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.

Robots have gone where no one has gone before and sent back photographs of things never before seen. Witness robot-captured photos of hellaciously hot venus, cryogenically cold Titan, and many places in between. Join Exploratorium Senior Scientist Paul Doherty to a brief exploration of the images that have captured our imaginations.

As cameras became more sophisticated, so too did our understanding of projective geometry. In this brief talk, we’ll explore how the art of photography has helped reveal the elegant mathematics of vision.

5 years and 5 servicing missions have provided scientists and the public with unprecedented views of our universe. From objects as close as our solar system to the furthest reaches of the Universe, we’ll look at some of these images and discuss what it took to get them.

The legendary Joshua Light Show returns to the Exploratorium’s Kanbar Forum to improvise an immersive, otherworldly environment of light in collaboration with acclaimed musicians Julia Holter and Linda Perhacs.

Join Dr. Jay Daniel, Director of Engineering at L-3 Integrated Optical Systems Tinsley, to explore beryllium’s central role in the future James Webb Space Telescope.

Join us for a live webcast with senior scientist Paul Doherty to discuss breaking news about the Rosetta Mission! The European Space Agency’s Rosetta mission deployed its lander, Philae, to the surface of Comet 67P/Churyumov–Gerasimenko on November 12. 2014. Philae’s landing site, currently known as Site J, is located on the smaller of the comet’s two ‘lobes’, with a backup site on the larger lobe. The sites were selected just six weeks after Rosetta arrived at the comet on August 6, following its 10-year journey through the Solar System.

The race to find Philae's landing site could only begin once Rosetta arrived at comet, 67P/Churyumov–Gerasimenko on August 6th, when the comet was seen close-up for the first time. Since then, the spacecraft has moved to within 30 km of the comet, affording more detailed scientific measurements of the candidate sites. In parallel, the operations and flight dynamics teams have been exploring options for delivering the lander to all five candidate landing sites. Join Exploratorium Senior Scientist, Isabel Hawkins for a live webcast detailing the amazing stages of the Rosetta Mission!

Join us as Rosetta moves ever closer to Comet 67P/Churyumov-Gerasimenko’s nucleus to map potential sites for a November landing.

The most difficult phase of the Rosetta mission is the final rendezvous with the fast-moving comet. Learn what steps the ESA scientists and engineers are taking to ensure a successful landing for November 2014.
