No Earth-Like Atmosphere Found on Exoplanet TRAPPIST-1 D
NASA's James Webb Space Telescope found no Earth-like atmosphere on TRAPPIST-1 d, ruling out clear hydrogen-rich and cloud-free atmospheres with over 95% confidence.
- Researchers using NASA’s James Webb Space Telescope found that exoplanet TRAPPIST-1 d, orbiting a red dwarf 40 light-years away, lacks an Earth-like atmosphere.
- This conclusion follows precise spectroscopic measurements ruling out thick hydrogen-rich or cloud-free atmospheres, amid challenges from the star’s frequent high-energy flares.
- Lead author Caroline Piaulet-Ghorayeb explained the planet could have a thin atmosphere like Mars, thick clouds like Venus, or be an airless rock, with further studies planned on outer planets.
- Piaulet-Ghorayeb expressed optimism about the potential for atmospheres to exist on the outer TRAPPIST-1 planets, highlighting that ongoing studies with the Webb telescope are focusing on planets e, f, g, and h, which may still retain significant atmospheric components.
- These results establish a foundation for future missions like NASA's Habitable Worlds Observatory aimed at understanding atmospheric retention and the potential for life on rocky exoplanets.

The JWST Shows Us That TRAPPIST-1d Is Not As Earth-Like As We Hoped
The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our Solar System because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from the NASA/ESA/CSA James Webb Space Telescope, it does not have an Earth-like atmosphere.
TRAPPIST-1d isn't the Earth-like planet scientists had hoped it to be, according to JWST data
As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.
Scientists hoped to find a second Earth, but the latest data from the "James Webb" telescope via Trappist-1d shows something quite different.
