Space Facts Infographic: All the Planets to Scale

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.

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

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

“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.

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.

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.

The math behind even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major advances toward understanding it.

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

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

Unusually warm ocean temperatures fueled one of the worst hurricanes on record. New research finds climate change increased the storm’s likelihood.
