A broad low in Earth’s gravity field beneath Antarctica, known as the Antarctic geoid low, is not a sudden oddity. New reconstructions suggest it has persisted for about 70 million years and has been ...

We’re going back to the moon. Well, at least that’s the hope.

Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

As space agencies prepare for human missions to the moon and Mars, scientists need to understand how the absence of gravity affects living cells. Now, a team of researchers has built a rugged, ...

“Quantum sensing opens an entirely new domain for U.S. space leadership,” said Dana Anderson, Chief Science Officer at Infleqtion. “By deploying this technology in orbit, we are demonstrating the ...

Space's microgravity appears to shift the location of the brains of astronauts—without a clear effect on their health ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding universe and our place in it ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...
