Sea stars move without a central brain, using coordinated tube feet in a way that’s inspiring new robot designs.

"We studied the last several orbits before the merger, when the entwined magnetic fields undergo rapid and dramatic changes, and modeled potentially observable high-energy signals." ...

Satellites and spacecraft in the vast region between Earth and the moon and just beyond—called cislunar space—are crucial for ...

Using an unprecedented amount of high-resolution satellite data, researchers have found that Earth’s fault lines are far weaker—and continents far less rigid—than long-standing geological models ...

How space dogfighting games evolved from vector lines to virtual cockpits.

This week, NASA enters the final stretch of preparations for Artemis II, the first crewed mission to circle the Moon in more than 50 years.

Those concerned that 3I/ATLAS' arrival to our solar system meant that some sort of alien invasion was imminent can breathe a sigh of relief. It's not.

Astronomers found no radio signals from the comet that would suggest it is an extraterrestrial spacecraft. 3I/ATLAS was confirmed as the third known object to enter our solar system from interstellar ...

Scientists found new evidence (or lack thereof) disproving the conspiracy theory that interstellar comet 3I/ATLAS is alien ...

Scientists confirmed the object originated outside our solar system due to its high speed and trajectory. The comet poses no danger and will pass about 170 million miles from Earth. While not visible ...

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously believed. This breakthrough could make global quantum networks far more ...
