In the paper from 2024, the team looked at long-period objects that crossed the path of Neptune's orbit, finding that their ...

Of the roughly 7,300 active satellites in Earth orbit, about 3,600 are part of SpaceX’s growing fleet of Starlink internet ...

For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research that is transforming life on Earth and shaping the future of exploration.

Earth's orbiting satellites are commonly regarded as if they were suspended in mid-air. It is a fact that they actually experience a state of continuous free fall. This implies that they fall toward ...

The pitch is seductive in its simplicity: AI needs more power than terrestrial grids can supply, so move the data centres into orbit, where the sun never sets and the electricity is free. SpaceX, Blue ...

A spacecraft slowed the orbit of a pair of asteroids around the sun by more than 10 micrometers per second — the first time human activity has altered the orbit of a celestial object, researchers ...

I first encountered the three-body problem 60 years ago, in a short story called “Placet is a Crazy Place” by American science fiction writer Frederic Brown. In Brown’s story, Placet is a planet in a ...
