We experience total solar eclipses because of the cosmic coincidence that the moon is 400 times closer than the sun and 1/400th of its size. We are not trying to scaremonger, but c'mon, guys. But before totality ends (after about 2 minutes, depending on your location), put your glasses back on to watch the rest of the event. Then you can take your glasses off to see the spectacle and the sun's corona. If you are within the path of totality, wear your glasses until the moon completely blocks the sun. To recap: If you are outside the path of totality, you must wear glasses the entire duration of the eclipse.
Eclipse glasses are also available at many libraries. Regular sunglasses are not good enough! NASA has identified several manufacturers of eclipse glasses and solar filters that meet international safety standards. Only specially designed solar filters will do the trick. Ultraviolet rays from the sun can literally give your eyeballs a sunburn. If you attempt to look at the eclipse without protective lenses, you risk severe damage to your eyes. This is also true if you are watching the eclipse from outside the path of totality. Yes! Except during the brief phase of totality, you must wear eclipse-watching glasses the entire time you are looking at the sun.

Free eclipse-viewing glasses will be available many places in the city, including the University of South Carolina campus, which is an official NASA viewing location.

In the path of totality, Columbia, S.C., is planning a full weekend of festivities in the days leading up to Aug. Eclipse enthusiasts can also head to the Udvar-Hazy Center in Chantilly for similar programming. You can also snag a pair of eclipse-viewing glasses at the museum, or learn to build a pinhole camera that will let you safely observe the sun. The Smithsonian will have solar telescopes set up for viewing the event. 21, head to the National Air and Space Museum. Here are the cities with the best chance of clear skies during totality. There, The Washington Post's Capital Weather Gang has you covered. It's also worth considering where you are least likely to experience clouds. Here's a look at some of the festivals taking place across the country on the big day. But several cities along the path are putting on a special show for the occasion. That means that researchers positioned at various locations along the path of totality can film the event and piece their clips together to create an unprecedented 90-minute video of the corona in action.Īnyone within the path of totality will be able to see the moon cover up the sun. Because this eclipse will move across thousands of miles of mostly inhabited landscapes, rather than hard-to-reach wilderness or open seas, it will be within sight of scientists for almost the duration of totality. The corona, which becomes visible when the moon covers up the sun, is the object of intense scientific interest - it emits sprays of hot, ionized particles that can damage electrical grids and satellites and harm astronauts in space. This eclipse is also a huge opportunity for scientists. It's likely to be a tremendous astronomical experience, and you don't want to miss it. An estimated 12 million people live in the path of totality, and as many as 7 million more will migrate to the path for the big event. For most Americans, this is the best chance to see a solar eclipse we will have in our lifetimes. This is the first total solar eclipse to occur solely in the United States since the country was founded. It should be called something else.” He recommends that everyone who is interested in the eclipse make their way to the path of totality for the big event. “It's a completely different phenomenon,” said Kentrianakis, of AAS. Veteran eclipse chasers say that a partial eclipse isn't nearly as beautiful as totality. If you are watching a partial eclipse, you must wear protective glasses for the entire event, or you will risk severe eye damage. People in the Washington area can expect to see about 80 percent coverage of the sun, starting just after 1 p.m. The degree to which the sun is covered depends on your proximity to the path of totality - the closer you are, the less of the sun you will see. They will see the sun partly covered by the moon - like a cookie with a bite taken out of it. But the moon also casts a lighter shadow, called the “penumbra.” People in this region, which will cover all of North America, will experience a partial eclipse. The shadow of the moon, known as the “umbra,” will cross a relatively small swath of land.
