Join the Origins team as they travel to Antarctica. We sent Mary, Noel, Paul, and Julie to explore scientific wonders from McMurdo to the Pole. Learn all about the extreme science being conducted at the South Pole in a daily dispatch from Terra Australis Incognita! Today from the South Pole, Mary Miller speaks to Kathryn Rollins, who will tell us about the AMANDA Neutrino Dectector. Dr. Nils Halvorson is in the Live@ studio and sheds light on the DASI telescope at the South Pole. On Thursday, June 21, 2001, a total solar eclipse sped across the Southern Hemisphere. The shadow of the moon first darkened the South Atlantic about 250 miles east of the Uruguay coast. It crossed the Atlantic Ocean, traversed southern Africa and the island of Madagascar, and then vanished into the darkness as night fell over the Indian Ocean. We sent our crew to the country of Zambia to bring images of the total solar eclipse as it happened. The first-ever live event inside the NASA clean room, where space hardware is being prepared for the Hubble Space Telescope. We'll get dressed in "bunny suits" to explore the room and show you the activities of engineers and scientists getting ready for the next Hubble servicing mission in November. A unique chance to watch the live progression of the making of a Hubble image! We'll select an image to follow over the course of the following webcasts, showing you the steps along the way as it goes from raw data to a full-color picture. And we'll talk with people who bring Hubble's fantastic images to the public. Part 2 of the previous program. Hubble's pictures have changed our understanding of the galaxy. Here we meet scientists who show us how their images have led to new discoveries, then check in on our own imaging project and track its progress. How much time does an astronomer need to get that great picture? We'll talk with scientists about how they determine their experiments, and learn what it takes to make their case for a few minutes of the telescope's time. On November 15th, 1999, for the first time in 25 years, the planet Mercury passed between us (in the western hemisphere) and the sun--an event known as a "transit." Here is one of five short streaming videos detailing the event.
