The interstellar comet 3I/Atlas reached its closest point to the sun. Here's how to follow the rest of its journey away from our solar system.

Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

An observatory detected the first radio signal from the interstellar object 3I/Atlas. Here’s what it means.

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number theory to explain quantum fractals.

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

What sneaky invisible forces enable these instruments to locate buried treasure?

Which film camera should you get? Which films are the best? We demystify the world of analog photography to help you get started.

This $400 set comes with minifigures of the complete Next Gen crew, including Picard, Riker, and Wesley Crusher’s portable tractor beam.

Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development.

Project Amplify is Nike’s latest attempt to put some spring in your step with help from a powered mechanism that enhances the natural movement of the human ankle and lower leg.

By shifting water to a higher elevation, the giant Three Gorges Dam caused the Earth to spin more slowly.
