An artist's impression of a flare from Proxima Centauri, modeled after the loops of glowing hot gas seen in the largest solar flares. Exoplanet Proxima b is shown in the foreground. Proxima b orbits ...

The third-brightest star in the sky, Alpha (α) Centauri, gleams in the southern constellation Centaurus. Since it is positioned at a declination of almost –61°, only stargazers located south of ...

Laser sail propulsion is an idea that won't go away. By aiming powerful Earth-based lasers at tiny spacecraft with light sails, tiny spacecraft can be accelerated to near-relativistic speeds without ...

Astronomers have found evidence of a third planet around the closest star to the sun, reinforcing the idea that planets are common around the stars of the galaxy, even some of its smallest. And while ...

Quick. What's the closest star after the sun? If you said Alpha Centauri you're one-third correct. Alpha is actually a triple system comprised of Rigil Kentaurus (Alpha Centauri A), Toliman (Alpha B) ...

The closest star to Earth, Proxima Centauri (PC), is still about 8000 times further away from us than Pluto. Propelling a probe to PC will require a much higher cruising speed than we can currently ...

Astronomers have found an Earth-like planet orbiting our nearest neighbour, the red dwarf star Proxima Centauri. So any chance that planet may be habitable? AFTER YEARS OF searching, an international ...

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, ...
