The International Astronomical Union defines a planet as a celestial body that orbits the sun, is massive enough that gravity has forced it into a spherical shape, and has cleared away other objects ...
Researchers estimate that the planet has about a 50% chance of being in its star's Hoble zone.
(CNN) — After decades of searching, astronomers have uncovered some of the strongest evidence yet of exoplanets orbiting Barnard’s Star, the nearest single star system to Earth. The four planets are ...

This is a brilliant question because the notion of an orbit is counterintuitive. We know that massive objects (really, any objects with mass) gravitationally attract other massive objects; Newton's ...
Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...
Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a game-changing instrument called NIRPS (Near-Infrared Planet Searcher) is ...
