A new online tool gives eager skywatchers a preview of the Aug. 21 total solar eclipse.


Google and the University of California, Berkeley, have teamed up to create an interactive simulation of the highly anticipated event, which will be the first total solar eclipse visible from the United States mainland since 1979.


You can type your hometown or zip code into the simulator and see how much of the sun will be blotted out by the moon, as well as how the sun will travel across the sky over a 3-hour period on Aug. 21. [Total Solar Eclipse 2017: When, Where & How to See It (Safely)]


“There are lots of online animations of the 2017 eclipse, but you can’t use them like ours to get a sense of the full experience, including your surroundings,” project team member Dan Zevin, of UC Berkeley’s Space Sciences Laboratory, said in a statement. “Our simulation is closer to what one might experience in a planetarium show.”


The simulator is part of the Eclipse Megamovie Project, a Google-UC Berkeley effort that aims to collect and stitch together thousands of photos of the Aug. 21 eclipse taken by volunteer photographers around the country.

During the Aug. 21 eclipse, the moon will completely blot out the sun for observers in 12 states, from Oregon to South Carolina. More than 200 million people live within one day’s drive of the “path of totality” — the roughly 70-mile-wide (113 kilometers) strip from which a total eclipse will be visible — according to Space.com skywatching columnist Joe Rao.

The rest of North America, along with parts of South America, Europe and Africa, will witness a partial eclipse.


Remember: You can safely observe a total solar eclipse without eye protection, but only during the brief totality phase (which will last less than 3 minutes on Aug. 21, no matter where you happen to be). So be very careful. At all other times — even during the partial-eclipse phase — viewing the sun without special eclipse glasses, No. 14 welder’s glass or solar filters (if you’re using a telescope) can cause serious and permanent eye damage.
