The planet is one of the best worlds for follow-up studies to determine whether it could be habitable or not.

Using HARPS and HARPS-N spectrographs, astronomers have observed a nearby K-type star designated HD 176986, known to host two ...

Only 11.4 light-years away, two exoplanets have been detected around a neighboring star. One of them, Gl725Bc, is located in ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

A giant planet may be orbiting the nearest Sun-like star to Earth, and the discovery is sparking excitement across the astronomy world. Using the James Webb Space Telescope, researchers have detected ...
