💁🏻‍♀️ TIL: 🌋☄️ An analysis of 89 major geological events over 260 million years finds #Earth’s biggest disasters cluster every 27.5 million years.

An #NYU geologist suggests this may link interior processes to orbital cycles or the #solarsystem’s motion through the #MilkyWay. The idea remains controversial but has held up against refined #data.

☿️ Meet Mercury: the Solar System's fastest, toughest overachiever.
Closest to the Sun. Fastest orbit in the neighborhood (47 km/s!). A day that's literally longer than its year. And a surface that swings from 430°C at noon to -180°C at night — with basically no atmosphere to soften the blow.

Drawing on #NASA’s RIDGE framework and decades of zero-gravity astronaut #data, he walks through the physiological hazards bone loss, muscle atrophy, fluid shifts, and space anemia.
