![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 […]
An international research team involving the University of Cologne has found a new way to reconstruct how landscapes developed tens of millions of years ago and how long sediments remained […]
The Mesoproterozoic eon, often regarded as mundane and static, lays the foundation for dramatic transformations in Earth’s physical and biological evolution during the subsequent Neoproterozoic.
The first forms of life on Earth were microbial, preceding the evolution of multicellular life by more than two billion years.
Here, a straight-line feature cuts across many layers, seemingly changing their brightness and presumably indicating a major change in the layer properties.
Jarosite, a sulfate mineral widely detected across the Martian surface, has long been regarded as a key indicator of past aqueous activity.
