Nachweis erbracht, dass starke Magnetfelder aktiver Sterne koronale Massenauswürfe vollständig unterdrücken können. .. erklärt, warum massereiche stellare Eruptionen bei Sternen viel seltener beobachtet werden als bei der Sonne. .."https://www.aip.de/de/news/stellar-eruptions-laboratory-experiment/

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.

🌍☀️ Scientists at #ArizonaState and #Caltech used the #JWST to produce the first weather report for WASP-94A b, a gas giant 700 light-years from #Earth.
The #planet has two different #weather sides: a morning edge with #clouds made of vaporized #rock and an almost cloud-free evening edge, driven by temperature differences and powerful winds.

I was feeling some of the lowest lows of my life last night/today. Then I saw a news article about an exoplanet that’s shaped like a lemon. The universe is so unserious sometimes. Maybe there’s things worth sticking around for after all.

Die Autorin erzählt unterhaltsam, wie sie mit der Suche nach fremdem Leben eine erfolgreiche Astrophysikerin wurde. Ihr Buch hätte aber von mehr Sorgfalt profitiert. Eine Rezension
Die Astrophysikerin Lisa Kaltenegger beschreibt ihren Werdegang und berichtet von ihrer Forschung. Ein unterhaltsames Buch – mit Ungenauigkeiten.

CW: LHS 1140 b may be our 'best bet' at finding a habitable exoplanet with ocean(s) and atmosphere
LHS 1140 b “lives in its star's habitable zone, otherwise known as its ‘Goldilocks zone.’"
“This is the first time we have ever seen a hint of an atmosphere on a habitable zone rocky or ice-rich exoplanet," said Ryan MacDonald, a NASA Sagan Fellow
“the team might have even found evidence of ‘air’ on it.

Chemical Soups Around Cool Stars
This artist's conception shows a young, hypothetical planet around a cool star. A soupy mix of potentially life-forming chemicals can be seen pooling around the base of the jagged rocks.

In case you do not remember how the #night #sky was before all the #StarLink / #SpaceX #satellites, here is one of the #timelapse I did 5 years ago from the #ESO #LaSilla #observatory, in #Chile
The #video lasts 1 minute but it corresponds to 10 hours.
The big dish is a decommissioned radio #telescope. In the background there is the 3.6-m telescope with its #exoplanet-hunting instrument #HARPS

On December 27, 2006, the European space observatory CoRoT was launched. CoRoT‘s two objectives are to search for extrasolar planets with short orbital periods, particularly those of large terrestrial size, and to perform asteroseismology by measuring solar-like oscillations in stars.
