That last photo shows thermal infrared images of Saturn, taken this January, during a rare storm. It's from this fascinating article about Saturn's weather from Science Daily. Saturn apparently gets these massive storms once every year (which is every 30 Earth years) so this is the first time scientists have been able to capture one with our modern technology. It's also the first time images of the storm were ever captured from an orbiting spacecraft. It's amazing to think how far we've come in the 30 years since Saturn's last storm, isn't it?!
Also, I adore this video from NPR about the mystery of why we can't walk in a straight line. I never even knew this.. now I wish I had some giant fields nearby to test it out!
