Mikko TuomiAn international team of astronomers has discovered a new extrasolar <a href="https://scicomm.xyz/tags/planet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#planet</a> orbiting a nearby <a href="https://scicomm.xyz/tags/star" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#star</a> known as GI 410.The newfound alien world was classified as a sub-Neptune <a href="https://scicomm.xyz/tags/exoplanet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#exoplanet</a> with a mass of at least 8.4 Earth masses.The planet GI 410 b orbits its star every 6.02 days, at a distance of some 0.053 AU.The astronomers underlined that the planet may have an active interaction with the stellar high-energy radiation and wind particle fluxes.<a href="https://scicomm.xyz/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://phys.org/news/2025-04-neptune-exoplanet-orbiting-nearby-star.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://phys.org/news/2025-04-neptune-exoplanet-orbiting-nearby-star.html</a>

TöpferDie Erhitzung der Erde bleibt trotz etlicher anderer Sorgen das größte globale Problem. Mein Eindruck ist, wir - die Menschen - argumentieren wie Süchtige, die um das Problem der Sucht wissen und allen erklären, bald aufzuhören. Statt es sofort zu tun, wartet man ab und erhöht die Dosis. Schließlich hat man versprochen: Bald wird alles gut. <a href="https://hessen.social/tags/klima" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#klima</a> <a href="https://hessen.social/tags/Klimawandel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Klimawandel</a> <a href="https://hessen.social/tags/wetter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#wetter</a> <a href="https://hessen.social/tags/EU" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EU</a> <a href="https://hessen.social/tags/koalition" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#koalition</a> <a href="https://hessen.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://hessen.social/tags/astronomie" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomie</a> <a href="https://hessen.social/tags/erde" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#erde</a> <a href="https://www.faz.net/aktuell/politik/inland/kommentar-zu-copernicus-bericht-das-klima-verlangt-klimapolitik-110420940.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.faz.net/aktuell/politik/inland/kommentar-zu-copernicus-bericht-das-klima-verlangt-klimapolitik-110420940.html</a>

AstroPuNkPOV: You’re Stargazing with Me at a WinerySpent the weekend doing what I do best—chasing dark skies, pointing telescopes at space, and accidentally becoming a wine guy 🍷✨ Headed out to my favourite dark sky site, helped out with a public viewing night at the stunning Hanging Rock Winery (yes, wine and stargazing is a thing now), and soaked in some seriously unreal views of the night sky.
