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 ...

The existence of a potentially habitable planet orbiting our closest neighbor, the red dwarf Proxima Centauri, is both an extremely exciting event and sort of "more of the same." While Proxima b is ...

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 ...

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 ...

At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using ...

Astronomers have identified Proxima Centauri b, a rocky planet just over four light-years away, as the closest potentially ...

The detection of a large interstellar object in 2017 named ‘Oumuamua was a landmark discovery. Figuring out where the wayward traveler came from, though, is another challenge entirely, especially ...

The Alpha Centauri star system is just 4.2465 light-years away – a relative hop, skip, and a jump in a galaxy 100,000 light-years across. Wouldn't it be great to visit? Not just with a fleet of ...

This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like. Observations of the triple star system Alpha Centauri using NASA’s James Webb Space Telescope indicate the ...

Engineers have unveiled a bold new concept for an interstellar spacecraft capable of transporting up to 2,400 people on a one-way, 400-year voyage to Alpha Centauri, the closest star system to Earth.

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 ...
