See the highlights of totality from the total solar eclipse of March 8/9 2016! The Exploratorium and NASA went to Woleai, a tiny atoll in the Federated States of Micronesia, where we broadcast the eclipse live. Totality began at 11:38 a.m. on March 9 in Woleai, Micronesia, which was 5:38 p.m. on March 8 in San Francisco. Join Exploratorium scientists Paul Doherty and Isabel Hawkins for a live webcast as they share information about the Rosetta Mission, which is due to be "woken up" on January 20th, 2014. Rosetta is a spacecraft en route to Comet 67P/Churyumov-Gerasimenko, where it will make the most detailed study of a comet ever attempted. Exploratorium composer Wayne Grim used the video of the transit to create a sound composition in real time. As the video signal was received by Wayne's computer, a program he wrote converted the signal into a unique aural experience. http://www.waynegrim.com Video teaser for the upcoming launch of the new Exploratorium website, 'Never Lost'. Learn a little bit about Polynesian Navigation in anticipation of the full website On August 1, 2008, a total solar eclipse occurred as the new moon moved directly between the sun and the earth. The moon's umbral shadow fell on parts of Canada, Greenland, the Arctic Ocean, Russia, Mongolia, and China. The Exploratorium's eclipse expedition team (our fifth!) Webcast the eclipse live from the remote Xinjiang Uygur Autonomous Region in northwestern China near the Mongolian border. An introduction to the jitterbug, a simple motorized toy made of a recycled CD and a DC motor. A detailed demonstration of how to make this toy, including a discussion of materials needed. The science behind this toy, including a discussion of how electric circuits work, and how an unbalanced load (an off-center weight on your jitterbug) results in rotational vibration. On March 29, 2006, a total solar eclipse occurred as the moon moved directly between the earth and the sun. The moon's shadow fell on the earth, first darkening the eastern tip of Brazil, and then moved across the Atlantic Ocean to make landfall in Ghana, Africa. It continued moving northeast through Nigeria, Niger, Libya, Egypt, across the Mediterranean and into Turkey, where an Exploratorium team was waiting. Celebrate the spring equinox at the Mayan ruins of Chichén Itzá, in the state of Yucatan, Mexico. The alignment of the sun on this day creates the appearance of a shadow, in the form of a serpent, that descends the main staircase of the great pyramid. The Live@Exploratorium crew is there to capture the snake on film and to speak with local archaeologists, archeoastronomers, and solar scientists about this amazing phenomenon.
