A rocky planet with a 24-hour orbit and an ice giant that takes five years to complete its orbit have been detected orbiting ...

The discovered gaseous planet, named TOI-4465 b, is located around 400 light-years from Earth and is around the same size as ...

Astronomers have made a remarkable discovery in the Kepler-139 star system, uncovering an alien planet that had previously ...

Astronomers discover a new strategy for detecting exoplanets: look for aligned binary stars that reveal hidden worlds more ...

The radial velocity method uses tiny shifts in the light of a star as an orbiting planet gravitationally tugs on it. As a star is pulled away from Earth, ...

For radial velocity, we look for red- or blue-shifts in the light received from the star, caused by a planet tugging the star in different directions as it orbits. Obviously, ...

In the same way that an exoplanet can be detected by looking at the pull on its parent star, the wobble in D9’s orbit — what astronomers call its radial velocity — indicated there were two ...
