Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

Scientists reveal why time moves faster on Mars than on Earth, and how this affects future space communication and navigation ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually ...

Even worse, the orbit of Mars is elliptical (think of a slight oval rather than a perfect circle), which means that sometimes ...

Black holes are notoriously difficult to spot unless they are active, and one type of activity is the destruction of a star, ...

Scientists detect a 20-day wobble from a star-shredding black hole, confirming spacetime twisting predicted by Einstein.

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

In 1919, British astronomers Arthur Eddington and Frank Dyson organised an expedition to Príncipe, a forested fleck of land ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...

A new warp-drive study proposes a novel segmented design that brings hyper-fast space travel one step closer to becoming a ...

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...
