"L 98-59 c could be the first planet smaller than 2 Earth radii with a definitively detected atmosphere," a team of ...

Astronomers have discovered four planets that are just a fraction of the mass of Earth orbiting Barnard’s Star, which is 6 ...

Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a ...

As astronomers delve deeper into the diversity of worlds orbiting distant stars, a new study suggests comparing populations ...

Scientists have discovered a sub-Neptune exoplanet, GI 410 b, using the radial velocity technique. It orbits a nearby star 39 light years from Earth and has a mass 8.5 times that of our planet. The ...

An observational tango has thus emerged between the two methods. The transit method generates a large number of “candidates”, which are then confirmed by spectrographs around the world, determining ...

TESS hunts for exoplanets by looking for a temporary decrease in a star's brightness, also known as the transit method. When a dip in brightness is observed, that suggests a planet has passed in ...

NASA has discovered a new world, named Gliese 12 b. It is roughly the size of Earth, lies in the habitable zone, and orbits every 12.8 days.

In a paper slated for publication April 14 in Science, Currie reports the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a ...

Many exoplanets have been discovered as they transit, or pass in front of, their host star, creating an observable dip in starlight suggesting the presence of a planet. But the elusive planets ...

high-precision transit surveys like those constructed with NASA's Kepler and TESS missions, it's possible to gather such observations. These missions allow astronomers to study exoplanets that are ...
