Scientists observed and reported how vortex rings, swirling donut-shaped masses, move through water and reach air without ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex ...

Furthermore, research into vortex-ring collisions with density interfaces has clarified the role of buoyancy and baroclinic vorticity generation in altering the translational speed and rotational ...

Volcanic vortex rings emerge from a new pit crater on the north side of the southeast crater of the Etna Volcano in Sicily, Italy, Friday, 5 April 2024. - AP Photo/Giuseppe Di Stefano ...

VOLCANO VORTEX RINGS: Rare volcanic vortex rings were spotted rising above Mount Etna in Italy recently. The natural phenomenon occurs when gases emitted from the volcano ascend rapidly through ...

Imaging quantized vortex rings in superfluid helium to evaluate quantum dissipation. Nature Communications, 2023; 14 (1) DOI: 10.1038/s41467-023-38787-w ...

You might also spot something more ethereal: a smoke ring rising into the sky. Known as volcanic vortex rings, these floating hoops are actually made of water vapor, carbon dioxide, and sulfur ...

These “smoke rings," which are called volcanic vortex rings by scientists, are made up of gas and water vapor shot from a newly formed crater, writes the Washington Post’s Leo Sands.

Topological monopoles are a quantum physics phenomenon that can decay into what’s known as “Alice rings.” Named after Lewis Carroll’s famous heroine, this vortex ring flips the magnetic ...

The “volcanic vortex rings” come from a combination of rapid gas release and the vent shape of the new crater. SWNS “Even if a volcano has the capability to create smoke rings, strong winds ...

By the time it passed through them all to reach a detector, it was shaped like a chain of vortex rings. Yao and her colleagues called this a “spatiotemporal vortex string” and the largest they ...
