Earth’s earliest forest revealed in Somerset fossils

The eruption and volcanic material sedimentation processes of giant caldera eruptions are not well understood, making it also difficult to estimate their size. Kobe University researchers used seismic reflection surveys to visualize the sedimentary structure and analyzed collected sediment samples, enabling them to obtain important information on the distribution, volume, and transport mechanisms of the ejecta. © SHIMIZU Satoshi (CC BY)

Satellite image of gully landscapes on Mars, taken by HiRISE (High Resolution Imaging Experiment), a camera on board the Mars Reconnaissance Orbiter (photo no.: ESP_039114_1115). The white CO2 ice is visible on the sides of the gullies.

Surprising insights about debris flows on Mars

Grand Prismatic Spring in Yellowstone National Park, seen here from an aerial photo, provides a modern-day glimpse into the types of environments where sulfites may have accumulated and possibly played a role in kick-starting the earliest life on Earth.

Sulfur and the origin of life

Scientists analyzed mercury levels from core samples from the Mochras Farm (Llanbedr) borehole in Wales to estimate how much and how rapidly carbon was released during ancient volcano events in Earth's history Credit: Stephen Hesselbo. All Rights Reserved.
