On Thursday, June 28, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) revealed the detection of low-frequency gravitational waves, a historic breakthrough that ...

Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for ...

The universe is continuously rippling with gravitational waves, a 15-year survey has reported. Using pulsars as distant beacons and radio telescopes to plumb the galaxy, a massive collaboration of ...

Cosmic lighthouses as gravitational wave detectors . To detect the gravitational wave background, astronomers studied fast-spinning stars called millisecond pulsars, which are dead stars that spin ...

Today, a humongous team of astronomers called the NANOGrav Collaboration announced something remarkable: the first evidence for a background hum of gravitational waves that permeates our universe ...

The unit of frequency of an EM wave — one cycle per second — is called a hertz, in his honor, according to the American Association for the Advancement of Science. Bands of radio waves.

The frequency and intensity of past cyclones are determined by geologically dating and topographically surveying these features, then running numerical models that estimate surge and wave heights ...

A 0.5 Hz ultrasound frequency has a wavelength of over 600 microns. Human cells size from a few microns up to about 150 microns, all which are too small to exhibit internal resonance with a sound ...
