Is Our Sun In A 9,000 Year ‘Feeble Phase?’ Similar Stars Are Five Times More Fickle, Find ScientistsThis is at the cutting edge of astronomy. “The origin of the solar cycle in not fully understood, and is thus one of the biggest unsolved problems in solar physics,” said Reinhold. “Apart form the 11-yr cycle, there exist other periodicities in solar activity, such as the 70-100 years Gleissberg cycle (and) there are speculations about longer cycles with periods up to several thousands of years.” Such long cycles are very difficult to measure.It’s therefore possible that the Sun has been unusually feeble over the past 9,000 years—and its solar dynamo could still be slowing—or that it’s capable of massive fluctuations we’ve just not yet witnessed. “One possible conclusion of this result is that the Sun did not reveal its full range of activity over the last 9000 years, and could potentially become as active as the other stars that we studied,” said Reinhold. That would mean more intensive solar winds, which could cause power outages, knock-out satellites, and cause dangerously higher radiation levels for astronauts in space or on the Moon.
