The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by ...

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in ...

Astronomers have attempted to explain the non-gravitational acceleration of comet 3I/ATLAS, our third confirmed interstellar visitor, in a way that removes the need for "non-natural hypotheses for ...

Add Yahoo as a preferred source to see more of our stories on Google. 3I/ATLAS showed signs of non-gravitational acceleration as it passed near the sun, attracting global scientific attention. Harvard ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

The triangle ain't equilateral. Also, I read the jar drawing as being constant speed, not constant acceleration. Each consecutive falling object is at a constant horizontal distance. At the small ...

Everything in the universe has gravity — and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...
