Team identifies parent body materials in Ryugu asteroid

An international team including a researcher from Lawrence Livermore National Laboratory (LLNL) has determined that one specific particle on the asteroid Ryugu can shed light on the unaltered initial materials from its parent ...

New model shows Earth's deep mantle was drier from the start

Earth's mantle is the thick layer of silicate rock between Earth's crust and its molten core, making up about 84% of our planet's volume. The mantle is predominantly solid but, on geologic time scales, it behaves as a viscous ...

Dying stars could seed interstellar medium with carbon nanotubes

Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation ...

Earth and Mars were formed from inner solar system material

Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of researchers led by the ...

Finding the source of the impactor that wiped out the dinosaurs

The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 66 million years ago likely came from the outer half of the main asteroid belt, a region previously thought to produce few impactors. ...

Scientists find carbon-rich liquid water in ancient meteorite

Water is abundant in the solar system. Even beyond Earth, scientists have detected ice on the moon, in Saturn's rings and in comets, liquid water on Mars and under the surface of Saturn's moon Enceladus, and traces of water ...
