On August 21, 2017, daylight will fade to the level of a moonlit night as millions of Americans experience one of nature’s most awe-inspiring shows – a total solar eclipse. For the first time since 1918, the dark shadow of the moon will sweep coast-to-coast across the United States, putting 14 states in the path of totality and providing a spectacular view of a partial eclipse across all 50 states.
NASA scientists are available Wednesday, June 21, from 6:00 a.m. – 12:00 p.m. ET to show your viewers the path of the eclipse, what they need to see it safely and talk about the unprecedented science that will be gathered from one of the most anticipated and widely observed celestial events in history. We’ll also give your viewers a sneak peek of a press conference about the eclipse NASA is having later that day.
A solar eclipse happens when a rare alignment of the sun and moon casts a shadow on Earth. NASA knows the shape of the moon better than any other planetary body, and this data allows us to accurately predict the shape of the shadow as it falls on the face of Earth. While everyone in the U.S. will see the eclipse if their local skies are clear, people standing in the path of totality – completely in the moon’s shadow – will see stars and planets become visible in what is normally a sunlit sky.
Eclipses provide an unprecedented opportunity for us to see the sun’s faint outer atmosphere in a way that cannot be replicated by current human-made instruments. Scientists believe this region of the sun is the main driver for the sun’s constant outpouring of radiation, known as the solar wind, as well as powerful bursts of solar material that can be harmful to our satellites, orbiting astronauts and power grids on the ground.

Suggested Questions:
1. This is the first time in nearly 100 years that the United States will have the opportunity to see a total solar eclipse coast-to-coast! What will happen on August 21?
2. This eclipse will be the most widely observed and shared celestial event in U.S. history. Why are scientists excited for this eclipse?
3. Eclipses allow scientists to see the sun’s faint outer atmosphere, which is actually hotter than its surface. What can you tell us about NASA’s upcoming mission that will touch the sun?
4. How does NASA’s study of our sun help us explore the solar system?
5. How does NASA’s mapping of the moon give us the accurate path of totality?
6. Where can we learn more?

Representatives from NASA, other federal agencies, and science organizations, will provide important viewing safety, travel and science information during two briefings at the Newseum in Washington starting at 1 p.m. EDT Wednesday, June 21.The event will air live on NASA Television and stream on the agency’s website.Over the course of 100 minutes, 14 states across the United States will experience more than two minutes of darkness in the middle of the day. Additionally, a partial eclipse will be viewable across all of North America. The eclipse will provide a unique opportunity to study the sun, Earth, moon and their interaction because of the eclipse’s long path over land coast to coast. Scientists will be able to take ground-based and airborne observations over a period of an hour and a half to complement the wealth of data and images provided by space assets.The June 21 briefings are:Logistics Briefing: 1 to 2 p.m.Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate at the agency’s headquarters in WashingtonVanessa Griffin, director of the National Oceanic and Atmospheric Administration’s Office of Satellite and Product Operations in Suitland, MarylandBrian Carlstrom, deputy associate director of Natural Resource Stewardship and Science at the National Park Service in WashingtonMartin Knopp, associate administrator of the Office of Operations in the Federal Highway Administration at the U.S. Department of Transportation in WashingtonScience Briefing: 2:30 to 3:30 p.m.Thomas ZurbuchenAngela Des Jardins, principal investigator of the Eclipse Ballooning Project at Montana State University, BozemanAngela Speck, professor of astrophysics and director of astronomy at the University of Missouri, ColumbiaDave Boboltz, program director of solar physics in the Division of Astronomical Sciences at the National Science Foundation in Arlington, VirginiaLinda Shore, executive director of the Astronomical Society of the Pacific in San FranciscoMatt Penn, astronomer at the National Solar Observatory in Tucson, Arizona || ",

"title": "How to Safely Watch a Solar Eclipse",
"description": "It is never safe to look directly at the sun's rays – even if the sun is partly obscured. When watching a partial eclipse you must wear eclipse glasses at all times if you want to face the sun, or use an alternate indirect method. This also applies during a total eclipse up until the time when the sun is completely and totally blocked.During the short time when the moon completely obscures the sun – known as the period of totality – it is safe to look directly at the star, but it's crucial that you know when to take off and put back on your glasses.First and foremost: Check for local information on timing of when the total eclipse will begin and end. NASA's page of eclipse times is a good place to start. Second: The sun also provides important clues for when totality is about to start and end.Learn more at https://eclipse2017.nasa.govFind more videos about the solar ecilpse on the Sun Eclipse 2017 gallery page. || ",

The umbra is shown at 3-minute intervals, with times in the local time zone at the umbra center. The duration of totality is outlined in 30-second increments. Interstate highways are blue, other major roads are red, and secondary roads are gray.Some sources list only 12 states for this eclipse, but in fact the path of totality also grazes the southwestern borders of both Montana and Iowa. The Montana part of the path is in a roadless area at the southern end of the Beaverhead Mountains, a range that defines sections of both the Montana-Idaho border and the Continental Divide. The Iowa part of the path is west of Interstate 29 near Hamburg, south of 310 Street, and bounded on the west by the Missouri River. It includes the Lower Hamburg Bend Wildlife Management Area. || ",

"description": "On Feb. 11, 2010, NASA launched an unprecedented solar observatory into space. The Solar Dynamics Observatory (SDO) flew up on an Atlas V rocket, carrying instruments that scientists hoped would revolutionize observations of the sun. If all went according to plan, SDO would provide incredibly high-resolution data of the entire solar disk almost as quickly as once a second. When the science team released its first images in April of 2010, SDO's data exceeded everyone's hopes and expectations, providing stunningly detailed views of the sun. In the three years since then, SDO's images have continued to show breathtaking pictures and movies of eruptive events on the sun. Such imagery is more than just pretty, they are the very data that scientists study. By highlighting different wavelengths of light, scientists can track how material on the sun moves. Such movement, in turn, holds clues as to what causes these giant explosions, which, when Earth-directed, can disrupt technology in space. SDO is the first mission in a NASA's Living With a Star program, the goal of which is to develop the scientific understanding necessary to address those aspects of the sun-Earth system that directly affect our lives and society. NASA's Goddard Space Flight Center in Greenbelt, Md. built, operates, and manages the SDO spacecraft for NASA's Science Mission Directorate in Washington, D.C.SDO: Year One here.SDO: Year 2 here.Information about the individual clips used in this video is here.Watch this video on YouTube. || ",
