Nicole SharpA Stellar Look at NGC 602The young star cluster NGC 602 sits some 200,000 light years away in the Small Magellanic Cloud. Seen here in near- and mid-infrared, the cluster is a glowing cradle of star forming conditions similar to the early universe. A large nebula, made up of multicolored dust and gas, surrounds the star cluster. Its dusty finger-like pillars could be an example of Rayleigh-Taylor instabilities or plumes shaped by energetic stellar jets.

Nicole SharpStrandbeest Evolution <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/sbeest1.png" rel="nofollow noopener noreferrer" target="_blank"></a> <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/sbeest2.png" rel="nofollow noopener noreferrer" target="_blank"></a> <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/sbeest3.png" rel="nofollow noopener noreferrer" target="_blank"></a> Theo Jansen’s Strandbeests are massive, wind-powered kinetic sculptures designed to roam Dutch beaches. Conceived in the late 1980s as a way to kick up sand that would replenish nearby dunes, the beests have grown into a decades-long obsession for the artist and his followers. This Veritasium video charts the development and evolution of the Strandbeest from its original concept through Jansen’s increasingly self-sufficient versions. I found the leg linkage of the Strandbeest especially fascinating. How neat to find a relatively simply proportion of linkages capable of turning a small crank’s motion into a stable walking gait. Anyone else feel like building a miniature Strandbeest now?

Nicole Sharp“My Own Galaxy”Fungal spores sketch out minute air currents in this shortlisted photograph by Avilash Ghosh. The moth atop a mushroom appears to admire the celestial view. In the largely still air near the forest floor, mushrooms use evaporation and buoyancy to generate air flows capable of lifting their spores high enough to catch a stray breeze.

Nicole Sharp“Waterfall Wonder”The Semeru volcano rises in the background of this photo of Java’s Tumpak Sewa waterfall by Joan de la Malla. Rain that falls on the volcano slides down its flank and wanders through the jungle on its way to the spectacular 120-meter-high waterfall. From the clouds wreathing the mountain through the jungle’s drifting fogs to the mists of the falls, this portrait highlights the many forms water takes on its journey.

Nicole SharpBubbling UpBy volume, Lake Baikal is the world’s largest lake, holding over 20% of the planet’s fresh water. It’s also a major carbon sink, holding large amounts of methane. That’s the gas trapped in the frozen bubbles seen here. Baikal’s ice is exceptionally clear, making long trails of frozen bubbles visible during the winter.

Nicole Sharp“Flowing Kelp”This CUPOTY-shortlisted photo by Sigfrido Zimmerman shows <a href="https://en.wikipedia.org/wiki/Macrocystis" rel="nofollow noopener noreferrer" target="_blank">giant kelp</a> drifting in the current. At the base of each blade is an inflated bladder that helps keep the algae buoyant. The blades themselves are furrowed on their surface, with patterns reminiscent of sand ripples. Though giant kelp can grow to as large as 60 meters, the species lives in constant flux, pushed and pulled by the currents that run along its length. (Image credit: S.

Nicole Sharp“Magic of the North”Fires glow above and below in this award-winning image from photographer Josh Beames. In the foreground, lava from an Icelandic eruption spurts into the air and seeps across the landscape as it slowly cools. Above, the northern aurora ripples through the night sky, marking the dance of high-energy particles streaming into our atmosphere, guided by the lines of our magnetic field. Throw in some billowing turbulent smoke, and it’s hard to get more fluid dynamical (or beautiful!) than this.

Nicole SharpSoaring Through the Pillars of CreationThe Pillars of Creation are an iconic feature nestled within the Eagle Nebula. For decades, the public has admired Hubble’s images of this stellar nursery, and, in this video, we get to fly between the pillars, shifting between Hubble’s visible light imagery and JWST’s infrared views. In visible light, glowing dust obscures the interior of the pillars, drawing our eyes instead to the dusty shapes eroded by the stellar winds of these young stars. In infrared wavelengths, we see further into the pillars, revealing individual stars burning at the ends of the pillars’ fingers. Being able to peer at the same problem through different techniques — here visible and infrared light — reveals more to scientists than either mode can on its own.

Nicole SharpA Mini JupiterAstronaut Don Pettit <a href="https://x.com/astro_Pettit/status/1847989625807065337" rel="nofollow noopener noreferrer" target="_blank">posted</a> this image of a Jupiter-like water globe he created on the International Space Station. In microgravity, surface tension reigns as the water’s supreme force, pulling the mixture of water and food coloring into a perfect sphere. It will be interesting to see a video version of this experiment, so that we can tell what tools Pettit used to swirl the droplet into the eddies we see. Is the full droplet rotating (as a planet would), or are we just seeing the remains of a wire passed through the drop? We’ll have to stay tuned to Pettit’s experiments to find out.

As water continues evaporating, the residues warp, bend, and crack. In this video, researchers set their science to the music of Leonard Cohen. The results resemble blooming flowers and flying water fowl. If you’d like to learn more about the science behind the art, check out the two open-access papers linked below.

Nicole SharpIce Without Gravity<a href="https://arstechnica.com/space/2024/10/nasa-astronaut-don-pettit-is-a-giant-nerd-and-were-all-luckier-for-it/?__readwiseLocation=" rel="nofollow noopener noreferrer" target="_blank">Astronaut Don Pettit</a> is back in space, and that means lots of awesome microgravity experiments. Here, he grew thin wafers of ice in microgravity in a -95 degree Celsius freezer. Then he took the ice wafers and photographed them between crossed polarizers, creating this colorful image. The colors highlight different crystal orientations within the ice and give us a hint about how the freezing front formed and expanded. I can’t wait to see more examples!

Santiago Andrés TrianaThe obstacle is a pencil, stationary, while the lazy Susan spins underneath with the fluid. The <a href="https://fediscience.org/tags/rheoscopic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rheoscopic</a> fluid (easily made at home, more on that on another post) allows the currents to be seen easily. An instability makes the fluid "oscillate" and create the von Kármán vortices as it flows around the pencil.
