasts showing spacewalks at the International Space Station didn't really happen – at least not recently –and debunkers have been hard at...

At a Glance A computer program being developed by NASA will act as an asteroid intruder alert.The program, Scout, detects Near Earth Objects and calculates the potential risk. Scout detected a possible threat this month. The possibility of an asteroid colliding with the Earth is a threat that scientists have become increasingly interested in avoiding. A computer program called Scout is helping them keep an eye out. Scout is essentially to determine if there are any reports of Near Earth...
