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.

Behold beryllium, an exceptionally light, strong metal that is both prized and poisonous. Found in minerals such as emeralds and other forms of beryl, beryllium is highly conductive to heat and electricity, nonmagnetic, capable of great elasticity, and impervious to a wide range of temperatures, making it a favored material for aerospace projects such as space shuttles and satellites. In this video you will discover the element’s ancient and atomic histories with host Ron Hipschman!

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.

Cities are known to produce a lot of light pollution, making it a challenge for astronomy enthusiasts to view the heavens within city limits. For us in the SF Bay Area, these issues apply, however, exciting results can still be attained between sky gazing and learning about how we all fit into this big thing we call "space". Urban Astronomer Paul Salazar, The Exploratorium's very own Adam Esposito and more demonstrate how to deal with the parameters and the unforgettable experiences that await with simple to no equipment, the right conditions, and some decent timing.

With a roll of thin plastic diffraction grating and some "stolen" sunlight, artist and exhibit developer Pete Stephens transformed the interior of the Palace of Fine Arts into a dazzling riot of spectral color. As he works to recreate the effect at the new Exploratorium at Pier 15, Stephens recounts the challenges—and the inspiration—of this expansive experiment in light.

Exploratorium composer Wayne Grim used the video of the transit to create a sound composition in real time. As the video signal was received by Wayne's computer, a program he wrote converted the signal into a unique aural experience. http://www.waynegrim.com

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!
