Rain

I must admit that yesterday was one of those days when I didn’t had time to breathe. I was so busy that I couldn’t even open my blog and see what’s new or watch at least half an episode from my favorite TV shows (believe me, I always find time for my shows!). And above all, you should have seen the weather here. Oh, it was so dark and rainy I thought it was the end of the world… Continue reading Rain

Aurora: Earth’s Little Wonder

An aurora, sometimes referred to as a polar light, is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere), where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.  Continue reading Aurora: Earth’s Little Wonder
