On Monday, August 21, 2017, all of North America will see an eclipse of the sun. It is the first total solar eclipse to cross the nation in ninety-nine years! Now, you may be unaware of what a total solar eclipse is. There are different types of eclipses. However, this type is when the moon moves between the sun and the earth. The eclipse lasts up to three hours. During the eclipse, the moon will completely cover the sun and the sun’s atmosphere and the corona can be seen. The eclipse might be dangerous. NASA says that looking directly at the eclipse isn’t safe for your naked eye, it could burn your retinas. There’s an easy fix for that, just use tree shadows. Rick Fienberg, a press officer for the American Astronomical Society, stated, “Find a nice leafy tree and look under it during the partial phases of the eclipse”. The total eclipse can not be seen from everywhere. People in Oregon, Idaho, Montana, Wyoming, Nebraska, Kansas, and Idaho will be able to see it. The eclipse can also only be seen at specific times depending on where you live. Since we won’t be able to see it in Arizona, you can watch the live video streams on http://www.nasa.gov/eclipselive.
