Study Says the Sun Could Produce a Superflare
A paper by Natalie Krivova of the Max Planck Institute for Solar System Research and her co-authors challenges the assumption that the Sun cannot produce superflares, powerful outbursts observed on some Sun-like stars. Published in Philosophical Transactions A, the study says such an event could eventually affect technological society, though the supplied report gives no estimate of when one might occur.
The Sun frequently produces flares that release large amounts of energy, sometimes toward Earth. Compared with other Sun-like stars, however, it has generally appeared relatively quiet and not capable of producing the superflares observed on some stellar counterparts.
A new paper by Natalie Krivova of the Max Planck Institute for Solar System Research and her co-authors challenges that assumption. The paper, published in Philosophical Transactions A, says the Sun is physically capable of producing such a dramatic outburst.
The report says the possibility could matter for a highly technological society. It also notes that some scientists have argued the Sun’s apparent lack of superflares helped enable the development of complex life on Earth.
