What motivates modern navigators? That depends on who you ask. But many explain their passion for voyaging in terms of kuleana--responsibility.

The intertwining of astronomy, Hawaiian ancestry, and traditional navigation are the subject of this video featuring astrophysicist Paul Coleman, cultural historian Koa Rice, and captain Billy Richards.

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.

While in the field, the Exploratorium Eclipse remote team had a love/hate relationship with the clouds. The cloudscape of the Weizi Gorge was so spectacular it was easy to overlook that our fluffy friends could have potentially blocked our main reason for lugging 1700 lbs. of gear out to the edge of the Gobi Desert-the total solar eclipse! This is a short time-lapse video of the sky at our camp one day before the eclipse.

Ken Murphy, creator of A History of the Sky— a time-lapse visualization that will span an entire year—talks about his project during the After Dark event, Resolution.

Which is farthest away from the earth, the stars or Pluto? The answer may be obvious to you, but a lot of people get this wrong. Listen to TI director Linda Shore as she presents a little survey about how things are arranged in the heavens—and explains what the surprising results mean.

Is water ice present or absent in a crater near the moon's south pole? NASA’s Lunar CRater Observing and Sensing Satellite (LCROSS) mission is seeking a definitive answer. Join Exploratorium staff for a special Webcast featuring live coverage of LCROSS crashing into the moon! Our team will be broadcasting live from the 36" Refractor Telescope at Lick Observatory on Mt. Hamilton, where we’ll watch the impact and investigate how this intentional crash could reveal the existence of water ice.

Dr. Laura Peticolas is a physicist at UC Berkeley's Space Physics Research group. She studies the Aurora to learn more about the Earth and the workings of our Solar System. She's currently working with NASA's Mars data to understand why the Martian aurora looks the way it does. In this podcast she discusses her research, her inspiration and how and why scientists sonify data.

Astrophysicist and native Hawaiian Dr. Paul Coleman is used to operating in the worlds of both science and spiritual tradition. But in this short podcast, he tells a story of one time when those two worlds clashed, and he was reminded of the importance of remembering his native roots.

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.
