A 50-million-light-year-long flow of hydrogen gas has been observed linking two tiny galaxies 50 million light-years away, giving astronomers a spectacular view of how galaxies attract, warp, and ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of science, technology, and medicine news ...

Gravitational-wave detection technology is poised to make a big leap forward thanks to an instrumentation advance led by physicist Jonathan Richardson of the University of California, Riverside. A ...

We previously covered one such “gravity telescope” with the Laser Interferometer Gravitational-Wave Observatory (LIGO). Another one is the Japanese project Kamioka Gravitational Wave Detector (KAGRA).

Today, we stand on sacred ground, not only for its pristine, radio-quiet skies, but for its role in uniting nations to ...

Einstein’s version of dark energy is known as the cosmological constant. It implies a fixed amount of dark energy in each ...

Abstract: Gravity inversion is the pioneer in exploring the structural characteristics of the Earth, the Moon, and other celestial bodies. Classical gravity inversion methods aim to estimate the 3-D ...

Ten years ago, astronomers made history when they first detected ripples in spacetime, called gravitational waves, from the ...

Scientists have captured the clearest signal yet of a black hole collision, confirming Stephen Hawking's theory.

In February 2004, a pair of workers attempted to roll an 800-pound reel of wire down some steps in the New York Stock Exchange using a crude rope sling. The reel tumbled forward, one of the workers ...

The LIGO confirmed predictions made by prominent physicists about black holes, as their nature could lead toward a theory of quantum gravity.

With the smoke cleared in the Black Canyon of the Gunnison, stargazers should, if the weather cooperates, enjoy perfect dark skies for the 2025 Black Canyon AstroFest next weekend. The event, which ...
