Pluto landed its largest moon, Charon, with a 'kiss'—overturning decades of scientific assumptions about how planetary bodies form and evolve. This is the conclusion of a new study, conducted at the ...

Billions of years ago, in the frigid outer reaches of our solar system, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like a celestial snowman, ...

How did Pluto and its largest moon, Charon, form? This is what a recent study published in Nature Geoscience hopes to address as an international team of researchers led by the University of Arizona ...

This artist’s concept depicts one of the solar system’s inner planets slamming into Earth after being nudged on a collision course by a passing star. Such a world-shattering cataclysm is extremely ...

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space’s oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.

Recent research utilizing advanced supercomputer simulations challenges the prevailing hypothesis that a giant impact formed Jupiter's dilute core. These simulations, incorporating a novel mixing ...
