The Swift telescope has charted a star's plunge into a supermassive black hole at the core of a distant galaxy
Researchers measured the intensity of the universe's ultraviolet background radiation, and say it may be strong enough to strip small galaxies of star-forming gas. Christopher Intagliata reports.
Eyeing a potential lander in the 2030s, scientists are studying the icy moon's treacherous surface
Hidden, impermanent balances in nature have shaped the history of physics, and could determine our universe’s future
Researchers used ancient climate cycles to confirm the solar system’s chaotic planetary orbits. An Earth–Mars collision is one distant outcome. Julia Rosen reports.
