    You're looking at a newly released 8-frame movie of Saturn's enigmatic "hexagon." It is the highest-resolution footage ever acquired of the massive six-sided maelstrom atop the ringed planet's north pole, and boy howdy is it gorgeous. For the uninitiated, Saturn's uncannily symmetric cloud system measures roughly 20,000-miles across, and is utterly unique in our solar system. Its dimensions and dynamics are just bizarre. At the hexagon's center whirls a tightly wound hurricane roughly fifty-times larger than the average hurricane-eye on Earth. About it spins an assortment of smaller vortices, caught up in the hexagon's jet stream, that rotate clockwise, even...

    This colorful view from NASA's Cassini mission is the highest-resolution view of the unique six-sided jet stream at Saturn's north pole known as "the hexagon." This movie, made from images obtained by Cassini's imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.

    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...

    A NASA probe has captured an amazing video of the huge and mysterious six-sided vortex spinning around Saturn's north pole. Scientists created the new video of Saturn's vortex from 128 images snapped by NASA's Cassini spacecraft in December 2012. It's the highest-resolution movie yet obtained of the giant hexagon, which is about 20,000 miles (32,000 kilometers) wide and has been swirling for at least 30 years, researchers said. "The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable," Andrew Ingersoll, a Cassini imaging team member at the...

    Explanation: Why would clouds form a hexagon on Saturn? Nobody is sure. Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System. If Saturn's South Pole wasn't strange enough with its rotating vortex, Saturn's North Pole might be considered even stranger. The bizarre cloud pattern is shown above in great detail by a recent image taken by the Saturn-orbiting Cassini spacecraft. This and similar images show the stability of the hexagon even 20+ years after Voyager. Movies of Saturn's North Pole show the cloud structure maintaining...

    Yesterday's post on new Cassini'S close-ups of Saturn's mysterious North Pole Hexagon were absolutely breathtaking in the view of the astounding spectacle that nature is capable of. Most of the images involving spectacles such as the Hexagon will usually be skewed to a certain color to dramatize the images to a heightened state of existence. But the images shown here today, on their merit, equally as dramatic but with a truer representation off their color persona that naturally tends to be more staid, neutral, certainly less dramatic as provided by the most recent batch of images provided below.

    One of the most bizarre weather patterns known has been photographed at Saturn, where astronomers have spotted a huge, six-sided feature circling the north pole. Rather than the normally sinuous cloud structures seen on all planets that have atmospheres, this thing is a hexagon. The honeycomb-like feature has been seen before. NASA's Voyager 1 and 2 spacecraft imaged it more than two decades ago. Now, having spotted it with the Cassini spacecraft, scientists conclude it is a long-lasting oddity. "This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides," said Kevin Baines,...

    Saturn boasts one of the solar system's most geometrical features: a giant hexagon encircling its north pole. Though not as famous as Jupiter’s Great Red Spot, Saturn's Hexagon is equally mysterious. Now researchers have recreated this formation in the lab using little more than water and a spinning table—an important first step, experts say, in finally deciphering this cosmic mystery. Saturn’s striped appearance comes from jet streams that fly east to west through its atmosphere at different latitudes. Most jets form circular bands, but the Voyager spacecraft snapped pictures of an enormous hexagonally shaped one (each side rivals Earth's diameter)...

    A mysterious giant hexagon lies above Saturn's north pole, captured by cameras on Nasa's Cassini Orbiter. Spanning 25,000km - equivalent to the width of two planet Earths - the bizarre geometric feature appears to remain virtually still in the atmosphere as clouds swirl around it. The infra-red images show the hexagon - which contains a smaller six-sided formation - extends about 60km down into the clouds. The hexagon is similar to Earth's polar vortex, which has winds blowing in a circular pattern around the polar region. On Saturn, the vortex has a hexagonal shape. The six-sided shape is in stark...

    This image shows newly discovered "hot spot" on Saturn's north pole and the mysterious hexagon that encircles the pole. Image credit: NASA/JPL/GSFC/Oxford University Despite more than a decade of winter darkness, Saturn's north pole is home to an unexpected hot spot remarkably similar to one at the planet's sunny south pole. The source of its heat is a mystery. Now, the first detailed views of the gas giant's high latitudes from the Cassini spacecraft reveal a matched set of hot cyclonic vortices, one at each pole. While scientists already knew about the hot spot at Saturn's south pole from...

    The amazing story of how our supersecret, Cold-War spy satellites took photos of the Soviet empire and dropped them to Earth, all without the help of computers, bandwidth, or digital cameras. Here's your mission, should you choose to accept it: build a camera that can take high-resolution photographs of the Earth from orbit and return them to the Central Intelligence Agency. There's only one catch: you don't get to use a computer or a single kilobyte of network bandwidth. That's the task that the United States government gave to a group of engineers at the optical instruments company Perkin-Elmer...

    This undated image made available by the National Reconnaissance Office is a declassified image of a man standing next to a satellite control section from the Hexagon program. DANBURY, Conn. – For more than a decade they toiled in the strange, boxy-looking building on the hill above the municipal airport, the building with no windows (except in the cafeteria), the building filled with secrets. They wore protective white jumpsuits, and had to walk through air-shower chambers before entering the sanitized "cleanroom" where the equipment was stored. They spoke in code. Few knew the true identity of "the customer" they met...
