Anne Minard Solar eclipses have been blamed in the past for war, famine, and the deaths of kings. But the upcoming total eclipse on August 1 will mostly be celebrated by excited skywatchers—even if it won't break any records.
The sun will be completely obscured for just under two and a half minutes, "a tad on the short side," according to astrophysicist Fred Espenak, an eclipse expert based at the NASA Goddard Space Flight Center.
A typical eclipse lasts for three minutes, Espenak said, and the longest possible is seven and a half minutes.
When it starts, this year's full eclipse will be visible from a narrow arc spanning the Northern Hemisphere.
Its path will begin in Canada and continue northeast across Greenland and the Arctic, then southeast through central Russia, Mongolia, and China.
The eclipse will start around 8:30 a.m. Greenwich mean time in the eastern part of the arc, leading to totality in just under an hour.
In a much wider swath of the globe—including northeastern North America along with most of Europe and Asia—people will be able to see a partial eclipse.
