New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One ...

The extrasolar planet or " exoplanet " in question is TOI-2109b, which has five times the mass of Jupiter and is located ...

For instance, there was a chance that antimatter could be repelled by gravity rather than attracted – meaning it would fall ...

Scientists predict up to 100 invisible galaxies may orbit the Milky Way, hiding just beyond our current detection limits.

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe.

They often twirl around heavier ones, like our Milky Way, as satellite dancers. The dark matter distribution of a Milky Way ...

Scientists say they have found a mysterious 'tiny world' in our solar system. Apparently, the Subaru Telescope at the Mauna Kea Observatory in Hawaii has uncovered there's a new 380-kilometer world ...

Scientists demonstrate that quantum networks of clocks offer a new way to explore the interplay between quantum mechanics and curved space-time. Quantum networking is advancing rapidly across the ...

In 1919, a total solar eclipse allowed scientists to confirm Einstein’s theory of general relativity by observing how the sun’s gravity bent starlight. This discovery revolutionized physics and made ...

A team of scientists led by expert Raúl Jiménez, ICREA researcher at the University of Barcelona's Institute of Cosmos ...

Instead of the big bang, some physicists have suggested that our universe may have come from a big bounce following another ...
