Pulsars and radio telescopes led NANOGrav researchers to a new kind of gravitational wave that emerges from colliding black holes.

Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe.

New Delhi, June 29 (IANS) Scientists have reported the first evidence that our Earth and the universe around us are awash in a background of spacetime undulations called gravitational waves.

Using part of the Milky Way as an antenna, researchers have found evidence for gravitational waves that undulate over periods of years to decades by measuring changes in the tick of ‘cosmic clocks.'

Astronomers have been able to “hear” the celestial hum of powerful gravitational waves, created by collisions between black holes, echoing across the universe for the first time.

A globe-spanning group of physicists used pulsars to measure the waves, which they believe emanated from pairs of supermassive black holes.

Scientists reported Wednesday that they were able to "hear" what are called low-frequency gravitational waves in space.

(CNN) — Astronomers have been able to “hear” the celestial hum of powerful gravitational waves, created by collisions between black holes, echoing across the universe for the first time.

"We're starting to open up this new window on the universe," one astrophysicist said.
