In a groundbreaking new study, researchers have unveiled the existence of a “cosmic highway”—a pathway of interstellar material from the Alpha Centauri system that may already be linking our solar ...

The search for interstellar visitors has taken an unexpected turn. While previous discoveries like ‘Oumuamua and Comet 2I/Borisov proved that objects from beyond our solar system can pass through, new ...

One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks ...

Interstellar asteroids visiting our solar system from parts unknown used to be the stuff of science fiction. But today, we know of at least two such bodies Oumuamua and 2I/Borisov respectively ...

NASA’s James Webb Space Telescope has detected strong evidence for a giant planet orbiting Alpha Centauri A, the nearest Sun-like star to Earth. Located just 4 light-years away, this possible ...

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable orbit around Alpha Centauri A, the nearest sunlike star to our solar system ...
