Manganese oxides are thought to be a signature of atmospheric oxygen. But on the Red Planet, recent results suggest they might be more of a red herring.
Space and ocean scientists take a splash course in multidisciplinary science to chart our solar system’s ocean worlds.
If geysers from Saturn’s moon Enceladus contain amino acids, new research shows that a spacecraft could collect them with signatures of possible life preserved.
New observations of the Venusian atmosphere collected from an airborne observatory showed no sign of the potential biosignature gas, casting additional doubt on a previous report of its detection.
Para determinar cómo los elementos cruciales para el desarrollo de la vida llegaron a la Tierra, los científicos estudian los gases nobles. Actualmente, métodos mejorados traen consigo nuevos indicios a partir del criptón, el gas noble más enigmático.
The discovery of tiny crystals of the iron-rich hydroxychloride kuliginite in New Caledonia provides new insights into the hydrogen production from mantle rocks and saline water.
Laboratory experiments show that earthquakes may have helped early life evolve in an oxygen-free world.
Gravity field measurements from decade-old lunar orbiter provide a proxy for counting craters.
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
Lightning could have sparked the beginnings of life, but the primordial atmosphere might have made it more difficult for lightning to initiate.
