General relativity doesn’t just bend light, it can influence planetary orbits enough to wipe out entire systems.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

In sum — what to know: Switching orbits: Starlink will re-orbit all its satellites operating at 550 km to 480 km from the Earth in 2026. Safety first: Michael Nicolls, VP of engineering at SpaceX, ...
