The detection of a large interstellar object in 2017 named 'Oumuamua was a landmark discovery. Figuring out where the wayward ...

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 ...

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 ...

Alpha Centauri, one of the two "Pointer Stars" that help stargazers find the Southern Cross in the Southern Hemisphere, may have a planet in orbit around it. If it does, the Webb Telescope will find ...

A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how much could already be here. Reading time 2 minutes Our nearest stellar ...

Using the James Webb Space Telescope (JWST), astronomers detected a potential gas giant exoplanet, designated S1, orbiting Alpha Centauri A, a star in the closest stellar system to Earth. The ...

Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years from ...

A giant planet may be orbiting the nearest Sun-like star to Earth, and the discovery is sparking excitement across the astronomy world. Using the James Webb Space Telescope, researchers have detected ...

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 ...
