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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Artist's concept of a stellar flare from Proxima Centauri. Credit: NSF/AUI/NSF NRAO/S. Dagnello At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is ...

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 ...

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 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, ...
