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 ...

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

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” ...

As the first successful technique used to detect exoplanets orbiting distant stars, the radial velocity method aims to detect a periodic Doppler shift in a stellar spectrum due to the star's motion ...

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 ...

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 ...

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 ...

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 ...

New research has identified two distinct populations of sub-Neptunes that have densities linked to resonance. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...
