Our universe may be filled with unseen giants. Astronomers have discovered two giant radio galaxies, which are some of the largest-known objects in the universe. This revelation suggests that the enormous galaxies may be more common than previously believed. The study published Monday in the Monthly Notices of the Royal Astronomical Society. Astronomers found the two galaxies in new...


  The Chang'e-5 robotic mission landed a few hours ago on lunar soil and aims to collect samples of rock and dust to bring them back to Earth.

Chalk up yet another win for Einstein. A twist in the fabric of spacetime is causing the orbit of one stellar corpse to teeter around another stellar corpse, researchers report. And the relativistic corkscrew is helping astronomers reconstruct the final days of these two long-dead stars. According to general relativity, any spinning mass drags spacetime around with it, like a hand mixer in...
