McMurdo Station is the American staging area for Antarctic research. At the edge of Ross Island, off the coast of the continent, a small town of workeres feeds, houses, prepared, supplies, fuels, transports, and protects those who conduct field research throughout Antarctica and the surrounding waters. The community numbers 1,000 in the summer and 200 in the winter.
And the community has a garden. But they aren't allowed to use soil. 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. Join the Live@ crew and NASA scientists as we delve into the ancient knowledge of the Chacoans, daily sky watchers who amassed a great knowledge about the movements of the sun. And learn why today's astronomers and solar physicists continue to watch the sun, using modern ground-based observatories and orbiting space telescopes. Join us in Chaco Canyon to think about what we can learn from watching shadows.
The sun holds an honored place in the lives of Southwestern Native Americans. Hear insights into the importance of the sun from Dr. Shelly Valdez, educator at Laguna Pueblo; Dr. Isabel Hawkins, solar researcher at UC Berkeley; and Andrew Garcia Sr., coordinator of Tewa dancers.
