A little over four light-years away is Alpha Centauri, the closest star system to the Sun. And in August 2016, researchers announced they’d found a long-searched-for planet around Proxima Centauri, ...

Proxima b is very promising. It orbits a red dwarf star called Proxima Centauri in a system with three stars in it. Proxima Centauri is small. It only has between 7.5% and 50% of our Sun’s mass.

Astronomers believe they have discovered a new world orbiting Proxima Centauri. Proxima Centauri is the closest star to our Solar System. It's located roughly 4 light-years away. As such, it has long ...

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 ...

Astronomers have confirmed more than five thousand planets orbiting stars beyond our solar system, yet the question that captures public imagination remains simple: how close is the nearest world that ...

The nearest known exoplanet to Earth, a planet orbiting Proxima Centauri, experiences some pretty nasty space weather from its parent star. But previous work on the space weather of Proxima relied on ...

Looking back from a distance, whether that be time or physical separation, can provide us with a fresh perspective on who we are and how far we've come. In our daily lives, Earth appears flat and ...

Planets like Proxima Centauri b experience tides hundreds of times stronger than ones that move Earth’s oceans twice a day. The force of those tides also tugs on the planet’s atmosphere, but a recent ...
