The comet will come much closer to Jupiter in March, zipping within 33 million miles (53 million kilometers). It will be the mid-2030s before it reaches interstellar space, never to return, said Paul ...

Relativity Space tried to build spacecraft with 3D printing. After a series of setbacks, Google’s former chief has taken the ...

On average, Martian time ticks roughly 477 millionths of a second faster than terrestrial clocks per Earth day. But the Red ...

An artist’s impression depicts the accretion disk surrounding a black hole, in which the inner region of the disk wobbles. In this context, the wobble refers to the orbit of material surrounding the ...

Scientists find that time on Mars runs 477 microseconds faster than on Earth, a discovery that could enhance deep-space communication and future exploration ...

Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...

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 ...

A startup established three years ago to churn out a new class of high-power satellites has raised $250 million to ramp up ...

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

Trident Technical College astronomy professor Blake Crosby has a gift for translating complex science into fascinating conversation. He kindly agreed to answer imaginative questions about cosmic myste ...

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 ...
