Astra's Stargate (a cool website by NASA astronomer Dawn Jenkins)

This site is packed with interesting information about astronomy, space exploration, women in astronomy and science, and Maya astronomy. I strongly recommend to visit Dawn's page

Taller de Astronomía Rayuela (near Madrid, Spain)

Here is a link to the blog of an amazing group of high school students and their teacher, Julio Camarillo, a class that began to study astronomy and have expanded to include astronautics and astrophysics. Visit this blog and watch the exciting videos and other material the smart group has produced in just a few months. http://tallerastronomia07.blogspot.com/
