  • Chaotic Comet Collisions around Star Suggest Presence of Unknown Planet

    A puzzling build-up of carbon monoxide around the nearby star Beta Pictoris revealed to astronomers a stellar phenomenon: the splattered remains of comets colliding together around the star. The researchers believe they are observing this cosmic comet destruction in real-time at a rate of one comet per five minutes, and that it may be caused by an unknown planet in orbit around the star.
