Image: Venus Express snaps swirling vortex
This ghostly puff of smoke is actually a mass of swirling gas and cloud at Venus' south pole, as seen by the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) aboard ESA's Venus Express spacecraft.
Ready to shiver? Arctic air to put America on ice
Much of America is about to get the Arctic shivers.
Vortex of electrons provides unprecedented information on magnetic quantum states in solids
Electron states in solids are responsible for many material properties, such as color and electrical conductivity. However, because of their confinement within the crystal, it is very difficult to study the ...
Feds: Don't expect winter to be polar vortex redux
(AP)—Federal forecasters don't expect a return of frequent cold blasts from the polar vortex this winter. Nor should the weather system that blocked rain from California last winter come back.
Structured light make circular holes distinguish between left and right
(Phys.org) —A group of researchers at Macquarie University has shown that circular dichroism – a differential absorption of the circular polarization light – can be induced in mirror symmetric samples ...
Study links polar vortex chills to melting sea ice
A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of cold air as the world gets warmer.
NASA image: Saturn's vortex and rings
The Cassini spacecraft captures three magnificent sights at once: Saturn's north polar vortex and hexagon along with its expansive rings.
Researchers explain emergence of bacterial vortex
When a bunch of B. subtilis bacteria are confined within a droplet of water, a very strange thing happens. The chaotic motion of all those individual swimmers spontaneously organizes into a swirling vortex ...
Harnessing magnetic vortices for making nanoscale antennas
(Phys.org) —Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating ...
Researchers see Kelvin wave on quantum 'tornado' for first time
A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract—a process ...
Image: Churning atmosphere on Saturn
Like a swirl from a paintbrush being dipped in water, this image from the Cassini orbiter shows the progress of a massive storm on Saturn. The storm first developed in December 2010, and this mosaic captures ...
Solving a physics mystery: Those 'solitons' are really vortex rings
(Phys.org) —The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying ...
Image: Polar vortex enters northern US
The polar vortex is a whirling and persistent large area of low pressure, found typically over both North and South poles. The northern polar vortex was pushing southward over western Wisconsin and eastern ...
Weakened 'polar vortex' blamed for N. American chill
The bitter chill gripping North America is a result of Arctic air that has spilled southwards, and global warming may be a cause, an expert said on Monday.
