New Characterization of the Mesospheric Polar Vortices
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.
High-Altitude “Wind Walls” Discovered near Magnetic Poles
Satellite imaging reveals two narrow channels of extreme winds surrounded by gentle opposing flow 140–250 kilometers above sea level.
Evidence of Regional Deposition in Mars’s South Polar Deposits
Shallow Radar correlation of discrete units in one of the Red Planet’s largest ice reservoirs suggests that its material was emplaced as a single, regional deposit.
Juno Gets Spectacular View of Jupiter’s Aurora
The NASA spacecraft has taken images of Jupiter’s powerful aurora dancing around its poles, revealing never-before-seen details in their structure.
Time, Tides, and Wandering Poles
Models of Neptune’s moon Triton reveal curious behavior in how tidal forces and mass anomalies cause the poles to reorient their location.
Mysterious Particle Beams Found over Jupiter’s Poles
The unexpected character of the beams, revealed by NASA’s Juno spacecraft, suggests that the processes that produce Jupiter’s auroras are unlike those on Earth.
Mars Polar Intrigue Spurs Multidisciplinary Collaboration
Sixth International Conference on Mars Polar Science and Exploration; Reykjavík, Iceland; 5–9 September 2016
Polar Interlopers in the Aurora
A new study suggests that poleward boundary intensifications in the aurora are caused by fast flows of plasma from the poles into the auroral oval.
How Mars Got Its Layered North Polar Cap
Orbital wobbling shaped the dome of ice and dust at the planet's north pole.
