A team of astronomers from the Grenoble Alpes University in France and elsewhere, reports the detection of a new sub-Neptune exoplanet orbiting an M dwarf star. The newly found alien world, designated TOI-269 b, is nearly ...
Using the radial velocity (RV) method, an international team of astronomers has discovered two new exoplanets transiting a nearby M-dwarf star known as GJ 1002. The newfound alien worlds have masses similar to that of our ...
(PhysOrg.com) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the ...

(Phys.org)—An international team of astronomers has discovered three new exoplanets using a Qatar-based planet-searching survey. The newly discovered gas giant exoworlds belong to the so-called "hot Jupiter" family of planets ...
How do you make an Earth-like planet? The "test kitchen" of Earth has given us a detailed recipe, but it wasn't clear whether other planetary systems would follow the same formula. Now, astronomers have found evidence that ...
