New modeling suggests giant, cool blobs of titanium-rich rocks sinking down to the ancient Moon’s hot core could have produced intermittently strong magnetic fields for the first billion years of the Moon’s history.
An upcoming lunar mission holds promise for elucidating geologic processes, including Sonia Tikoo's 2018 work to show how heating associated with magmatic activity within the Moon might have amplified localized magnetic fields.
A collection of research and insights from Stanford experts who are deciphering the mysteries and mechanisms of extinction and survival in Earth’s deep past and painting an increasingly detailed picture of life now at the brink.
The Chicxulub impact crater that is linked to the extinction of the dinosaurs hosted a hydrothermal system that chemically and mineralogically modified more than 100,000 cubic kilometers of Earth’s crust, according to new research.
"The general public knows a lot about the actual Moon landing but not much more about its scientific importance," professor Sonia Tikoo-Schantz says in the context of how the Apollo 11 mission has shaped our understanding of the Moon and Earth.
