A team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles ...

Cosmochemists now present the most comprehensive comparison to date of the isotopic composition of Earth, Mars and pristine building material from the inner and outer Solar System. Earth and Mars were ...

The presence of deuterium, an isotope of hydrogen, in 3I/ATLAS suggests the interstellar comet formed in a much colder place before our solar system existed.

To better understand why the planets have variable compositions, we have to first understand the process of how stars form. While the composition of gas and dust in a precursor molecular cloud is ...

SAN ANTONIO — November 12, 2024 — A Southwest Research Institute-led team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to ...
