Researchers at the University of Helsinki research the extraordinarily strong magnetic, or solar storm from the year 1859. The case called Carrington Event was the most powerful solar storm in history. And the main question is what caused that corona mass eruption (CME)? Researchers try to find remnants of those particles from the trees of Finnish Lappland. And maybe they found an answer: what caused that unique, extraordinarily strong magnetic storm? Was it some kind of electromagnetic burst? Or was it some kind of antimatter particle? And why did that event happen only ...
