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, ...

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 ...

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 ...

Around the bright star Fomalhaut, astronomers spotted glowing clouds of debris left behind by colossal collisions between ...

What seemed like new planets around Fomalhaut were actually expanding dust clouds from violent planetary collisions seen by Hubble.

The early years of our solar system were a period of unimaginable chaos and violence, a gravitational free-for-all where colliding planetary embryos competed for survival. In this tumultuous ...

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 ...
