In 2012, astronomers excitedly announced the discovery of Alpha Centauri Bb, the first exoplanet around our nearest neighboring star system. Here's how it all fell apart.

The closest star system is Alpha Centauri, three stars only about 4.1 light years away. Brown dwarfs are large, roughly 13 to 80 times heavier than Jupiter, ...

My science fiction novel “Proxima,” published in 2013, is about a habitable planet of the star Proxima Centauri, a “red dwarf,” small and dim, that is the nearest star of all to our sun.I ...

If you want to study the stars, there’s no better place to start than close to home. After all, the nearest star is just 93 million miles (150 million kilometers) away: the Sun.

We live in a world defined by inches, feet and miles (or centimeters, meters and kilometers, if you prefer), and it’s not difficult for most of us to ...

The closest star to us has an Earth-sized planet. Another nearby red dwarf star, TRAPPIST-1, has seven. The Kepler space telescope finds new exoplanets seemingly every day.

The closest star, Proxima Centauri, also hosts an exoplanet that scientists believe could have the conditions necessary for ...

The star is named after the American astronomer Edward Emerson Barnard, who measured its motion relative to the Sun back in 1916. Artist’s impression of Barnard b orbiting Barnard’s star.

Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our sun. On this newly ...
