2017 Eclipse: Earth, Moon and Sun

B-roll for August 21st Eclipse, filmed at NASA s mall and visitor center. || On Monday, Aug. 21, all of North America was treated to one of the rarest celestial events – a solar eclipse. Members of the public came out to NASA’s Goddard Space Flight Center’s Visitors Center to experience the partial and chat NASA scientists about this unique event.During the eclipse, 14 states across the U.S. were in the path of totality and experienced more than two minutes of darkness in the middle of the day – with a partial eclipse viewable all across North America. The eclipse’s long path over land provided a unique opportunity to study the Sun, Earth, Moon and their interaction.Solar eclipses happen somewhere in the world about every 18 months, but much of the time it happens over the ocean. To have an eclipse travel across so much land where millions of people live is incredibly rare, and makes for a unique opportunity for so many to witness one of nature’s most impressive shows.Still images from Earth and science satellites will be uploaded/available at https://flic.kr/s/aHsm21Mytv.Images sent in by the general public will be uploaded/available at https://www.flickr.com/groups/nasa-eclipse2017/.

Canned interviews and b-roll will be available here starting Tuesday, August 15, at 6:00 p.m. ET. || Are you ready for the historic solar eclipse that’s just days away?Do you have what you need to see it safely?You can see the eclipse no matter where you are in North America on Aug. 21!August 21 will be a day for the history books. No matter where you are in North America, you’ll get to experience the first coast-to-coast solar eclipse in nearly a century! The dark shadow of the moon will sweep from Oregon to South Carolina, putting 14 states in the path of totality and providing a spectacular view of a partial eclipse across all 50 states.Eclipses are an incredible experience, but it’s important to view them safely. Join NASA scientists on Wednesday, August 16, from 6:00 a.m. – 12:30 p.m. ET and again from 3:00 p.m. – 8:00 p.m. ET to show your viewers what they need to safely see the eclipse whether they’re inside the path of totality or not. You should never look directly at the sun! The only safe way to look directly at the sun or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers. An eclipse is a striking phenomenon you won t want to miss, but you must carefully follow safety procedures.Solar eclipses happen somewhere in the world about every 18 months, but much of the time it happens over the ocean. To have an eclipse travel across so much land where millions of people live is incredibly rare, and makes for a unique opportunity for so many to witness one of nature’s most impressive shows. It’s also a great opportunity for scientists to see the sun’s faint outer atmosphere and evaluate how Earth responds to the sudden darkening.Take this opportunity to step outside and safely watch one of nature’s best shows!*** To book a window ***Contact Michelle Handleman michelle.z.handleman@nasa.gov / 301-286-0918HD Satellite Digital Coordinates for G17-K20/Up: Galaxy 17, Ku-band Xp 20, Slot Upper | 91.0 ° W Longitude | DL 12109.0 MHz | Vertical Polarity | QPSK/DVB-S | FEC 3/4 | SR 13.235 Mbps | DR 18.2954 MHz | HD 720p | Format MPEG2 | Chroma Level 4:2:0 | Audio EmbeddedSuggested Questions:1.

The August 21 solar eclipse provides a unique opportunity to study our planet and what happens when Earth goes dark during an eclipse. It’s also an opportunity for what may be the largest citizen science project of all time.On that Monday, the moon’s shadow will darken the sky, causing temperatures to drop and stars to become visible in the normally day lit sky. This brief hiccup in the usual day-night cycle changes the amount of energy an area gets from the sun.NASA scientists hope to learn just how much Earth’s environment changes during this historic eclipse and they need help from your viewers! Using the GLOBE Observer phone application, curious eclipse onlookers can become citizen scientists.

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.

Insolation (the amount of sunlight reaching the ground) is affected dramatically by the Moon s area covered by the Moon, is calculated at 10-second intervals from 16:25:40 to 20:25:30 UTC at a resolution of 360/8192 degrees per pixel (roughly 3.75 ), with white = 100% obscuration and black = 0%. The sharp borders are the terminator (the day-night line). The complete dataset can be downloaded as a single .zip file (196 MB).

The August 21, 2017 total solar eclipse as seen from a satellite in orbit around L1, a point about 1.5 million kilometers from Earth in the direction of the Sun. || A number of satellites will be watching the August 21, 2017 total solar eclipse from space. One of them, the Deep Space Climate Observatory (DSCOVR) will see the eclipse from its orbit around L1, the Lagrange point located about 1.5 million kilometers from Earth along the Earth-Sun line. From this vantage point, DSCOVR s orbit takes it several degrees off both the Sun-Earth line and the Sun-Moon line. For the same reason, the Moon will not be in the frame. The animation places the virtual camera in a plausible position for DSCOVR. The actual position of the spacecraft at the time of the eclipse will be affected by adjustments to its orbit that may be made in the coming months.EPIC has already captured the total solar eclipse of March, 2016.

LEAD: NASA scientists and astronomers are already planning for the first total solar eclipse for the United States in 38 years. 1. On August 21, 2017, the moon will pass between the sun and Earth in an alignment that will cast the moon s shadow onto Earth. 2. A dark shadow of the moon, 170 miles wide, will sweep across the U.S. over the course of one-and-a-half hours. 3. People in cities lying within the narrow path of the shadow (red line in the video) will experience an eerie sense of twilight as day turns to night and back to day again within roughly 2-2.5 minutes. TAG: Solar astronomers will use the solar eclipse to study the outer atmosphere of the sun.

This version includes images of the Sun showing its appearance in a number of locations, each oriented to the local horizon.

The umbral and penumbral shadow cones travel across the surface of the Earth during the August 21, 2017 total solar eclipse. || A solar eclipse occurs when the Moon s shadow falls on the Earth. The shadow comprises two concentric cones called the umbra and the penumbra. Within the smaller, central umbra, the Sun is completely blocked by the Moon, and anyone inside the umbra sees a total eclipse. Within the larger penumbra, the Sun is only partially blocked.In this animation, the umbra and penumbra cones are viewed through a telescopic lens on a virtual camera located far behind the Moon. Long focal lengths like the one used here appear to compress the distance between near and far objects. Despite appearances, the geometry of the scene is correct. The Earth is roughly 112 lunar diameters beyond the Moon, and the angle at the apex of the umbral cone is only about half a degree.From this point of view directly behind the Moon, the edges of the shadow cones look circular. The edge of the penumbra is outlined in yellow. It passes over all of North and Central America and the Amazon basin, as well as Greenland and the North Pole. Everyone there will see at least a partial eclipse. The path of the umbra (the small black dot) crosses the United States from Oregon to South Carolina.

The Moon orbits the Earth in the months prior to the August 21, 2017 total solar eclipse. Viewed from above, the Moon s shadow barely reaches the Earth as it traces a path across North America. || The Moon orbits the Earth in the months prior to the August 21, 2017 total solar eclipse.
