Observations of Exoplanet WASP-69b has uncovered a 350,000-mile-long comet-like tail. The tail is a result of its escaping ...

A study using the Very Large Array radio telescope may have discovered a magnetic field on exoplanet YZ Ceti b. Magnetic ...

Exoplanets are planets that orbit stars other than the sun and thus exist outside the solar system. The word "exoplanet" ...

This animation shows magnetic activity in an exoplanet. The planet is a gas giant like Jupiter, but it’s very close to its host star and tidally locked: one side always faces the star and is scorching ...

Astronomers have been looking for exoplanets orbiting Barnard's Star – the nearest solitary star to our Solar System, at just 5.96 light-years away – since its discovery in 1916. Unconvincing signs of ...

When a distant exoplanet transits, or crosses in front of its star, it causes a slight dip in the star’s brightness. The Kepler space telescope measures this dip in a star’s brightness over time.

Researchers have developed a new coronagraph—an optical device that blocks out light from a bright source—that could make it possible to see distant exoplanets obscured by light from their parent ...

Scientists might have just found Earth's icy, distant cousin a few hundred light-years away. HD 137010 b is one of thousands of exoplanets, or planets that orbit other stars, and is potentially the ...

The farthest planet from the Sun, Neptune, is the windiest place in the solar system, with winds that whip through at speeds reaching more than 0.3 miles per second (0.5 kilometers per second). That’s ...
