“This is a view of a ~2,000-km-wide vortex of swirling clouds above Saturn's north pole, imaged in polarized light with Cassini's narrow-angle camera on November 27, 2012. I've processed the original monochrome image to approximate the color of the area at the time.” — Jason Major
A dust storm in Olympia Planum's north polar dune fields was triggered by a late Martian summer cold front. As the northern polar cap shrinks fast, it releases cold air that sometimes moves south, like on Earth. These cold fronts strengthen in late summer and early fall due to temperature differences. Occasionally, they cause big dust storms covering large areas or the whole planet. A similar event happened a month later, leading to a global dust storm lasting most of 2018. The image, taken on April 3, 2018, by the Mars Express HRSC camera during orbit, shows natural colors. [ see full image by Aster Cowart ]
This is not natural light, nothing is from Webb. The infrared image combines data from two filters which are shown in blue and orange,. The planet displays a blue hue in the resulting representative-color image which is similar to the planet’s actual color. But in reality Uranus is more a pale blue/green. This is only the third facility to ever image the rings of Uranus: Voyager 2 spacecraft in 1986; and the Keck Observatory with advanced adaptive optics.
So this is “false color” becuase it is infrared (like all Webb images) and made from only two filters orange and cyan. However, the detail is incredible. That dot is tiny Amalthea at the left and— yes… that is Jupiter’s elusive ring. According to researcher Thierry Fouchet, “This one image sums up the science of our Jupiter system program, which studies the dynamics and chemistry of Jupiter itself, its rings, and its satellite system,”.

I’m an Australian father of four, living in the US. Something of a corner case. Nevertheless, getting my kids Australian citizenship by descent, and then Australian passports so we can fly home legally, has kicked off a carnival of errors with a very dark side. Australia is generally thought of as a developed western liberal country with relatively high state capacity. And I have generally found that at least state government services, now administered through centralized offices, have become more efficient over time. Passport applications for children living overseas, however, remain a time machine with a difficult security overhang. Australian …
Researchers created a dataset of photos of thousands of paper-thin slices of a male and female cadaver to create one of the most detailed datasets about the human body.
In a remote corner of the driest state in the country, Anne Heggli's team has been keeping watch over some of Earth’s oldest beings. Since 02012, Heggli’s NevCAN network has recorded conditions at the Nevada Bristlecone Preserve every eight minutes. The result is more than 120 million data points and a high-resolution portrait of how a bristlecone pine thrives. Paleoclimatologist Adam Csank showed how bristlecone microcores reveal the droughts and floods these trees survived long before us, a history that fine-tunes models of what's ahead. Artist and philosopher Jonathon Keats went further. “The most accurate clock,” he said, “is a tree.” His monumental artwork Centuries of the Bristlecone keeps bristlecone time, a clock calibrated to the trees' own growth over millennia. Together, Heggli, Keats and Csank made the case for long science: patient, continuous observation that will help us answer future urgent questions. “Data at this resolution,” Csank said, “is like a Rosetta Stone” for understanding nature’s resilience. At fourteen years young, the bristlecone record is just beginning, Heggli said, but it already holds the key to questions like these: How will bristlecones adapt? What happens when the droughts and floods they've weathered for millennia arrive faster and more frequently? “We can't answer the questions if we're not watching,” said Csank. “We are the stewards of this data,” Heggli concluded. “This is why we need long science.”
