Just like the proverbial cat with nine lives, the notion of an unseen planet orbiting […]

New Dwarf Planet Candidate Discovered at Solar System's Edge: Could a Hidden Planet Be Orbiting Farther Out?

The discovery images of 2012 VP113. Three images of the night sky, each taken about two hours apart, were combined into one. The first image was artificially colored red, the second green, and the third blue. 2012 VP113 moved between each image as seen by the red, green, and blue dots. The background stars […]

Knocking On Hades' Door: T-Minus One Year Before NASA's 'New Horizons' Begins Encounter With Pluto
