How does frost form on Mars?
Astronomers discovered satellite images of morning frost on Mars’ volcanoes. They proposed that the frost is made of water based on…

Undergraduates at Trinity University summarize the latest research in Earth sciences!
When did freshwater appear on Earth?
Geologists found chemical ratios in ancient minerals that suggested Earth had freshwater 550 million years after it formed.
Is groundwater heating up?
Researchers modeled groundwater temperature trends from 2000 to 2100. They estimated that groundwater could warm by up to 3.5°C over the…
A new treasure trove of Cambrian fossils
Paleontologists discovered a new set of fossils from the ancient ancestors of animals in rocks from China.
Volcanism warmed past Earth
Geologists dated a global warming event about 180 million years ago. They found it lasted between 169,000 and 417,000 years and was linked…
Most river water comes from the ground
Hydrologists incorporated ground and surface water flow data into Earth System models. They used these models to estimate that nearly 60% of…
How did Venus’s Ishtar highlands form?
Researchers modeled tectonic and magmatic processes on Venus. They determined that its highlands formed when molten rock rose, melting its…
How complex plants reshaped the oceans
Researchers found that when complex plants evolved, they increased ocean oxygen and massively restructured the marine ecosystem.
Rising soil temperatures could stop forests spreading
Researchers found higher soil surface temperatures prevented seedling survival and forest expansion in low-elevation forests.
Geologists identify a new way copper ore forms
Researchers found that massive copper ore deposits in central Arizona formed from melted crust rather than melted mantle.
