Galaxies like the Milky Way boast more than spirals; they also have feathers, where clumps of new stars are born. Astronomers ...

Scientists propose a relatively simple yet still complicated tabletop experiment to test the quantumness of gravity, aiming to reconcile general relativity and quantum mechanics.

So, although gravity feels weak here on Earth… it certainly isn't weak everywhere across the universe. And that's because gravity is an additive force. It scales with mass. So, the more massive ...

Sunita Williams' stay beyond her initial mission timeline was primarily due to concerns about the Boeing CST-100 Starliner.

Neutrinos may be the key to quantum gravity, potentially leading to a unified theory combining quantum mechanics and general relativity.

NASA astronauts Butch Wilmore and Sunita Williams face potential long-term health issues after a nine-month space mission.

NASA astronaut Sunita Williams and her colleague Barry "Butch" Wilmore are finally set to return to Earth after an extended ...

Sunita Williams returns from 9 months in space, facing severe muscle loss, weakened bones, and cancer risks. NASA's intense rehab program will help her and Wilmore rebuild strength.
