Incredible Hulk? Nah, this glowing, green light in the night sky is a comet

A gigantic, green-tinged comet is currently smashing its way through the night sky, leading some people to dub it the "Incredible Hulk comet." Tomorrow (Aug. 7), the celestial object will make its closest approach to Earth, according to Sky and Telescope magazine. This is likely the first time the comet has ever come into the inner solar system.
