Radial velocity (RV) surveys have detected hundreds of exoplanets through their gravitational interactions with their host stars. Some will be transiting, but most lack sufficient follow-up ...

With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the most massive planets known to orbit a low-mass star. Gaia-4b is also the ...

Astronomers using the GRAVITY instrument at the VLT telescopes in Chile have now obtained the first direct confirmation of an exoplanet discovered by radial velocity. As the planet “Beta Pictoris c” ...

The discovery of exoplanets, particularly "hot Jupiters" orbiting close to their stars, challenged existing models of planetary system formation, revealing that planetary migration within ...

Michael Endl is on a mission: As a research scientist with the University of Texas at Austin, he hopes the sum of his astronomy career will be a chart characterizing exoplanets, like you might find on ...

The 2019 Nobel Prize in Physics was awarded for “contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos”. Half the prize went to cosmologist Jim Peebles, ...

Sub-Neptune planets that dance in time with the rest of their planetary systems are less dense than those that don't, planetary scientists have found. Depending on the techniques used for these ...

A team of astronomers, including a researcher from Ohio State, located a planet orbiting two stars that resembles the planet Tatooine from the movie series “Star Wars.” Using a technique known as the ...

Exoplanet of firsts: Artist’s impression of the exoplanet 51 Pegasi b (left) and its star. This was the first exoplanet to be discovered orbiting a main-sequence star (using radial velocity in 1995) ...

Today, at an international ESO/CAUP exoplanet conference in Porto, Portugal, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO’s 3.6 ...

Astronomers have discovered one of the lightest planets ever found and it's orbiting the star right next door to our own, just over four light-years away from Earth. Confirmation of Proxima d is ...
