Whether you want to call it a “Blood Moon”, “Harvest Moon” or a “Supermoon” ...the rare total Lunar Eclipse happening on September 27th hasn't happened in 32 years, and won't happen again for another 18 years. If you are on the west coast the eclipse will begin at 7:11 p.m. PDT Sunday evening and will last one hour and 12 minutes.

On February 26, 1998, a total solar eclipse darkened skies in a swath stretching from the Pacific Ocean to the Atlantic, across the Caribbean. From the island of Aruba, an Exploratorium team presented a live Webcast of this celestial event. At the time, Webcasting technology was in its infancy, and this first live Webcast ever of a solar eclipse broke existing records for the number of viewers. Watch the archived Webcast here, or just click on the images below for still photos of eclipse highlights.

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.

Watch the beginning of Venus’s transit across the disk of the sun, one of the rarest astronomical events.

Watch the conclusion of Venus’s 6.5-hour journey across the disk of the sun, one of the rarest astronomical events.

Senior Exploratorium Scientist, Paul Doherty demonstrates how you can make your own sun viewer. You can safely view sunspots, eclipses and transits with this equipment that you may have laying around the house!

XTech at the Exploratorium empowers high school students through the practical use of Science, Technology, Engineering, Art, and Mathematics. Students develop skills - designing and building, creating media, and facilitating community education events - that will lead them into college and beyond. In this show, we will be investigating lasers. Did you know that that LASER was an acronym? It stands for Light Amplification Stimulated by the Emission of Radiation. Join us in learning how a laser works, as well as a real world application for lasers, and finally, how they can create stunning light patterns.

This After Dark event presented a collection of objects, organizations, and activities use various alternative energy sources, and also looked at sustainably raised food.

Astronomer Dr. Isabel Hawkins's journey to the stars began with two chance moments of enchantment with celestial bodies in her native Argentina. Inspired by the mystery of the sky, she went on to study physics and astronomy in California and then to work for 20 years as a research astronomer at UC Berkeley. Now retired from research and devoted to inciting a love of the stars and sky in young people, Dr. Hawkins reflects on her own initial moments of inspiration, on sharing her love of stars with others, and on how astronomy can, and should, remind us of our connection to one another, under a canopy of mystery.

The Exploratorium Eclipse team drives back to Urumqi with our partners from XJTV, after the live broadcast. It was pretty hot, probably above 40 °C most of the way, and a 14 hour drive. This is a time-compressed video of of the trip out to the Weizi Gorge (Yiwu) along China’s cloud-covered Silk Road.
