JWST discovers reflective planet with potential water vapor.

A planet outside our solar system, GJ 1214b, has an "unusually shiny atmosphere" and may contain significant amounts of water vapor, according to a study published in the journal Nature. The planet is covered in a deep haze that has made it difficult to study, but the James Webb Space Telescope recently helped reveal new information about it. Researchers tracked the planet through nearly its entire orbit and found that its atmosphere reflects a large proportion of the light from its parent star instead of absorbing it and becoming hotter. The research also suggests that GJ 1214b may have formed farther away from its star, then moved inward toward its current orbit.
