Visualize the Total Solar Eclipse with NASA's 3D App

Sunday, 13 Aug, 2017

While many have already made preparations for the event, here are some facts about the upcoming eclipse.

Total solar eclipses - when skies darken as the moon moves between the Earth and the sun - happen roughly every 18 months. "It will essentially be the same in Columbus".

NASA will host an Eclipse Megacast, providing unique coverage of the astronomical event that will include commentary from scientists and the public, as well as live footage of the phenomenon. The eclipse will peak, with the maximum surface of the sun covered, around 2:33 p.m., and that will last about two minutes and 31 seconds.

During a solar eclipse, such as the one that will happen on August 21, the moon comes between the Earth and the sun, blocking out the light of the sun. During totality, when the moon blocks the sun, it's safe to remove the filter so you can see the sun's outer atmosphere: the corona.

Unlike places like Hopkinsville, which will experience a total eclipse, areas like Evansville will only see a partial eclipse.

"There's only a handful". The eclipse this year will last no more than three minutes in its totality. "But, for one specific location on earth, it may be hundreds of years between events".

There are usually six or seven total solar eclipses per decade, somewhere in the world. When total eclipse begins in western OR, the partial eclipse will just be starting here in Baltimore. The rest of the nation and parts of North and Central America will experience a partial solar eclipse. Make sure you don't directly look at the sun during the eclipse unless you have special eye protection.

A customer who provided a copy of the email and a photo of the glasses says he bought the Thousand Oaks Optical Solar Viewers from third-party seller through Amazon. Sunglasses, even very dark glasses, are not safe for looking at the sun. The museum also plans to open its new "Buffalo in Space" science studio to coincide with the August 21 Great American Solar Eclipse.

"A lot of people think they can just use a filter on the eye-piece of their telescope but when the light comes through your telescope, it will burn out of the guts and literally light them on fire", she said.

"I'm surprised at how few Montana sites there are", she said.
