Eliminating Uncertainty One Cloud at a Time
The impact of clouds on climate change has been a scientific mystery for decades. Now researchers are fighting to gain the upper hand.
No Evidence for Unknown Source of Ozone Precursor
A study suggests that known combustion and photochemical sources of nitrous acid, a precursor to ground-level ozone, are enough to explain levels seen in the atmosphere.
Jupiter's Auroras Recharge Between Solar Storms
New research suggests that Jupiter's magnetic field replenishes its stock of plasma during lulls in solar activity, creating spectacular displays when a solar storm hits.
Scientists Solve Charon's Red Mystery
Why are Charon's poles dusted with reddish material?
A Flip-Flopping Climate Could Explain Mars's Watery Past
A new hypothesis might reconcile two opposing theories that have tried to explain Mars's mysterious history for more than 40 years.
Mysterious Anomaly Interrupts Stratospheric Wind Pattern
For the first time, scientists have observed a deviation from the typical alternating pattern of easterly and westerly winds in the equatorial stratosphere.
Even the Magnetosphere Has Problems
In a new conference and collection of papers, international space physicists narrow down the enigmas that puzzle magnetospheric science.
Mysteries of the Magnetosphere
Scientists investigate how dipolarization fronts in Earth's protective magnetosphere interact with the environment around them.
Chasing Down the Slow Solar Wind
The Sun's plasma blasts Earth’s magnetosphere at more than a million miles per hour. The fastest pours from holes in the corona, but until recently the source of the "slow" solar wind was a mystery.
