Scientists have developed a new technique that could help them understand "polka dot" stars using the transits of exoplanets.

As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.

Astronomers using NASA's James Webb Space Telescope have found strong evidence for a new exoplanet — one orbiting Alpha Centauri A, the nearest sun-like star to Earth.
