October’s Night Sky Notes: Let’s Go, LIGO! | Simple Site

by Kat Troche of the Astronomical Society of the Pacific September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert Einstein’s 1916 theory of General Relativity. These invisible ripples in space were first directly detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). Traveling at the speed of light […]
