Reanalysis Of The Eclipses Of LHS 1140 c: No Evidence Of An Atmosphere And Implications For The Internal Structure Of The Planet
We present the reanalysis of three 15 micron JWST/MIRI secondary eclipses of LHS 1140 c, a warm super-Earth (Rp = 1.272 R⊕) in a 3.78-day orbit around an M4.5 dwarf.

Statistical Geochemical Constraints On present-day Water Outgassing As A Source Of Secondary Atmospheres On The TRAPPIST-1 Exoplanets
The TRAPPIST-1 planetary system is observationally favorable for studying if planets orbiting M stars can retain atmospheres and host habitable conditions. Recent JWST secondary eclipse observations of TRAPPIST-1 c rule […]

Echoes of “Avatar”: Spruce Trees Communicate During A Solar Eclipse
Editor’s note: In the “Avatar” film series the interconnectedness of trees and other life forms is at the core of Pandoran ecosystems. On Earth, large expanses of trees exists wich […]

Terraforming / Geoengineering: Clouds Dissipate Quickly During Solar Eclipses As The Land Surface Cools
Clouds affected by solar eclipses could influence the reflection of sunlight back into space and might change local precipitation patterns.
