This Monday, at 1:27 p.m. (9:27 p.m. in Albania), the sky will darken for millions of Americans during the solar eclipse.
This is the first solar eclipse to be visible across North America in seven years, and the next one won't be visible in these areas until Aug. 23, 2044, according to NASA.
Meanwhile, for those who live in states that will not see the eclipse, NASA will start the live broadcast from 19.00 to 22.00.
You can watch the footage on NASA's official YouTube channel.
In Europe, the eclipse will be partially visible in Norway, Iceland, Ireland, the western parts of Great Britain, the northwestern parts of Spain and Portugal, the Azores and the Canary Islands.
