RE: https://mastodon.social/@proseandpassion/116935425709917770
Where in #space can #planets with #atmospheres be found? C. Cherubim et al. (2026) used #nearinfraredspectroscopy to characterize a #rocky #exoplanet orbiting its host star within the #habitablezone. Planet #LHS1140b exhibits #helium #absorption in its atmosphere, a feature the authors attribute to a helium-dominated #upperatmosphericlayer.

💁🏻♀️ TIL: 🪐🔭 For the first time, astronomers have detected an #atmosphere on a rocky #planet in the habitable zone of another #star.
The super-Earth LHS 1140 b, located 50 light years away, shows signs of a #helium dominated atmosphere escaping into #space. Researchers used the WINERED #spectrograph at Las Campanas Observatory to make the ground-based #discovery.

NASA's James Webb Space Telescope has discovered a hidden giant exoplanet in the Beta Pictoris system using its atmospheric fingerprint instead of traditional imaging. The breakthrough could revolutionize the search for planets beyond our solar system. https://english.mathrubhumi.com/technology/science/nasa-james-webb-discovers-beta-pictoris-d-hidden-giant-exoplanet-looxlpl8?utm_source=dlvr.it&utm_medium=mastodon #NASA #JamesWebb #WebbTelescope #Exoplanet #BetaPictoris
