In the style of an airline safety announcement, NASA describes how to safely view the 2017 total solar eclipse that will cross the continental United States on Aug. 21:
The NASA "airline attendants" caution against looking directly at the sun; instead, eclipse enthusiasts can use eclipse glasses, construct pinhole viewers, build pinhole projectors or even shape their fingers to project a view of the eclipse.
It's also important to avoid looking at the sun with a telescope or camera viewfinder without a solar filter, and to avoid looking through a telescope with eclipse glasses on, as the concentrated light could hurt the glasses. Read more at Space.com.
On a single day in August, the sun will disappear behind the moon, and sky watchers in the eclipse's path across 14 states from Oregon to South Carolina will witness a total solar eclipse.
Monday, August 21, will mark the first total eclipse in the United States since 1979. And it's been even longer since the last total solar eclipse to cross from the Pacific to the Atlantic: That occurred June 8, 1918, when an eclipse crossed from Washington to Florida.
