The mysterious interstellar object 3I/Atlas will pass by Earth on October 29, and scientists explain what it means and whether it’s safe.

An object spotted with help of citizen scientists was moving so fast through the Milky Way that it could escape the gravity of the galaxy and reach intergalactic space, new research has found. Likely ...

Indian scientists are analysing fresh data on 3I/Atlas after early readings suggested the interstellar visitor was detected before NASA’s report.

Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...

When a baseball player hits a home run off a 100-mph fastball, how can the slugger's brain track such a fast-moving object? Scientists may now have the answer. In a new study, they discovered how the ...
