These livestreams are out of this world.

On August 21, the U.S. will experience the first total solar eclipse — when the moon covers the entire sun — visible from the continental U.S. since 1979. It will last almost three hours in some locations.

Residents of fourteen states, including northern Oregon, and central Wyoming, Missouri, and North Carolina, will see the “total” eclipse. Other regions will see partial eclipses, with 25-95% of the sun hidden. Manhattan will see 71% of the sun blocked, Los Angeles 62%.

You can check out NASA’s interactive map to see how much of the eclipse you’ll get to see from your location, as well as what time it will start, and how long you can expect it to last. And if you’re interested travelling to get a better view, Space.com has a list of the best places to see the eclipse, and things to do while you’re there.

But if, like many of us, you’ll be stuck at your desk for the duration of the eclipse, you can still view it from the office with these live streams:

NASA TV

The livestreams will be hosted and filmed by prominent astronomers, with film and photographs from locations across the country, and they’re all completely free. Nasa’s streams will feature many angles and locations. TimeAndDate’s will follow the path of the total eclipse across the country, and feature commentary from an astrophysicist. Astonomy.com’s will hail from Denver, Colo., which will experience 92% coverage.

And even over a livestream, be careful not to look directly at the sun, even if it’s partially eclipsed. Visit NASA’s Eclipse101 for more advice on how to view the eclipse safely.
