At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...

NASA has known that the black hole at the center of the Perseus Galaxy creates sound since 2003. Scientists there have finally isolated the noise and shared it. It’s undeniably haunting but also a ...

On Sept. 14, 2015 astronomers “heard” two black holes crashing into each other at close to the speed of light. This discovery was a watershed moment in physics and astrophysics, heralding an entirely ...

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate “twinkle” — caused by rippling waves of gas on their surfaces ...

In this piece, you can actually listen to gravitational waves, the ripples in spacetime made by the tremendous mass of colliding black holes. It is possible to hear them, because their wavelengths ...

With scientists measuring energy waves traveling through stars and setting them to music, the familiar tune takes on a whole new meaning. When you purchase through links on our site, we may earn an ...

Plasma waves found traveling between Saturn, its rings, and its moon Enceladus have been turned into sound by NASA researchers. The waves were detected by the Cassini space probe during its final ...

When black holes gobble up the matter around them—often gas and dust from orbiting stars—they sometimes emit bursts of x-ray light that illuminate their edges. These bursts reverberate off of the ...
