Hubble telescope sees an angry star and an evaporating planet

[Admin]

Quite close to our solar system, an angry red dwarf star is terrorizing a misfortunate planet by ripping away the world's atmosphere.

Totally amazing auroras?

Red Dwarf super high energy flares, a thousand times our Sun's blasting away at the planet from just 6 million miles away.
Yes, very bright auroras, thousands of times brighter than ours, tearing away the atmosphere..

Apparently red dwarf stars can obliterate an exoplanet atmosphere like what is documented now for the AU Mic system, so abiogenesis working on an exoplanet with little or no atmosphere should prove interesting for experiments in the labs . There are a number of reports out now for the AU Mic exoplanet system.

Atmospheric escape observed in young Neptune-sized exoplanets can provide insight into and characterize which mechanisms drive this evolution and at what times they dominate. AU Mic b is one such exoplanet, slightly larger than Neptune (4.19 R⊕)..."
