Saturn’s rings may be no more than 400 million years old
An analysis of data from NASA’s defunct Cassini probe suggests Saturn's rings materialized more than 100 million years after trilobites appeared on Earth.
- Environment
More than half of the world’s largest lakes are drying up
Satellite data from 1992 to 2020 reveal that 53 percent of the world’s largest freshwater bodies shrank during that period while only 24 percent grew.
- Climate
Thawing permafrost may unleash industrial pollution across the Arctic
As the frozen ground warms due to climate change, industrial pollutants could flow free from thousands of sites across the Arctic.
- Planetary Science
Seismic waves crossing Mars’ core reveal details of the Red Planet’s heart
NASA’s InSight lander observed a quake and an impact on the farside of Mars, allowing researchers to measure physical properties of the planet’s core.
- Planetary Science
Baby Jupiter glowed so brightly it might have desiccated its moon
During its infancy, Jupiter may have glowed about 10 thousand times brighter than it does today, which may explain why its moon Io is completely dry.
- Agriculture
