On April 1, astronomers will start two huge machines and continue hunting for ripples in space-time. One scientist gets his mom to translate news of each discovery into her native language, Blackfoot.

The original historical documents related to Albert Einstein's prediction of the existence of gravitational waves are seen at the Hebrew University in Jerusalem on Feb. 11, 2016.

Gravitational waves — ripples in the fabric of space-time — are a big deal in the world of science. Here's a video that helps explain how they work.

The collision of two neutron stars, seen in an artist's rendering, created both gravitational waves and gamma rays. Researchers used those signals to locate the event with optical telescopes.

In an astonishing discovery, astronomers used gravitational waves to locate two neutron stars smashing together. The collision created 200 Earth masses of pure gold, along with other elements.

The black holes were 14 and 8 times the mass of the sun. As they spiraled together, they sent out gravitational waves.
