JWST finds signs of a thick atmosphere around a rocky exoplanet After coming up empty in other planetary systems, NASA’s flagship telescope has found the best evidence yet of a rich atmosphere ...

A secondary atmosphere on the rocky Exoplanet 55 Cancri e. Nature, 2024; DOI: 10.1038/s41586-024-07432-x ...

In addition, a secondary atmosphere was found to surround 55 Cancri e by scientists, and it is thought to be caused by volcanic outgassing on the planet's surface. The secondary atmosphere further ...

If this result is confirmed, LHS 1140 b would be the first temperate planet to show evidence of a secondary atmosphere formed after the planet’s initial formation.

This could mean that LHS 1140 b has a secondary atmosphere, something that usually forms after a planet has lost its thicker primary atmosphere. The study also found that 10 to 20 percent of the ...

Current models indicate that if LHS 1140 b has an Earth-like atmosphere, it would be a snowball planet with a vast "bull's-eye" ocean measuring about 4,000 kilometers in diameter, equivalent to ...

And yet, data from Webb suggests 55 Cancri e has the thin but dense atmosphere you'd expect from a rocky planet. Past analysis suggests 55 Cancri e is about twice the size and mass of Earth ...

“Given the limited visibility of LHS 1140b, several years’ worth of observations may be required to detect its potential secondary atmosphere,” the researchers said in the same study.
