The planet endures so much stellar energy that astronomers have long assumed its atmosphere evaporated eons ago. However, new ...

When scientists study exoplanets, planets orbiting stars other than the Sun, they often lack three-dimensional information.

Imagine living on a planet where a full year lasts only 11 hours. This is the case with TOI-561 b, a rocky planet about 280 ...

Astronomers have applied a new mapping technique to the atmosphere of a peculiar exoplanet. WASP-17b is a hot Jupiter, a gas giant orbiting extremely close to its star. So close, in fact, that the ...

Exoplanets continue to challenge what we have come to expect. Take TOI-561 b, a super-Earth about twice as massive as our planet, orbiting so close that one side is stuck always in starshine. It was ...

A scorching lava planet 280 light-years away has surprised astronomers by apparently maintaining a thick atmosphere despite ...

Researchers are investigating possible gemstone-forming materials in the atmosphere of an unusually hot and puffy exoplanet.

Webb observations suggest TOI-561 b has a reflective atmosphere, with mineral clouds offering a possible explanation for this lava planet’s cooler dayside.

Astronomers using the James Webb Space Telescope have discovered that a distant alien planet's atmosphere is surprisingly lopsided. Located 1,300 light-years away, the scorching gas giant WASP-17b ...

A rocky planet exposed to extreme heat from its star appears to reflect nearly three-quarters of the starlight that reaches ...

A rocky lava planet once thought to be too extreme to have an atmosphere appears to be wrapped in one with a reflective layer ...

Earth may have produced much of its water during the planet's formation, as rocky pebbles reacted with the hydrogen-rich ...
