Description Billions of years ago, an hours-long Martian sandstorm blew so intensely that sand ripples began to climb upon one another as they moved across the surface. These layers of sediment eventually hardened into the multilayered rocks seen in this image, which was taken by

Engineers have developed a new way to monitor how tiny lab-grown human heart tissues beat—by effectively "listening" to the ripples they create. The team has created a wireless, noninvasive sensing platform that can biomechanically measure how strongly the miniature heart tissues

For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to ripples in space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound world is a super-Jupiter orbiting far f

This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical chemist and the original spark for this research, Ge

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits gravitational waves—ripples in the fabric of spacetime—
