I know the weekend is gone and it’s Monday today, but I can’t skip the most popular section of this blog, the weekend videos. So here they are. The first video is a beautiful display of oil in water using macro lens by Jesse Zanzinger. Beautiful video and great choice of music as well. The second video is a time-lapse video of beautiful Aurora Borealis as observed in Norway during August 2010 and photographed by Tor Even Mathisen. It’s just spectacular. As described in my earlier posts (here and here), when high energetic ions ejected from sun interact with our atmosphere, they energize Oxygen and Nitrogen atoms which then emit radiations; green color is due to Oxygen. Enjoy the videos, I hope you all had a great weekend!
