A study on brine shrimp just taught us something new about the mysterious rules of turbulence. The work may have applications in areas such as pollution control and drug design.https://www.quantamagazine.org/sea-monkeys-show-scientists-how-to-rewrite-a-rule-of-turbulence-20261002/

Scientists assumed that energy flows in only one direction in a turbulent system. What they didn't know, until they looked closely at brine shrimp, was that a simple factor can reverse the flow.

#NASAWebb has provided a crash course on planet-shattering collisions, providing clues to the amount of energy in their collisions. (1/6) 🧵 🔭 🧪
Artist’s concept of a star and its debris disk against the black background of space. The star is in the background, right of center, and depicted as a small, luminous sphere. The debris disk is a large blue ring that encircles the star. The debris disk is angled toward the viewer, so that the portion nearest to the viewer extends beyond the bottom frame of the illustration. Many dark, rocky fragments are scattered throughout the debris disk. In the foreground, toward the left, is a small planetary embryo colliding into the left side of a larger spherical object. The impact site glows bright yellow and orange and has a mottled appearance, as though chunks of both colliding bodies are breaking up and being destroyed. Orange-yellow streams of vapor extend outward from the collision area. Behind the debris disk and its star are many small stars in the background. A label in the bottom right corner reads “Artist’s Concept.”

Astronomers theorize that the black hole at the center of Centaurus A influences the region as it feeds and launches powerful outflows. Learn more about the impact of its central black hole with a printable poster of this observation from #NASAWebb: go.nasa.gov/4hwsDlf
A horizontally oriented poster with an image of Centaurus A against a black background. The galaxy is brightest at its center, where a brilliant white and pink glow radiates outward. Wispy, ‘S’-shaped ribbons of pink arc above and below the center of the image. A parallelogram-shaped band of gray and white dust cuts across the middle of the galaxy. The galaxy’s outer edges fade into soft textures that stretch toward the left and right sides of the image. Along the bottom is a series of thin vertical bars ranging from purple at left to blue, green, yellow, orange, and red at right. Bars are separated slightly, with black in between. Bar colors are brightest at the bottom, fading up to black. Brightness varies from bar to bar, giving the array an undulating feel. At upper right is text that reads, “National Aeronautics and Space Administration” and NASA’s blue, white, and red meatball insignia. Title text appears at lower left that says, “James Webb Space Telescope: Centaurus A.”

This starry view of the nearby star-forming region IC 348 sits just 1,000 light-years away in the constellation Perseus. Cold clouds of molecular hydrogen gas collapse to form new stars, creating glowing, sculpted scenes like this one. (1/5) 🧵 🔭
A star-forming region. The left two thirds is blanketed in thick clouds of green and yellow gas and dust that form swirling patterns. Some of the gas is spread into thin, thread-like wisps. The right third shows a black background speckled with stars and multi-colored dots that are distant galaxies. Bright stars are scattered throughout the clouds, with the densest cluster situated in the center. Each is crowned with six long spikes and two shorter spikes created by the optics of the telescope’s mirrors. In the upper right, a couple of hidden stars blast out long, glowing jets of material that glow in blue.
