The expansiveness of the universe could make interstellar communication difficult, even for the most advanced civilizations.

Space scientists look back on three decades of exoplanet discoveries—from rows of massive ‘super-Earths‘ to worlds with ...

Until now, only Proxima Centauri was known to have two and possibly three planets. One of these is in the habitable zone, the distance from its red dwarf sun where liquid water can exist, though it's ...

There might be a huge planet lurking near one of the closest stars to Earth. NASA's James Webb Space Telescope (JWST) has imaged a possible planet near Alpha Centauri A, a sun-like star that forms ...

NASA’s James Webb Space Telescope has detected strong evidence for a giant planet orbiting Alpha Centauri A, the nearest Sun-like star to Earth. Located just 4 light-years away, this possible ...

A giant planet may be orbiting the nearest Sun-like star to Earth, and the discovery is sparking excitement across the astronomy world. Using the James Webb Space Telescope, researchers have detected ...

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 ...

CINCINNATI (WKRC/NASA/CBS Newspath) - Astronomers using NASA's James Webb Space Telescope have discovered compelling evidence of a giant planet orbiting Alpha Centauri A, the closest Sun-like star to ...

The recent discovery of a potential gas giant circling the nearby star Alpha Centauri A has led to speculation that it may be orbited in turn by a habitable moon that could support life, just like in ...

What new methods can be employed to help astronomers distinguish the light from an exoplanet and its host star so the former's atmosphere can be better explored? This is what a recent study accepted ...
