Dynamics of ocean worlds likely controlled by their rotation

Discovering that many of the large moons in the outer solar system may host significant subsurface oceans of liquid water has been a key advance in planetary science. These moons represent some of the most promising habitats ...

Earth's atmosphere may be source of some lunar water

Hydrogen and oxygen ions escaping from Earth's upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical ...

Flame-retardants and plasticizers found in the oceans 

After the successful ban of the flame-retardant substances called PBDEs in the early 2000s, it got replaced by another problematic chemical group called Organophosphate esters (OPEs). Since then the use of OPEs increased ...

Fresh approaches to processing GRACE data

To document large-scale transformations on Earth, such as waning ice sheets and shifting coastlines, geoscientists often use views from space to track mass changes on daily to decadal timescales.

There are deposits of ice at Mercury's poles, too

Although the Arecibo radio telescope is no more, it continues to deliver scientific discoveries. There is a wealth of Arecibo data astronomers continue to mine for new discoveries, and one of them is thanks to an astronomical ...

Smoke from major wildfires destroys the ozone layer, study shows

A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.
