The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...
Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...
The solar system moved through a star-forming area near Orion. This event might have increased interstellar dust around Earth ...
Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...
Mar. 11, 2025 — A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that are 1 to 4 times the size of Earth and among the most common in ...
Light gases like helium hung around in the gas-and-dust nebula that formed the solar system for only a few million years. "It's very much debated how long it took the Earth to form," Olson said.
