The Exploratorium has been bringing solar eclipses to world-wide audiences via live broadcasts since 1998. We'll be on site again to capture the 2016 Total Solar Eclipse from the remote Micronesian island of Woleai. Join us live from Micronesia on March 8, 2016 at 5 p.m. PST either online or at the Exploratorium’s free event! www.exploratorium.edu/eclipse/ We’ll also be broadcasting the 2017 eclipse; Stay tuned for more details!

Join Resonance host, Nicole Minor in conversation with performer, composer, and ethnomusicologist A.J. Racy. Dr. Racy ushered in the third season of Resonance on December 10th, 2015 with a range of compositions and improvisations that explore ancient modes and forms endemic to Middle Eastern cultures.

Recorded live at the Exploratorium in 2015. A noted foe of tooth decay, fluoride is added to most toothpaste, as well as our public water supply—a fact attacked by numerous conspiracy theories. Find out more about this controversial compound from Howard Pollick, Director of the Dental Public Health Residency Program at the University of California, San Francisco, and discover why elemental fluorine is considered to be completely dangerous, if not deadly.

Recorded live at the Exploratorium in 2015. Furiously reactive, fluorine has a ferocious appetite for attracting electrons from other elements, and a fearsome habit of killing chemists. Due to the strength of its bonds, fluorine is found almost exclusively in compounds such as the colorful mineral fluorite. Early attempts to isolate the element were met with injury and death from explosions, corrosive burns, and poisonous fumes. In 1886, the treacherous gas was at last isolated by Henri Moissan, whose innovative processes are still in use today.

Leaders in their respective fields of science and medicine, Anne Wojcicki, cofounder and CEO of 23andMe, and her sister Janet Wojcicki, PhD, MPH, and professor at the University of California, San Francisco, join Exploratorium Director Dennis M. Bartels, PhD, for a stimulating conversation about their work and the evolution of the role of women in science, medicine, and technology.

A little over five years after initial construction on the Exploratorium's new home at Piers 15-17 began, the installation of a 24' x 60' floating dock off the south Apron of Pier 15 took place in early November. The dock will provide Pier access for water taxis in the San Francisco Bay. Timelapse video captures the last of the Exploratorium's original project construction.

Recorded live at the Exploratorium 2015. Earth, water, air, fire: our world is ruled by oxygen, the third most abundant element in the universe. Originating inside of stars, oxygen is scarce on planets outside our own. It comprises roughly half the mass of Earth’s crust and a fifth of its atmosphere. Nonmetallic and highly reactive, oxygen is key to combustion and corrosion, and forms stable bonds with almost every element, notably hydrogen (H2O) and itself.

Recorded live at the Exploratorium in 2015. Earth’s oxygen is produced in equal measure by terrestrial vegetation and microscopic life in the sea. Explore the profound influence of phytoplankton on the atmosphere with Exploratorium scientist Jennifer Frazier, and learn how their populations are changing along with our climate. Investigate oxygen’s physical properties and follow the history of its discovery, as well as its more breathtaking applications.
