Lava planets don’t play by the rules of our solar system. These scorching-hot worlds, some no bigger than Earth, orbit so ...

Mars has a cold, desert-like climate with a thin atmosphere that supports extreme temperature variations, from highs of 68 °F ...

Scientists are turning to simulations and experiments to understand how life-indicating molecules behave, so we might know ...

"It confirms K2-18 b to be our best chance to study a potential habitable environment beyond the solar system at the present time." ...

A new paper led by a York University professor and published today in Nature Astronomy introduces a simple theoretical ...

Astronomers have characterized the atmosphere of a young (20 Myr old) transiting exoplanet and found it to be unusually clear and puffy. By analyzing the planet's atmospheric features, they were able ...

Modelling suggests that data collected by JWST will be able to distinguish between planets that are molten to the core and ...

Researchers studied the L 98-59 system and confirmed five rocky planets. One is in the habitable zone and may support liquid water.

Exciting new findings reveal that WASP-121b, a blazing-hot giant planet, may have formed far from its star in a colder, ice-rich region—before migrating inward to its current extreme orbit. Chemical f ...

Planets can be extremely hot when they are born, and new computational experiments show that such planets would have an atmosphere composed of a homogenous mixture of hydrogen and water. As the ...

The planet is about 2.8 times the size of Earth and has a puffy atmosphere, made up of mostly hydrogen and helium. Observations with the W. M. Keck Observatory in Hawaii revealed that helium is ...
