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.

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.

Video teaser for the upcoming launch of the new Exploratorium website, 'Never Lost'. Learn a little bit about Polynesian Navigation in anticipation of the full website

Astrophysicist Paul Coleman and expert ocean navigator Kalepa Baybayan visited the Exploratorium as advisors to our Polynesian Navigation project—a large-scale Web resource (launching April 2010) that will feature the astounding navigation practices of the Pacific Islanders, who were expertly navigating the Pacific thousands of years before the arrival of Europeans. Paul Coleman works at the University of Hawaii Institute for Astronomy, where he concentrates on the large-scale structure of the universe. Kalepa Baybayan is an expert navigator who mentors Hawaiian youth in native navigation practices. Both men are native Hawaiians. We spoke with them about traditional navigation practices, the balance between science and spirituality from a native perspective, and the benefits of being grounded in one’s culture.

Why do the hands on clocks go "clockwise?" Seems like a circular definition, but if you looked closely at sundials in the northern hemisphere, you'd notice that the shadow of the sun moves around the sundial in a "clockwise" direction. This was adopted by clock-makers and became the standard we know today. In the southern hemisphere, the sun's shadow moves around the dial in the opposite direction, so if clocks had been invented there, our watches would move the other way.

An interview with Isabel Hawkins, Co-director/Research Astronomer, UC Berkeley Space Sciences Laboratory; Co-director, NASA Sun-Earth Connection Education Forum.

When astronomer Isabel Hawkins began exploring the astronomical work of Native Americans, their knowledge broadened her view of the night sky. She's since discovered several scientists incorporating the work of native people, both modern and ancient, into their current-day research. Isabel describes how she sees science as a cultural construct, the value of learning from personal experience, and that evidence comes in many forms.
