NASA tweeted that the first US city to witness the unusual event, which has been branded by hardline evangelical Christians as a sign of the end of the world, would be the US city in Oregon.

Of course, the US space agency does not believe anything untoward will happen during or after the eclipse, and has set up a base in the city to use high-tech equipment to capture stunning images of the eclipse.

NASA tweeted: “The eclipse's path will stretch from Salem, Oregon to Charleston, South Carolina.

“Observers outside this path will still see a partial solar eclipse.”

This month’s solar eclipse, known as the “Black Moon” by followers of the Wicca religion, will be the first in more than a century to travel all the way from the east coast to the west coast of America,

Yet, several online conspiracy theories have caused panic among believers that an apocalypse will follow the event.
