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.

An exoplanet is a planet from a different star system. Most known exoplanets orbit stars within the Milky Way, but with the help of powerful space telescopes, scientists have discovered exoplanets ...

The enormous structure, which is made up of gas leaking from the exoplanet's atmosphere, is being blown by stellar winds like a giant "windsock," experts say. The exoplanet, WASP-69 b, is a gas giant.

"The rate at which the planet is evaporating is utterly cataclysmic, and we are incredibly lucky to be witnessing the final hours of this dying planet." Using NASA's exoplanet-hunter TESS ...

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 ...

This Collection highlights the results from the Early Science Release programme of the JWST telescope focused on transiting hot giant exoplanets. With its extended wavelength range and its ...

The AstroAI initiative, launched in 2023, uses AI to search for life on exoplanets, such as the exoplanet WASP-39 b imagined in this illustration. IMAGE NASA, ESA, CSA, Joseph Olmsted (STScI) Could ...

Exoplanet LTT9779 b, which orbits a star about 262 light-years from Earth, is so reflective it acts almost like a mirror, the European Space Agency (ESA) said in a press release. This planet's hot ...
