Southern Jupiter from Perijove 3
Southern Jupiter looms some 37,000 kilometers away in this JunoCam image from December 11. The image data was captured near Juno's third perijove or closest approach to Jupiter, the spacecraft still in its 53 day long looping orbit. With the south polar region on the left, the large whitish oval toward the right is massive, counterclockwise rotating storm system. Smaller than the more famous Great Red Spot, the oval storm is only about half the diameter of planet Earth, one of a string of white ovals currently in the southern hemisphere of the Solar System's, ruling gas giant.

“The secret of mountain climbing is to walk slowly, so that you will not tire, and to put down your feet on level spots, so that you will not stumble. This one should know.” The quote is written in calligraphy by an important government official and poet during the Qing Dynasty, Qian Feng (1740-1795) who is remembered for his courage in speaking out against corruption in high places. On this scroll, Qian Feng recorded words which Sima Guang (1019-1086 CE), a Song-dynasty historian and conservative politician, had inscribed at the top of a mountain.
Sir Francis Bacon: Preserver of Chickens
In 1626, Sir Francis Bacon, one of the most influential minds of his time, was watching a snowstorm. He was struck by the notion that maybe snow could be used to preserve meat. And he wasn’t exactly wrong: people everywhere put chickens in their freezers to preserve them. Sadly for him Bacon was a man too far ahead of his time. In 1626, electricity hadn’t even been invented let alone artificial cooling. But did that stop Bacon? Of course not.
Determined to find out if snow could preserve meat, he purchased a chicken from a nearby village, killed it, and then, standing outside in the snow, tried to stuff the chicken full of snow to freeze it. The chicken never froze. But Bacon caught a cold that turned into pneumonia, and died shortly afterward.
