|On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun. Anyone within the path of totality can see one of nature’s most awe inspiring sights – a total solar eclipse. This path, where the moon will completely cover the sun and the sun’s tenuous atmosphere – the corona – can be seen, will stretch from Salem, Oregon to Charleston, South Carolina. Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun’s disk. NASA created this website to provide a guide to this amazing event. Here you will find activities, events, broadcasts, and resources from NASA and our partners across the nation.
It is critical to know the safe way to “look at the sun” during the upcoming Solar Eclipse. It is not true that because it is a “total” eclipse, there is no need for protective eye wear. Dangers of unprotected viewing of the sun, even for a few seconds, include short-term retinal bleaching and discomfort, and potential permanent blindness (i.e., solar retinopathy) after only a few minutes of unprotected viewing of the sun and solar eclipse. The human lens, and regular sunglasses, CANNOT successfully block direct sunlight, and it will create a permanent burn mark on the sensitive macula, which focuses the light. Any macular defect will create a permanent loss of central vision. Eclipse sunglasses need to meet the requirement of ISO. 12312-2:2015 for your best protection.
