Black hole week reaches its conclusion today (May 10), and there's no better way to mark the occasion than with some "eggs-traordinary" black hole science.
Using gravitational wave measurements by the Laser Interferometer Gravitational-Wave Observatory (LIGO), based in the U.S., and the Virgo and KAGRA detectors, located in Italy and Japan, respectively, scientists have found that the orbits of some binary black holes could be egg-shaped and exhibit a curious wobble.
