To help, you’ll have to master the same techniques scientists use to find and characterize exoplanets – worlds orbiting faraway stars.

Supersonic winds on this exoplanet, designated WASP-127b, travel at a mind-bending 5.5 miles per second (9 kilometers per second). The speed of sound on Earth is roughly 0.21 miles per second (0. ...

When the first exoplanet was discovered in 1995, Sara Seager and Dave Charbonneau were graduate students at Harvard. Both were studying topics totally unrelated to planets orbiting distant stars.

And that’s exactly what scientists have been doing for decades: searching for exoplanets, worlds orbiting faraway stars. They’ve had tremendous success: So far, NASA’s official count of ...

Astronomers are uncovering new insights into exoplanetary atmospheres, and a recent study on WASP-107 b has turned conventional models on their heads. This distant planet, with its incredibly low ...

Jamie Carter is an award-winning reporter who covers the night sky. Scientists have discovered two “super-Earth” exoplanets, one of which is in its star’s habitable zone. That means liquid ...

A new exoplanet, TOI-6038 A b, has been discovered orbiting a bright late F-type star about 578 light-years away. It is approximately 6.41 times the radius and 78.5 times the mass of Earth, with a ...
