So the moon, sun, far apart, but they look like they are the same size. Two of NASA's WB-57F research jets, armed with telescopes, will be used to chase the eclipse at a precise speed that will allow scientists to observe it for 3 times longer than usual - that's over 7 minutes of solar goodness.
Cantore and Abrams will anchor live coverage of the eclipse as it crosses the country over the course of the day. You will also have to consider travel times and costs and availability of lodging as well as plan for large crowds on eclipse day.
You can join the party on August 21 from 1 to 3 p.m.at the Palmyra Cove Nature Park Environmental Discovery Center, Route 73, for the opportunity to view one of nature's most stunning displays. Special safety glasses are needed to view the event, which will be provided at each school. The glasses will be available to attendees at the event on a first-come, first-served basis, Library Director Jackie Icenhower said, and won't be handed out in advance. While the path of totality is quite small, the eclipse will be visible in part from a much wider area.
We've mapped out the best places with high vantage points and great views of the sky that will give you a clear view of the partial eclipse (if Karl plays nice, that is). Tennessee Nashville hasn't had a total solar eclipse since July 29, 1478. The path of totality will create a 70-mile wide path from OR to SC, the rest of the country will see various amounts of coverage. It's expected that here, the sun will be eclipsed by approximately 80 percent. Get yourself solar eclipse glasses now. The library's website says "The Watcher in the Woods" should end by 2:30 p.m.
Have certification information with a designated ISO 12312-2 worldwide standard.
Not be used if they are older than three years, or have scratched or wrinkled lenses.
NASA has a list of certified retailers, and the American Astronomical Society has its own list of solar filter manufacturers and retailers.
Ordinary sunglasses - even very dark ones - should not be used as a replacement for eclipse viewing glasses or handheld solar viewers.
According to experts at NASA, one popular theory is that the bands originate in the atmosphere due to highly unpredictable air cells that help to "focus and de-focus the sharp-edged light from the solar surface".
"It's something you remember your entire life, and you will tell stories to your grandchildren about it", Espenak added.
