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 ...

Astronomers have found nearly 6,000 exoplanets orbiting other stars. But for every confirmed detection, there are countless mere hints, inconclusive observations that could just as well be blips of ...

The appearance of the interstellar objects (ISOs) 'Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come from? Unfortunately, they ...

Astronomers have used NASA's James Webb Space Telescope to find strong evidence for a planet orbiting a star in the triple system closest to our own sun. At just 4 light-years away from Earth, the ...

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 ...

Alpha Centauri A, on the other hand, is much more interesting from an Earth perspective. It's a G2V star similar to the Sun, which is a kind that we know can support a life-bearing planet because ...

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 ...
