Astronomers find a new way to detect gravitational waves

Researchers have found a new way to search for gravitational waves, the ripples in spacetime caused by massive celestial objects exploding, whirling, or merging. Physicists first sensed waves in 2015 with laser-based detectors, and other scientists have been chasing them with Earth-based radio telescopes. Now, the hunt has moved to space. A new study reveals that data from the Fermi Gamma-ray Space Telescope can, in theory, also sense a passing wave. Although the technique is not yet accurate enough to make an actual detection, it is already helping other researchers sharpen their analyses.
