On Monday, a total solar eclipse will be viewable in the United States, from coast to coast. A total solar eclipse occurs when the moon passes in between the Earth and the sun, casting a shadow that blocks the sun’s light. The last total eclipse of the sun that could be seen across the United States occurred 38 years ago, on February 26, 1979.
This exciting event can be viewed first in Oregon just after 12:00 p.m. ET, reaching its first totality point at 1:15 p.m. near Salem, Oregon. The partial phases of the eclipse can last about 90 minutes, but the duration of the total eclipse of the sun can last about 2 minutes at its longest duration point. The lunar shadow will leave the United States completely just after 4:00 p.m. ET in South Carolina. Don’t forget about eye safety!
The map shows where the total solar eclipse on 21 août 2017 is visible. You can select any location to see when the eclipse starts and ends, and how much of the Sun is obscured there.
There is no way you can stop today’s total solar eclipse from happening. It is celestial, and we have no control over it. The only way to stop it would be to extinguish the sun or knock the moon or Earth out of orbit.
Millions are forecast to flock to the very narrow — 70 miles wide — swath that hugs the country like a belt.
“This will be like Woodstock 200 times over — but across the whole country,” said Alex Young, a solar scientist at NASA’s Goddard Space Flight Center.
The Federal Highway Administration is calling this a “planned special event for which there has been no recent precedent in the United States.”
The moon, which many of us often take for granted, will quite literally have its day in the spotlight.
In this celestial dance, the moon moves perfectly in between the Earth and the sun. During a total solar eclipse, the moon and the sun both appear to be about the same size from the ground.
