More gravitational wave discovery rumors are flying, but this time they've taken a specific -- and, possibly, really exciting -- new twist.
Gravity measurements taken by the orbiting Rosetta spacecraft show the body of comet 67 P/Churyumov-Gerasimenko is about 75 percent dust and 25 percent ice all the way through.
In the roller-coaster rumor mill that surrounds some of the biggest physics endeavors of our time, it pays to remain skeptical when extraordinary claims of historic discoveries are made on social media.
A pioneering satellite is on its way to an orbital perch 930,000 miles away from Earth to test a new technique for detecting elusive ripples in space and time known as gravitational waves.
A century after Albert Einstein unveiled a new concept to explain gravity, his so-called general relativity theory remains fertile ground for scientific observations and experiments.
Exactly 100 years ago on Nov. 25, 2015, physicist Albert Einstein, then 36, presented a fourth and final lecture to the Prussian Academy of Sciences about his new general theory of relativity.
Scientists have known for some time that Phobos, the larger of Mars’ two small moons, is a victim of gravity, edging closer toward its parent planet.
New lunar gravity maps point out a stark and unexpected difference between the sizes of ancient asteroids that slammed into the moon billions of years ago and the sizes of the rocky bodies that occupy the in the Main Asteroid Belt today.
