‘Cannibal’ sun eruption gives departing astronauts their best aurora

Astronauts bidding farewell to the International Space Station enjoyed the most spectacular aurora display of their entire mission over the weekend after a massive blast of material from the sun reached our planet. 

The sun has been acting out lately, waking up to its new period of activity after years of quietness. This variation is part of the sun’s regular 11-year cycle, the little understood ebb and flow of sunspots and solar flares that is next expected to peak in 2025.
