In the whole history of Earth’s climate, few events are as extreme as those that geologists call “Snowball Earth.”
This scene from the eastern side of Terra Cimmeria, northeast of the Hellas impact basin, shows many impact craters of different sizes and types of preservation, with a few sharp-looking […]
The North Polar Layered Deposits (NPLD) are large layered deposits of dusty water-ice in the northern polar region of Mars. The layering we see is caused mainly by slight variations […]
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 […]
Gully and defrosting activity have been visible here along the edge of a dune field, along with blocks of frost. Observations of the same area help us check for repeat […]
![Contribution of springs to the lake. (A) Venn diagram of genera found in the Corral Springs biofilm, salt crust, Springs 1 and 2 (S1, S2 combined), Roberts Ranch/Wyman Creek (RS), and the lake water. (B) Mixing proportions calculated using SourceTracker using the lake water samples (LW1, LW2, and overnight incubated [ON]) and the salt crust as sinks, and the biofilm, RS, S1 and S2 as sources. “Unk” indicates “unknown source.” The Gibbs sampler was run for 10,000 iterations. -- Frontiers](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/02/Microbial-communities-of-selected.png?resize=1200%2C720&ssl=1)
Deep Springs Lake is a small, isolated, highly alkaline soda lake in Inyo County of Eastern California, USA. It is a seasonally filled salt lake or playa, and is part […]
The Martian brain terrain (MBT), characterized by its unique brain-like morphology, is a potential geological archive for finding hints of paleoclimatic conditions during its formation period.
Mass extinctions are extremely catastrophic events on Earth. Throughout Earth’s evolutionary history, numerous mass extinctions have occurred, with five major mass extinctions being particularly representative.
The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate […]
Using images from cameras on Mars orbiters, an international research team led by the University of Bern has discovered structures on Mars that are very similar to classic river deltas […]
