Extremely Large Telescope could sense hints of life at Proxima Centauri in just 10 hours, simulations suggest
The Extremely Large Telescope (ELT), currently under construction in northern Chile, will give us a better view of the Milky Way than any ground-based telescope before it. It's difficult to overstate ...
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 ...
One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks ...

Which nearby stars around the sun are most likely to host life?
Within a few dozen light years of the Sun, the sky is crowded with stars that could, in principle, host living worlds. I want ...
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, ...
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 ...
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 ...
