Scientists and philosopher team up, propose a new way to categorize minerals

Scientists propose a new way to categorize minerals by incorporating historical data, highlighting the importance of understanding a sample's formation process. The IMA system is criticized for being time-independent, while the proposed approach uses 'historical natural kinds' to reflect changes in Earth's diversity.

Where were Jupiter and Saturn born?

A team of scientists, led by Matt Clement, used simulations to study the formation of Jupiter and Saturn. The findings suggest that these two planets were originally closer together than previously thought, with a ratio of two Jupiter orbits to one Saturnian orbit being more consistent with the current configuration.

Iron-rich meteorites show record of core crystallization in system's oldest planetesimals

Researchers uncover new details about the oldest planetary objects in our Solar System, which formed iron-rich meteorites. The distinct chemical signatures of these meteorites can be explained by core crystallization in their parent bodies, deepening our understanding of the geochemistry occurring in the Solar System's youth.

How does Earth sustain its magnetic field?

The geodynamo generates Earth's magnetic field through the motion of liquid iron in the outer core. New research examines how lighter elements like silicon could drive this process, suggesting a concentration of 8 weight percent silicon is sufficient to sustain the geodynamo on heat transmission alone for the planet's entire history.

How Enceladus got its stripes

The study investigates the physical forces acting on Enceladus that allow the tiger stripe fissures to form and remain in place. The researchers found that the fissures could have formed on either pole, but the south pole's unique deformation led to their formation.
