Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave ...

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one ...

For the first time, astronomers have managed to weigh a planet that is not bound to any star, a lonely world drifting through ...

The coordinate system used by GPS is WGS 84, which expresses altitudes as a "height above ellipsoid". Because this ellipsoid is a mathematical simplification, the height given by GPS does not ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

Capturing the first image of a supermassive black hole using the Event Horizon Telescope (EHT). This image of the black hole at the center of the nearby galaxy M87 reveals how gravitation affects the ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...
