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 ...

The appearance of the interstellar objects (ISOs) 'Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come from? Unfortunately, they ...

Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years from ...

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 ...

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 ...

A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how much could already be here. Reading time 2 minutes Our nearest stellar ...

Astronomers found strong evidence that a gassy Jupiter-size world is orbiting one of three stars in the stellar system closest to our own. By Katrina Miller See more of our coverage in your search ...

This NASA/ESA Hubble Space Telescope has given us this stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right), shining like huge cosmic headlamps in the dark.

One of the first things I did when I moved to a new home just south of Orlando after leaving national security think tank-land in DC was to make as many contacts in the space community as I could. I ...

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 ...
