Apollo Sunrise - June 20th, 1996.

"In November of 1969, homeward bound aboard the "Yankee Clipper" command module, the Apollo 12 astronauts took this dramatic photograph of the Sun emerging from behind the Earth. From this distant perspective, part of the solar disk peers over the Earth's limb, its direct light producing the jewel-like glint, while sunlight scattered by the atmosphere creates the thin bright crescent. June 20th was the date for the 1996 summer solstice. From an earthbound perspective, the solar disk would climb to its greatest northern declination, marking the northern hemisphere's first day of summer and creating the longest day - with over 15 hours of daylight near a latitude of +40 degrees."

"Quantum 'Starry Night': Physicists capture elusive instability and exotic vortices"

"Van Gogh's "The Starry Night" has stirred the souls of art lovers for over a century. Now, its swirling skies may also speak to physicists, as it echoes the patterns of quantum turbulence.

("The swirling patterns in Vincent van Gogh's "The Starry Night" can help us visualize quantum Kelvin-Helmholtz instability (KHI). The central spiral and surrounding stars and moon resemble the vortices formed where two fluids meet. Van Gogh's iconic crescent may even hint at the crescent-shaped skyrmions seen in quantum KHI.

Physicists at Osaka Metropolitan University and the Korea Advanced Institute of Science and Technology have for the first time successfully observed the quantum Kelvin–Helmholtz instability (KHI)—a phenomenon predicted decades ago but never before seen in quantum fluids. The instability produces exotic vortex patterns known as eccentric fractional skyrmions, whose crescent-shaped structures bear a resemblance to the moon in Van Gogh's masterpiece.

KHI is a classic phenomenon in fluid dynamics, where waves and vortices form at the boundary between two fluids moving at different speeds—as seen in wind-whipped ocean waves, swirling clouds, or Van Gogh's skies.

"Our research began with a simple question: Can the Kelvin–Helmholtz instability happen in quantum fluids?" said Hiromitsu Takeuchi, an associate professor at Osaka Metropolitan University's Graduate School of Science, and one of the lead authors of this study.

By cooling lithium gases to near absolute zero, the researchers created a multi-component Bose–Einstein condensate—a quantum superfluid—with two streams flowing at different velocities. At their interface, a wavy fingering pattern emerges, mirroring classical turbulence, but then vortices are generated, governed by the strange rules of quantum mechanics and topology.

These vortices turned out to be eccentric fractional skyrmions, or EFSs—a newly discovered kind of topological defect.

"Skyrmions are usually symmetrical and centered," Takeuchi said. "But EFSs have a crescent-like shape and contain embedded singularities—points where the usual spin structure breaks down, creating sharp distortions. To me, the large crescent moon in the upper right corner of 'The Starry Night' looks exactly like an EFS," Takeuchi said.

Skyrmions, first discovered in magnetic materials, are attracting growing interest for use in spintronics and memory devices due to their stability, small size and unusual dynamics. The discovery of a new kind of skyrmion in a superfluid could have implications for both applied technologies and our understanding of quantum systems."
