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 ...

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 ...

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” ...

An international team of astronomers released the largest-ever compilation of exoplanet-detecting observations made using a technique called the radial velocity method. They demonstrated how these ...

Warm Neptune-size exoplanets are not nearly as common as super-Earths or hot Jupiters — and we are now closer to finding out why. Our galaxy apparently has a dearth of Neptune-size worlds that orbit ...

IMAGE: Artist’s impression of Kepler-16b, the first planet known to definitively orbit two stars — what’s called a circumbinary planet. The planet, which can be seen in the foreground, was discovered ...

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 ...
