Explanation: What would it look like to fly over the North Pole of Jupiter? A fictional animation made from real images and data captured by NASA’s Juno spacecraft shows an answer. Since the pole is presently in shadow, the video uses infrared light emitted by Jupiter — specifically an infrared color where the hottest features glows the brightest. As the animation starts, Juno zooms in on the enormous world. Soon, one of the eight cyclones orbiting the North Pole is featured. One by one, all eight cyclones circling the pole are inspected, each the size of an entire continent on Earth, and each containing bumpy and fragmented spiral walls. The virtual trip ends with a zoom out. Studying Jovian cyclones helps humanity to better understand dangerous storm systems that occur here on Earth. Juno has recently concluded another close pass by Jupiter — Perijove 12 — and seems healthy enough to complete several more of the two-month orbits.
Although the origins of many words are rather odd and esoteric in nature, the origins of the words “uppercase” and “lowercase” to refer to capitalized and uncapitalized letters is quite straightforward.
Back when every bit of printed material had to be handset by a printer or their assistants, the letters were arranged by frequency of use. The infrequently used capital letters went in the “uppercase”, a slanted shelf above the main work area. The frequently used uncapitalized letters went in the “lowercase”, a more accessible shelf closer to the workstation.
