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 ...

Astronomers have found strong evidence of a giant gas planet orbiting a star in a solar system close to our own sun. Four light-years away from Earth, the Alpha Centauri triple-star system has long ...

The Alpha Centauri star system, located just four light-years from Earth, might host a giant planet in its habitable zone. The observation of a Saturn-sized planet by the James Webb Telescope in ...

Scientists may have found the first planet ever detected around our closest “solar twin,” a star called Alpha Centauri A, the same real-life star that was home to the fictional moon Pandora in James ...

If Earth needs to borrow a cup of sugar, it's comforting to know that there may be a convenient, possibly habitable, world orbiting Alpha Centauri only 4.34 light years away – at least, if the ...

Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a game-changing instrument called NIRPS (Near-Infrared Planet Searcher) is ...

How close to Earth could we find the next Earth-like exoplanet? This is what two papers accepted in The Astrophysical Journal Letters hopes to address as a team of more than two dozen researchers ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

New research suggests that technological civilizations in the Milky Way are extremely rare, with the closest potentially ...

Discovered: Once Earth's ruined we should hightail it for the Tau Ceti system; how reindeers get red noses; one in two men will get cancer; what flying squirrels have in common with Top Gun. A ...
