Until now, our only source of gravitational waves has been binary star systems. Researchers from Northwestern University have potentially discovered a new non-binary source of gravitational waves ...

For an example of gravitational potential energy, consider a book placed on top of a table. To raise the book from the floor to the table, work must be done, and energy supplied.

A depiction of a dying star's cocoon (in yellow-green) surrounding a jet of energized material shooting out of a black hole (in red). Such cocoons are thought to be a new source of gravitational ...

But there were plenty of gravitational waves: Some of the mass of the two combined objects — amounting to about a fifth of the mass of our sun — was converted directly into energy, in ...

A pair of objects, each more massive than the Sun but only as wide as a city, have once again produced ripples in spacetime that were picked up by sensitive gravitational wave detectors on Earth ...

GCSE; CCEA Single Award; Energy forms - CCEA Higher tier: Gravitational potential energy. Energy cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

Although the first detection of gravitational waves in 2015 gets a lot of press, the detection of GW170817—the first binary neutron star collision—confirms how important gravitational waves ...

Gravitational waves reveal “mystery object” merging with a neutron star The so-called "mass gap" might be less empty than physicists previously thought.
