The total solar eclipse will be captured and broadcast live by NASA beginning at 7 p.m. CST Tuesday. In a release the National Aeronautics and Space Administration said it will partner with the Exploratorium Science Center in San Francisco to host activities around Tuesday’s total solar eclipse including chances to speak to solar scientists and live coverage of the eclipse originating from Woleai island in Micronesia.
NASA will also provide a Reddit Ask Me Anything session with scientists from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, at noon Tuesday.
The projected period of total eclipse, called totality, will occur from 8:38 p.m. to 8:42 p.m. and will be broadcast on NASA Television (nasa.gov/multimedia/nasatv/index.html).
According to the release, Twitter, Google+ and Facebook users will be able to join the conversation and ask questions using the hashtag #eclipse2016. NASA’s Twitter account for the eclipse is @NASASunEarth.
The total eclipse will be visible in parts of South East Asia and a partial eclipse will be visible in parts of Alaska, Hawaii, Guam and America Samoa.
NASA said an eclipse occurs when the moon passes directly between Earth and the sun. When the moon’s shadow falls on Earth, observers within that shadow see the moon block a portion of the sun’s light.
