Together with their sister group the Neandertals, Denisovans are the closest extinct relatives of currently living humans.
PASADENA, Calif. — Observations from NASA’s Voyager spacecraft, humanity’s farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.
