Again an astronomical topic:
Two snapshots of Proxima Centauri b, the nearest "Earth-like" exoplanet. Proxima Centauri together with the double star Alpha Centauri physically forms a triple system.
https://en.wikipedia.org/wiki/Proxima_Centaurihttps://en.wikipedia.org/wiki/Proxima_Centauri_bHowever, Proxima b is probably not a "second Earth". Its parent star, a red dwarf, undergoes unpredictable, strong energetic bursts of radiation, called ,,flares" ( protuberances, coronal mass ejections). These flares can be stronger in the UV and X-ray range than corresponding outbursts on the surface of the Sun. Also the other brightness of the star can increase dramatically during such an outburst. All this can strongly affect the habitability of the nearby planet "Prox b".
The two renders show on one side a "quiet" Proxima, on the other side the same area at an "active" Proxima. An (assumed) life form there helps itself by emitting the excess energy in the form of visible light during active phases of the star, similar to the bioluminescence of terrestrial organisms.
Through the atmosphere, thinned out by many eruptions in the meantime, the brightest stars are visible, especially of course the two bright stars of Alpha Centauri.
