Passport to Knowledge: "Auroras - Living With a Star"

5:00-6:00 p.m. and 9:00-10:00 p.m.

Auroras -- the Northern and Southern Lights -- are still one of the most dramatic and mysterious natural phenomena. Their shapes and colors both frightened and inspired our ancestors. Now we know much about what causes them and recognize them as a sign of Earth's connection to our local star, the Sun. Their shimmering colors reveal the otherwise invisible layers of the atmosphere: they demonstrate the importance of Earth's magnetosphere to life on our planet.

AURORAS -- LIVING WITH A STAR is the first of two LIVE FROM specials from PASSPORT TO KNOWLEDGE, public television's longest-running series of interactive learning adventures. Together with LIVE FROM THE AURORA, which debuted on March 18, 2003, they form the video component of an integrated multiple media package which also includes Web sites and, hands-on activities and online opportunities

The broadcasts connect core science concepts to exciting real-world research, using unique imagery from around our planet and up in orbit, as well as advanced computer graphics. Through the programs teachers can help students explore and explain electricity and magnetism, atoms and particles, optics and the electromagnetic spectrum, the structure and dynamics of Earth's atmosphere, and sunspots and solar cycles.

Passport to Knowledge: Looking for Life

5:00-6:00 p.m. and 9:00-10:00 p.m.

Is life on Earth unique? Are humans the only intelligent beings in the universe? These are some of the deepest and most ancient of questions. Now, for the first time, we have the tools and technology to begin probing for the answers. Scientists believe these answers lie untouched in some of the most exotic and dramatic sites on our home planet. "Looking for Life" takes viewers to these distant locations for the most current reports on this exciting scientific frontier.

In the rust-red Pilbara desert of Western Australia, an international team of NASA and university researchers looks at ancient rocks to see if they offer unambiguous evidence of life on Earth as long as 3.5 billion years ago. At Shark Bay, a young graduate student dives in chilly waters to sample stromatolites, "living fossils" that may resemble early life-forms. In the startling red and yellow waters of Spain's Rio Tinto, an intrepid cameraman ventures underwater to photograph the rich organisms found in some of the most acidic streams on Earth. Nearby a NASA team tests a prototype drill that could be deployed to Mars or to Jupiterís mysterious moon, Europa. North of the Arctic Circle, researchers from Indiana University look for life deep underground in the Lupin Mine. South of the Equator, far up in the Bolivian Andes, NASA's Nathalie Cabrol dives in the highest waters on Earth, whose salty shores resemble the ancient lakes recently found on Mars by NASA's rovers, Spirit and Opportunity. She finds organisms thriving in an environment of extreme cold and dangerous levels of radiation.
