"I don't how true it is that somebody was hoping to give birth during the eclipse, but I don't know how that will happen".

Adler Planetarium Director of Public Observing Michelle Nichols discusses the upcoming total solar eclipse at McHenry County College Tuesday, Aug. 8. NASA researchers are taking advantage of the opportunity to try to answer a number of science questions. And when sunlight was completely blocked during one eclipse, scientists in Mexico observed orb spiders tearing down their webs. But any deviation from that timing will be attributable to our lack of understanding for the size of the sun.

Measuring temperature perturbations during the eclipse will help NASA understand the dynamics of the Earth's atmosphere. The outermost layer of the sun, known as the corona, is hard to study because it's less bright than the rest of the sun - so we have trouble seeing it amid the rest of the sun's brightness. This allows the moon to perfectly block the sun's disk, while also showing us the corona.

In the centuries that followed, solar eclipses continued to be seen as harbingers of disaster or death. They're also the human response. Although the corona itself doesn't produce enough radiation to harm the retina, the seconds before and after the total eclipse can produce enough light intensity to be harmful. If weather is cloudy, most viewing events will provide a live NASA stream of the eclipse inside. While Wisconsinites won't witness a full eclipse, you'll still need "eclipse glasses", or some type of other viewer to safely look directly at it.

One source told Business Insider that she had nearly purchased a five-pack of eclipse glasses on Amazon, before double checking the date - and realizing that they wouldn't arrive until September.

Alderson said that eclipse watchers can test their glasses by holding them up to the sun and looking thorough them briefly. Or I have here a strip of material that I got from the Orion telescope company.

There are alternative methods to indirectly view the partially eclipsed sun. Illinois State Police anticipate many people will hit the roads to see the eclipse in its totality.

NASA warned in July that sellers were offering faulty eclipse glasses while claiming they were legitimate.

These stores are selling official ISO approved glasses.

Safe eclipse glasses should be stamped with a label indicating they meet the worldwide "ISO 12312-2" standard - although Fienberg said counterfeiters have also started to print that on fake glasses. We've posted a link at During an eclipse, astronomers get an exceptional chance to study the photosphere "just up to a hundred miles from the sun's surface", she said. Major retailers such as 7-Eleven, Best Buy, Kroger, Walmart, Toys "R" Us, and more were also included. If you glance at the sun through your glasses, for example, and find it uncomfortably bright, out of focus and surrounded by a murky haze, they're no good.
