The question of when a new outbreak should occur is not unwarranted. In 1859 occurred such a powerful outburst of telegraph wires caught fire and spectacular auroras appeared as far south as Hawaii and Cuba.
An equally large outbreak in 2015 would most likely have devastating consequences, given the electronically integrated world we live in today with all the satellites and other sensitive equipment. In 1989 there was a much smaller eruption, but still resulted in electricity supply to the entire province of Quebec in Canada were knocked out.
To find out how often these “super explosion” occurs, researchers at the Harvard Smithsonian Center for Astrophysics studied 84 sollika stars for four years. During these years, the scientists found 29 major outbreak, which – according to the researchers – is good news!
According to calculations, this means that it is between 250 and 480 years between each “super explosion”. The most likely scenario is one such eruption every 350 years, say the researchers who recently presented their findings at an astronomical conference in Honolulu, Hawaii.
