Astronomers have traced the growth of Earth's solar system back to its cosmic womb, before the sun and planets were born. The solar system coalesced from a huge cloud of dust and gas that was ...

The dust grains that eventually coalesced into our solar system's planets nearly 4.6 billion years ago likely bounced around like pinballs over vast distances, new study suggests.

Missing The solar system once had five giant gaseous planets rather than the four it has today. That's the conclusion from a computer simulation of the solar system's evolution, which suggests the ...

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

"When samples such as the remnants of this event are collected and studied, they enhance our understanding of the origin and evolution of our solar system," NASA representatives wrote.
