The Sun isn’t the only star to produce stellar flares. On April 21, 2021, a team of astronomers published new research describing the brightest flare ever measured from Proxima Centauri in ultraviolet ...

BERKELEY, Calif. — The nearest exoplanet to Earth may have a neighbor. Astronomers have detected a candidate planet circling the star Proxima Centauri, a dim red dwarf that lies just 4.2 light-years ...

A pale red dot not far from our sun may be orbited by a pale blue dot much different than Earth. In a shocking find, astronomers Wednesday announced their discovery of an Earth-sized planet orbiting ...

The European Extremely Large Telescope is one of the yet-to-be-built observatories that could target the nearest exoplanet, Proxima Centauri b, for direct imaging.. (Credit: ESO) GUADALAJARA, Mexico – ...

Efforts to send some type of man-made probe to the Alpha Centauri system may have gotten a huge boost Tuesday as the European Southern Observatory (ESO) confirmed the existence of a planet around ...

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 detected a massive stellar flare -- an energetic explosion of radiation -- from the closest star to our own Sun, Proxima Centauri, which occurred last March. This finding raises ...
