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 ...

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 ...
