It’s official. There’s something out there shaking the stars in a way that can no longer be ascribed to chance.

Several teams around the world have independently found a signal in the timing of flashing stars called pulsars that points to giant, long-wavelength gravitational waves rolling through the galaxy. It’s not quite a detection of those gravitational waves yet – but there is more than a 99 percent chance that what we’re looking at is something significant.

Teams in Australia, the US, Europe, China, and India are releasing their results simultaneously in a slew of papers.
