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 ...

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 ...

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 ...

New simulations reveal that around 1 million "macroscopic" objects from our closest stellar neighbors, the Alpha Centauri system, may already reside in the Oort Cloud, far from sight. When you ...

In a historic discovery that has left scientists and astronomy enthusiasts in awe, the James Webb Space Telescope (JWST) has potentially identified a new exoplanet orbiting Alpha Centauri A. This ...

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 ...

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 ...

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable orbit around Alpha Centauri A, the nearest sunlike star to our solar system ...
