For the solar eclipse of 2016, the Exploratorium was on the island of Woleai, in Micronesia, with multiple telescopes trained on the sun. These telescopes were connected to a laptop holding custom-made software that looks at the movement of the moon and the brightness of the sun. Composer Wayne Grim used this software to create a live composition based on the data. The musical composition uses rotational and orbital periods of the Earth, moon, and sun as formal elements.

Guillermo Galindo’s artistic work sweeps across musical boundaries, flowing from symphonic compositions to performance art installations and beyond. For Resonance, Galindo and his ensemble will perform "Resonant Shadows/ Circular Calls" on instruments made from immigrants’ personal belongings found along the border between Mexico and the United States. The artist’s musical sculptures—made with abandoned clothing, animal bones, bullet casings, a truck tire, and small, evocative ephemera such as a toothbrush or comb—and original scores form part of Border Cantos, an exhibition made in collaboration with celebrated photographer Richard Misrach, opening at the San Jose Museum of Art on February 25, 2016.

At the center of each chlorophyll molecule sits one magnesium ion, a linchpin for photosynthesis. Our cells require magnesium for hundreds of enzymes and metabolic processes. Spawned from supernovae and scattered through interstellar dust, this life-giving alkaline earth metal readily reacts and is abundant in seawater and a host of minerals from dolomite to olivine.

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.

In this video, Exploratorium Senior Scientist Paul Doherty explains why you rarely see a true scale model of the Earth, sun, and moon. Understanding the true scale of the solar system helps us appreciate the rarity of total solar eclipses: it’s unusual when objects at such distances line up perfectly.

Únete a la astrónoma del Exploratorium Isabel Hawkins quien junto a la educadora del Exploratorium Liliana Blanco explican los movimientos de los astros durante un eclipse total de sol. A través de demostraciones, ellas muestran cómo la luna, el sol y la Tierra se alinean para crear la coincidencia cósmica que llamamos un eclipse total de sol.
