What happened

New observations of some of Neptune‘s moons and rings are providing evidence of a catastrophe that occurred billions of years ago around the solar system’s outermost planet in which a Pluto-sized interloper caused a celestial demolition derby.

Why it matters

Researchers used Nasa’s James Webb Space Telescope to examine the composition of three of Neptune’s small inner moons − Proteus, Larissa and Galatea − and its inner dusty rings and detected clay minerals that one might expect to find deep inside certain…

Common ground

These magnesium-rich minerals are known to exist on the dwarf planet Ceres, which orbits in the main asteroid belt between Mars and Jupiter, and in some meteorites.
