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 ...

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 – ...

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 ...

Sometimes it takes a while for the meaning of a new scientific discovery to really sink in. In the case of the planet Proxima Centauri b, announced last week, it may take decades or even centuries to ...

Astronomers have discovered a planet 10 times the size of Jupiter -- Earth's largest neighbor -- in a solar system hundreds of light years away. But what got their attention was the fact that, based ...

The Alpha Centauri AB system is an attractive one for radial velocity observations to detect potential exoplanets. The high metallicity of both Alpha Centauri A and B suggest that they could have ...

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.

This image shows the most massive planet-hosting star pair to date, b Centauri, and its giant planet b Centauri b. (Photo by ESO/Janson et al.) (CN) — Scientists with the European Southern Observatory ...
