The nearest star to Earth is, of course, the sun. The nearest star system to Earth, beyond the sun, is the interesting star system known as Proxima Centauri. A red dwarf star located 4.244 light years ...

Proxima Centauri, our nearest stellar neighbor, hosts a potentially habitable planet, Proxima B. Reaching it is a colossal ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted for publication in The Astronomical Journal ...

A small star just over four light-years from Earth has just made a very big statement. In a groundbreaking new study, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have ...

Scientists have discovered what they believe to be a new planet, the closest one ever detected outside our solar system. It is a small, rocky planet not unlike our own, orbiting the sun's closest ...

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 ...

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 ...

NASA's very productive James Webb Space Telescope (JWST) has found compelling evidence for a new planet in the Alpha Centauri star system, our closest stellar neighbor. This potential gas giant, ...

The existence of an Earth-sized exoplanet around the closest star to our sun, Proxima Centauri, has been confirmed by an international team of astronomers, including researchers from the University of ...
