Chinese team finds key evidence for low-frequency gravitational waves with FAST telescope

A Chinese team has found key evidence of low-frequency gravitational waves, which are ripples of space-time that could provide clues to some of our universe’s darkest secrets.

Using the Five-hundred-metre Aperture Spherical Telescope (FAST) in Guizhou, the Chinese Pulsar Timing Array (CPTA) team spent more than three years tracking 57 exotic stars known as pulsars in the Milky Way galaxy in order to catch the tiny ripples.
