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.

NASA develops technology to dissect the lower atmosphere

The part of the atmosphere closest to the planet is the hardest to measure from space due to the volume of gases above it. Studying Earth's planetary boundary layer, or PBL, will enable scientists to better understand the ...

Polar ice contaminated with nanoplastics

Decades-old polar ice contains significant amounts of nanoscale plastic particles. Studying ice cores from Greenland and Antarctica, an international team of scientists have identified several types of nanoplastic particles, ...

Sauropod dinosaurs were restricted to warmer regions of Earth

Giant, long-necked sauropods, thought to include the largest land animals ever to have existed, preferred to live in warmer, more tropical regions on Earth, suggesting they may have had a different physiology from other dinosaurs, ...

US study: Record highs, rain and beaver damage in Arctic

The Arctic continues to deteriorate from global warming, not setting as many records this year as in the past, but still changing so rapidly that federal scientists call it alarming in their annual Arctic report card.
