The search for life on Mars involves the efforts of scientists from many different disciplines. An important aspect of that search is to study Martian sedimentary rocks for information about […]
In the whole history of Earth’s climate, few events are as extreme as those that geologists call “Snowball Earth.”
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of […]

An eruption of Old Faithful Geyser in Yellowstone National Park is a sight to behold. Indeed, millions of tourists flock to the park each year to see it. Hot water […]
The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to […]
Tens of tons of extraterrestrial solid material collide with Earth daily. Most of this material is small enough that it burns up in the atmosphere, but some fragments are large […]
While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of […]
