Hycean worlds, which are a possible kind of exoplanet with deep oceans surrounded by a thick envelope of hydrogen, could ...

Scientists have just discovered four small, rocky exoplanets orbiting Barnard’s Star, the nearest single star to our solar system after the Alpha Centauri system, NASA announced. Located only six ...

A selection of exoplanets that orbit in the habitable zone around their stars — where water can sit in liquid form on the surface. From left: Kepler-22b, Kepler-69c, Kepler-452b, Kepler-62f ...

The frequency of that stellar wobble reveals an exoplanet’s orbital period and distance from its star, and its strength provides an estimate of the unseen world’s mass. The observations ...

These days, researchers commonly discover exoplanets, or planets outside our solar system. But sometimes there’s a special discovery, like an exoplanet right in our backyard — and that’s the ...

Using data from NASA's Transiting Exoplanet Survey Satellite (TESS) and the HARPS-N high-resolution spectrograph, the researchers were able to identify TOI-1453 b and TOI-1453 c, the two ...
