On August 21, 2017, NASA EDGE will join forces with the NASA Heliophysics Education Consortium, the University of Southern Illinois Carbondale, and Lunt Solar Systems to air a 4-hour 30-minute live webcast of the total solar eclipse from outside Saluki Stadium at Southern Illinois University Carbondale in Illinois. The webcast will begin airing at 11:45 AM EDT (3:45 PM UTC). During course of the Megacast, NASA EDGE will be tracking the eclipse as it starts in Oregon and makes its way across the country ending in South Carolina. You will be introduced to some of the leading experts in the field of Heliosphysics and learn all about the Sun-Earth Connection. Lunt Solar Systems will be providing high resolution and stunning imagery of the eclipse in three different wavelengths of light: Hydrogen-Alpha, Calcium-K, and white light. Oh by the way, you will experience a scientific balloon launch from inside Saluki Stadium, observe several science demonstrations, learn how you can become a citizen scientist, and engage with subject matter experts through social media. So if you're unable to view the eclipse in person, don't worry. Sit back, relax and let NASA EDGE turn your location into the best seat in the house!
Additional streams coming soon!
Stay up-to-date with the latest information from our eclipse community through a variety of social media channels. Social media icons can be located on every page of this website.
In addition, the following social media venues will remain very active before, during and after the event!
THE SUN TODAY
Prepare a variety of activities for your attendees. You can often find great activities and materials at local clubs, schools, and museums. Eclipse activities often include storytelling and/or arts and crafts. You can also find a wide selection of recommended activities online. Below are just a few to get you started:
Visit our Eclipse Mobile Apps page for a growing list of apps.
Visit our ‘Downloadables’ page for a growing list of eclipse materials (bookmarks, posters, etc.) that you can download and print!
NASA has produced several video clips that explain eclipses and how NASA is planning to study this eclipse. They can be downloaded in various sizes and formats.
NASA Previews 2017 Total Solar Eclipse: The Path of Totality across the USA is represented. On August 21, 2017, the moon will pass between the sun and Earth in alignment that will cast the moon’s shadow, 170 miles wide, onto Earth.
2017 Eclipse Shadow Cones: The umbral and penumbral shadow cones travel across the surface of the Earth during the August 21, 2017 total solar eclipse.
2017 Eclipse and the Moon’s Orbit: Solar eclipses can only occur at New Moon, when the Moon is between the Earth and the sun. But not every New Moon produces an eclipse. The Moon's orbit is slightly tilted, and as seen in this animation, the tilt causes the Moon's shadow to miss the Earth during most New Moons—about five out of six, in fact.
2017 Total Solar Eclipse in the U.S.: A view of the United States during the total solar eclipse of August 21, 2017, showing the umbra (black oval), penumbra (concentric shaded ovals), and path of totality (red) through or very near several major cities.
2017 Eclipse: Earth, Moon, Sun: A solar eclipse occurs when the Moon passes between the sun and the Earth, casting its shadow on the Earth. The shadow comprises two concentric cones called the umbra and the penumbra. Observers on the Earth who are within the smaller, central umbra see the sun completely blocked. Within the larger penumbra, the sun is only partially blocked.
People will have all sorts of questions about the eclipse and, most likely, about a wide range of astronomy topics, so be prepared to spend some of your time just answering questions. The following resources will help you with that task:
An eclipse is a rare and striking phenomenon you won't want to miss, but you must carefully follow safety procedures. Don't let the requisite warnings scare you away from witnessing this singular spectacle! You can experience the eclipse safely, but it is vital that you protect your eyes at all times with the proper solar filters. No matter what recommended technique you use, do not stare continuously at the sun. Take breaks and give your eyes a rest! Do not use sunglasses: they don't offer your eyes sufficient protection. Visit our SAFETY page for more information.
Observers should be made aware of the times of ingress and egress and prompted with time updates every 10-15 minutes. For solar eclipses, announcements of the totality times (1st, 2nd, 3rd, and 4th contact) should be made. Here it is especially important to sound an alarm maybe 15 seconds before totality ends so that people are not caught looking at or photographing the eclipse without solar filters when the sun reemerges from behind the moon.
Share the resources on this website with your local school districts or after school groups. Work with teachers to prepare students who you invite to your eclipse party.
Pre-Eclipse Party – If hosting an event on the day of the eclipse isn't possible, consider hosting your party before the eclipse to prepare your audience for the live webcast.
Post-Eclipse Party – An edited copy of the live webcast will be available within hours after the eclipse. It's the perfect addition to those of you who might want to host a party after the event.
Hosting a contest can be a great way to get people excited about your launch party. You can announce the winners at your party, and offer a small prize to incentive people if you so choose. Here are a few potential ideas for contests:
