“We derive rotation periods, photometric activity indices, flaring energies, mass loss rates, gyrochronological ages, X-ray luminosities and consider implications for the planetary magnetospheres and habitability.”

“One of the earliest (and biggest) space weather events on record occurred in September 1859, when a massive solar eruption crashed into the Earth's magnetosphere, triggering a geomagnetic storm that lasted for days.”

“Earth is surrounded by a magnetosphere — an invisible bubble of magnetism generated by the powerful churning of molten metals at Earth’s core. It prevents our atmosphere from being stripped away by solar winds blasting it from the sun. While the magnetosphere has been a constant presence for billions of years, its strength waxes and wanes over time.”
