  • Astronomers detect orbital motion in pair of supermassive black holes
    Images made with the continent-wide Very Long Baseline Array detect the orbital motion of two supermassive black holes as they circle each other at the center of a distant galaxy. The two black holes themselves may eventually merge in an event that would produce gravitational waves that ripple across the universe.
  • Topsy-turvy motion creates light switch effect at Uranus
    Uranus' magnetosphere, the region defined by the planet's magnetic field and the material trapped inside it, gets flipped on and off like a light switch every day as it rotates along with the planet, scientists have discovered. It's 'open' in one orientation, allowing solar wind to flow into the magnetosphere; it later closes, forming a […]
