EX-exoplanet!
Recorded evidence of a star eating a planet before our human eyes!
Must happen quite a lot, wonder if Sol ate a world or two closer than Mercury?
There have been several posts about the paper positing the possible detection of chemistry that hints at biology on an #exoplanet Below is a good deep dive from a researcher. #astronomy

Astronomers have detected the most promising signs yet of a possible #biosignature outside the solar system, although they remain cautious.
They have detected the chemical fingerprints of dimethyl sulfide and/or dimethyl disulfide, in the #atmosphere of the #exoplanet K2-18b, which orbits its star in the #habitable zone.
On Earth, theyare only produced by #life, primarily microbial life such as marine phytoplankton.

Oha, interessant!
"Mit dem James-Webb-Teleskop hat ein Team um Nikku Madhusudhan von der britischen University of Cambridge mögliche Hinweise auf biologische Aktivität in der Atmosphäre des Exoplaneten K2-18 b gefunden. [...] Auf der Erde entstehen die Moleküle Dimethylsulfid (DMS) und Dimethyldisulfid (DMDS) ausschließlich durch biologische Prozesse [...]. Bisher ist kein nichtbiologischer Prozess bekannt, bei dem sich die Stoffe natürlich bilden." #Exoplanet #Leben https://www.spektrum.de/news/exoplanet-zeigt-schwefelhaltige-biosignaturen/2263047
Ein Forschungsteam aus #Cambridge hat offenbar die Vermutung von letztem Jahr bestätigt, dass Dimethylsulfid und -Disulfid in der Atmosphäre von #K218b vorkommen. Heißt, der Planet riecht nach Meer.
Wir sollte uns doch um neue #Raumfahrtantriebe kümmern. Fremde Welten erkunden, die nie zuvor ein Mensch gesehen hat.

So far today, every news report I've read about #exoplanet K2-18b has got its size and distance wrong, and has described the #biosignature chemicals DMS and DMDS as gases (on Earth, they're both colourless, flammable liquids).
It makes you wonder how accurate all the other stories on the news are...
So to be clear any life forms that has started on a different planet, can't be an animal for me. Because other as for every organism on the earth we are not genetically linked to it.
I can really recommend the following essays about this:

Außerirdisches Leben auf naher Wasserwelt? Astronomen bestätigen potenzielle Biosignatur auf dem habitablen Exoplaneten K2-18b. #Exoplanet #Außerirdisch #Biosignatur #JWST #Astronomie #LebenimAll #k218b

Das riecht nach außerirdischem Leben auf K2-18 b! 
Auf dem 124 Lichtjahre entfernten Exoplaneten wurden deutliche Spuren von Dimethylsulfid (DMS) und Dimethyldisulfid (DMDS) gefunden – beides Stoffe, die auf der Erde nur von Organismen produziert werden und für den typischen Geruch des Meeres sorgen.
