Turbulence in Saturn’s atmosphere

21.10.2004


Turbulence in the atmosphere of Saturn


This turbulent boundary between two latitudinal bands in Saturn’s atmosphere curls repeatedly along its edge in this NASA/ESA/ASI Cassini-Huygens image.

This pattern is an example of a ’Kelvin-Helmholtz instability’, which occurs when two fluids of different density flow past each other at different speeds. This type of phenomenon should be fairly common on the gas-giant planets given their alternating jets and the different temperatures in their belts and zones.

The image was taken with the Cassini-Huygens spacecraft narrow-angle camera on 9 October 2004, at a distance of 5.9 million kilometres from Saturn through a filter sensitive to wavelengths of infrared light centred at 889 nanometres. The image scale is 69 kilometres per pixel.



The Cassini-Huygens mission is a co-operative project of NASA, ESA and ASI, the Italian space agency.

Im Focus: Regensburg physicists watch electron transfer in a single molecule

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...

Im Focus: University of Konstanz gains new insights into the recent development of the human immune system

Scientists at the University of Konstanz identify fierce competition between the human immune system and bacterial pathogens

Cell biologists from the University of Konstanz shed light on a recent evolutionary process in the human immune system and publish their findings in the...

Im Focus: Transformation through Light

Laser physicists have taken snapshots of carbon molecules C₆₀ showing how they transform in intense infrared light

When carbon molecules C₆₀ are exposed to an intense infrared light, they change their ball-like structure to a more elongated version. This has now been...

Im Focus: Famous “sandpile model” shown to move like a traveling sand dune

Researchers at IST Austria find new property of important physical model. Results published in PNAS

The so-called Abelian sandpile model has been studied by scientists for more than 30 years to better understand a physical phenomenon called self-organized...

Im Focus: Cryo-force spectroscopy reveals the mechanical properties of DNA components

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.

DNA is not only a popular research topic because it contains the blueprint for life – it can also be used to produce tiny components for technical applications.
