What's the Redoubt Volcano up to lately?

No major eruptions lately. The Volcano is currently building a lava dome.

SETI: The New Search for ET


QUEST on KQED Public Media.

" 'Is anyone out there?' For over 40 years scientists have been searching for extraterrestrial intelligence, but they’ve found nothing. Now the new Allen Telescope Array, a string of 350 radio telescopes, is being built 300 miles north of San Francisco and is breathing new life into the search. Find out why SETI scientists now say we might be hearing from ET sooner than you think."

I have often had an ET Day. Show whatever good video you have. Have your students write the pros and cons for the question, "Are We Alone?"

I like this video because it's short (11 min.) and covers the subject from a scientific--not a Hollywood--point of view, which is important, I think.
