Gaia-4b, a giant exoplanet orbiting a small star, is the first planet confirmed using Gaia’s astrometric technique.

Planet demographics reveal a puzzling lack of worlds in a certain size range throughout the galaxy F or centuries our solar system was the only planetary system known to humans. We had no proof other ...

With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the ...

rhymes with fluid) is a high-precision radial-velocity spectrograph that is designed to measure the extremely minute wobble of nearby stars using ...

Using in part the NEID spectrograph mounted on the WIYN 3.5-meter Telescope at the U.S. National Science Foundation Kitt Peak National Observatory, a Program of NSF NOIRLab, a team of astronomers have ...

It uses a planet-detecting method called radial velocity, also known as the wobble or Doppler method, which can detect 'wobbles' in a star caused by the gravitational pull of an orbiting planet. Using ...

Scientists using data from the European Space Agency’s Gaia mission have made a groundbreaking discovery: a massive exoplanet ...

A number of techniques have been used to find them, such as the transit method, which detects the dimming of a star's light due to the presence of the passage of a planet, or the radial velocity ...

By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new giant "planet," plus a new brown dwarf.

Data from the Gaia spacecraft shows that even unassuming stars can host monumental companions like massive planets.
