One of the enduring mysteries of space science is the matter of our tilting sun. For decades now, scientists have known that the sun's spin axis is about six degrees off-vertical - but no one knew why. Until now. Newly published research appears to have finally solved the enigma, as space science producer Ian O'Neill explains in today's DNews dispatch.
The new discovery explains a lot of things, actually, and suggests that a previously unknown celestial body is tweaking the motion of the sun, all the other planets, and literally everything else in our solar system. Check out Ian's report for further details on the mysterious Planet 9 from outer space.
