The Moon was a lot closer to Earth 2.46 billion years ago, and the shorter distance contributed to shorter days.
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.
Laboratory experiments show that earthquakes may have helped early life evolve in an oxygen-free world.
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.
New data on ancient zircons points to a transition from stagnant lid to subduction style tectonics at 3.6 Ga ago.
Lightning could have sparked the beginnings of life, but the primordial atmosphere might have made it more difficult for lightning to initiate.
How did our planet avoid being frozen solid during the early days of our solar system?
Researchers who study the formation of Earth show how ingenuity can shed light on hidden moments of creation.
Scientists studying South Pacific earthquakes suggest that an ultralow-velocity zone at the core-mantle boundary may be a remnant of a molten early Earth.
Early Earth conditions and the chemistry that led to life were inextricably interwoven. Earth scientists and prebiotic chemists are working together in new ways to understand how life first emerged.
