Quinta das Alagoas participated in the VII edition of the Birdwatching and Nature Activities Festival

Which is the color of the Sun? Why is the sky blue? Why the sunsets are red? Why the clouds are white? How is a rainbow formed? What is the sky polarization? How do birds use the Sun, the sky polarization, the stars and the magnetic field as a compass?

Quinta das Alagoas invited the participants to do some experiments and listen to some answers.

This activity ends with a safe solar observation* by projection and through a solar telescope:

Photosphere and sunspots (viewed in visible light, by projection)
Cromosphere, filaments and prominences (viewed in Hydrogen alpha emissions band in a solar telescope)
