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 ...

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” ...

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 ...

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) ...

Even though the ingredients for life have been confirmed to be practically everywhere we look, the only world where we've definitively confirmed its existence is Earth. Exoplanet science has exploded ...

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, ...

Add Yahoo as a preferred source to see more of our stories on Google. An artist's illustration of a hot, Neptune-size alien planet. Warm Neptune-size exoplanets are not nearly as common as ...

Space telescopes are revolutionizing exoplanet discovery, allowing astronomers to detect Earth-like worlds orbiting distant stars. By observing subtle dimming of starlight, measuring gravitational ...

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 ...

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 ...

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 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 ...
