New Delhi:

A total solar eclipse will take place on August 21, across the entire United States. Crossing the country from Oregon to South Carolina over the course of an hour and a half, 14 states will experience night-like darkness for approximately two minutes in the middle of the day.

The eclipse enters the U.S. at 10:15 a.m. PDT off the coast of Oregon and leaves U.S. shores at approximately 2:50 p.m. EDT in South Carolina. 

All of North America will experience at least a partial eclipse.

Users now  record observations with a free app with NASA’s Global Learning and Observations to Benefit the Environment (GLOBE) Program Observer (NASA GO) which is a citizen science project 

For the first time in almost a century the United States is preparing for a coast-to-coast solar eclipse, a rare celestial event millions of Americans, with caution, will be able to observe.

During the eclipse on August 21 -- the first of its kind since 1918 -- the moon will pass between the sun and Earth, casting a dark shadow and making visible the sun’s normally obscured atmosphere, or solar corona, as well as bright stars and planets.

Observers will be able to see the moon’s 70-mile wide shadow from Oregon in the west to South Carolina in the east over the course of more than two daylight hours, with two minutes of darkness engulfing 14 states.

Almost 12 million Americans live within this strip of the country, while some two-thirds of the nation’s population reside within a day’s car ride, said Martin Knopp of the Department of Transportation.

The US will be the only country to experience the total eclipse, and international visitors are expected to descend for the event.

Spacecraft, NASA aircraft, more than 50 high-altitude balloons and astronauts aboard the International Space Station will capture images.

“Never before will a celestial event be viewed by so many and explored from so many vantage points—from space, from the air, and from the ground,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington.

A total eclipse has not covered regions of the contiguous US since 1979. There will be another in 2024, which will cover regions of the country from Texas to Maine.

NASA will broadcast live video of the cosmic event, and watch parties are expected to be held in parks, libraries and stadiums nationwide.

The continental US outside of the total eclipse strip will experience a partial solar eclipse, according to Rick Fienberg, a spokesman for the American Astronomical Society.

NASA has strongly cautioned against directly looking with the naked eye at the sun outside of the total eclipse window.

The only method to safely observe a partially eclipsed sun is with eclipse glasses or handheld solar viewers, the US space agency said—ordinary sunglasses are not enough.

And according to Fienberg, even a 99 percent partial eclipse is not nearly as awe-provoking as the total eclipse event.

“It’s literally the difference between day and night,” he said.

“Going through life without ever experiencing ‘totality’ is like going through life without ever falling in love.”
