Astronomical & Paleoclimatic Record
Deep Solar Activity & Cosmogenic Spikes
Beyond the familiar 11-year sunspot heartbeat lie multi-century oscillations like the Gleissberg, Suess, and Hallstatt cycles. In ancient tree rings and polar ice cores, our planet preserves signatures of extreme Solar Particle Events (Miyake Events) tens to hundreds of times more energetic than the 1859 Carrington storm.

What is a True "Micronova"?
Identified by ESO's VLT and NASA's TESS in 2022, micronovae are localized surface thermonuclear detonations on accreting white dwarfs in binary systems (~10³⁹ ergs). Our isolated G-type Sun cannot produce a thermonuclear micronova, but it produces violent magnetic superflares and extreme proton storms.
