A great summary of not just extreme space weather. But extreme EXTREME space weather.

Carrington? Puny storm.

Whoa: The European Space Agency's Solar Orbiter spacecraft got a spectacular view of Comet ATLAS (C/2024 G3) as it passed close to the Sun. Look at that enormous, splintered tail!

This comet won't be seen again for another 600,000 years. 🧪🔭

The late-Quaternary megafauna extinctions: Patterns, causes, ecological consequences and implications for ecosystem management in the Anthropocene | Cambridge Prisms: Extinction | Cambridge Core The late-Quaternary megafauna extinctions: Patterns, causes, ecological consequences and implications for ecosystem management in the Anthropocene - Volume 2

The evidence for Homo sapiens playing the dominant role in the global #megafauna #extinctions constitutes one of the clearest, well-supported patterns in #ecology.

Spectra of white dwarfs reveal the elements of the rocky planets that once surrounded the star. Fascinating.
