Cassini spacecraft obtains best views of Saturn hexagon
NASA’s Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn’s north pole.
This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude. Spanning about 20,000 miles (30,000 kilometers) across, the hexagon is a wavy jet stream of 200-mile-per-hour winds (about 322 kilometers per hour) with a massive, rotating storm at the center. There is no weather feature exactly, consistently like this anywhere else in the solar system.
"The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable," said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena. "A hurricane on Earth typically lasts a week, but this has been here for decades—and who knows—maybe centuries."…

These gorgeous 1871s illustrations for Jules Verne’s Twenty Thousand Leagues Under the Sea by artist Alphonse de Neuville are hauntingly reminiscent of Edward Gorey’s illustrations for H. G. Wells’s War of the Worlds.
Also see these stunning 1964 illustrations for the Verne biography The Man Who Invented the Future.

Looking like it just swam out of a horror movie is the amazing fangtooth. Known scientifically as Anoplogaster cornuta, this menacing creature haunts the deep waters of many of the world’s oceans. The fangtooth gets its name from its rather impressive looking teeth, which are actually the largest teeth of any fish in the ocean when taken in proportion to body size. Because of its unusually grotesque appearance, the fangtooth has earned the nickname “ogrefish”. It is also referred to by some as the common sabretooth. Undoubtedly the most noticeable characteristic of this species is the teeth. They are so large that the fangs on the lower jaw actually slide into specially formed pockets in the roof of the mouth when the jaw is closed. These pockets extend into sockets on either side of the brain. These teeth become a formidable weapon as the fangtooth hunts squid other small fish. Because its eyesight is not good, many researchers think the fangtooth hunts by a process known as chemoreception, where it essentially must bump into something edible as it searches the dark waters. It is believed that these fish migrate to upper layers of the ocean to feed during the night and then return to the murky depths during the day. If a fangtooth wanders too close to the surface, it risks becoming a meal for larger fish species such as marlin or tuna.Sources (1,2)
