The mystery behind lunar swirls, one of the solar system’s most beautiful optical anomalies, may finally be solved thanks to a joint Rutgers University and University of California Berkeley study. The solution hints at the dynamism of the moon’s ancient past as a place with volcanic activity and an internally generated magnetic field. It also challenges our picture of the moon’s existing geology.

More than 100 oceanic floats are now diving and drifting in the Southern Ocean around Antarctica during the peak of winter. These instruments are gathering data from a place and season that remains very poorly studied, despite its important role in regulating the global climate.

Two years after a research team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they’ve uncovered tantalizing clues to the waves’ origins. The interdisciplinary science team’s work to understand the formation of “persistent gravity waves” promises to help researchers better understand connections between the layers of Earth’s atmosphere—helping form a more complete understanding of air circulation around the world.

Clouds are an inspiration to most of us, but a nightmare for climate scientists. Clouds are exceptionally complex creatures, and that complexity makes it difficult to predict how and where they’ll form – which is unfortunate, since those predictions are essential to understanding precipitation patterns and how our climate will change in the future.

Scientists have discovered hundreds of crescent-shaped pits on Mars where sand dunes stood billions of years ago. The curves of these ancient dune impressions record the direction of prevailing winds on the Red Planet, providing potential clues to Mars’s past climate, and may hold evidence of ancient life.

A new study in the Journal of Geophysical Research: Atmospheres observes rare terrestrial gamma ray flashes produced by lightning strikes.

A new study finds the fires that spread throughout North America last summer burned so powerfully their smoke pushed all the way into the stratosphere, circled the globe in roughly two weeks and remained in the stratosphere at measurable levels for several months.

A new study identifies a method for predicting the likelihood of damaging hailstorms in the United States—up to three weeks in advance. Hail is the most economically destructive hazard posed by severe thunderstorms, producing on average billions of dollars in U.S. losses each year, including damage to roofs, homes and especially crops.

Global temperatures spiked during the record warm years of 2014 to 2016 largely because El Niño released an unusually large amount of heat generated by greenhouse gas emissions and stored in the Pacific Ocean, a new study finds.

Earth’s surface is constantly shifting, expanding and compressing in response to atmospheric and hydrologic forces from aboveground. A new study finds that compression of Earth’s crust is correlated with heavy rainfall from hurricanes and typhoons, known collectively as tropical cyclones. The added weight of all that water likely causes the ground underneath the storm to deform, according to the study’s authors.
