The space agency says that a black-and-white version of the psychedelic GIF will help scientists learn more about wind speeds and the mini-storms inside the jet stream.
A psychedelic GIF, created by NASA with the help of images obtained by the space agency’s Cassini spacecraft, details Saturn’s six-sided jet stream around the planet’s north pole. This rare six-sided jet stream is known as the hexagon.
This psychedelic GIF is a one-of-its-kind creation, the space agency reports. Not only does it use color filters, but it’s also the first hexagon GIF to show a complete view of the top of the ringed planet down to about 70 degrees latitude. More than 20,000 miles in diameter, the hexagon is a basically a wavy jet stream of 200-mile-per-hour winds with a large, rotating storm positioned at its center.
“The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable,” posited Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology, in a news release. “A hurricane on Earth typically lasts a week, but this has been here for decades — and who knows — maybe centuries.”
Why exactly is the hexagon so stable? Scientists think that the hexagon lacks instability because Saturn lacks solid landforms. On Earth, weather patterns are disrupted when they run into landforms or ice caps.
According to NASA, Cassini snapped stunning photos of Saturn’s hexagon over a 10-hour period using a high-res camera. These images provide scientists with a window in to the motion of cloud structures within.
Scientists looked at these photos in false color, a rendering method that makes it easier to identify differences among the types of particles that exist in the atmosphere both inside and outside the unusual hexagon.
“As we approach Saturn’s summer solstice in 2017, lighting conditions over its north pole will improve, and we are excited to track the changes that occur both inside and outside the hexagon boundary,” noted Scott Edgington, Cassini deputy project scientist at NASA’s Jet Propulsion Laboratory.
