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.

Brendan Kelly learned from Inuit hunters how to train Labrador retrievers to find ringed seals. This allows Brendan and his colleagues to set up live-capture nets to keep the seals from diving after they come up for air. The seals are tagged with satellite transponders so they can be tracked to learn about their breeding grounds and migration habits.
