Planetary scientists Paolo Sossi and Dan Bower from ETH Zurich have published a peer-reviewed study in Nature Astronomy arguing that Earth formed almost entirely from inner solar system material, with ...

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have ...

In this study, NRM measurements suggest that the observed characteristics of Ryugu particles is a chemical remanent magnetization, likely acquired during growth of framboidal magnetite that occurred ...

Some 4.6 billion years ago, when the solar system was born from a vast cloud that collapsed to form the sun and a surrounding disk of whirling gas, no planets yet orbited our star. Back then, besides ...

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from ...

Scientists may have found one of the main sources of rocky material for the solar system, forming diverse populations of baby planets over millions of years. In a recent study published in The ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

The standard story of the origin of our solar system has gone like this: 4.6 billion years ago, a giant cloud of dust hung frozen in space. Then the explosion of a nearby star caused part of that dust ...

When the solar system formed, a disk of gas and dust orbited the young sun. Over the course of millions of years, the dust gradually clumped together to form kilometer-sized chunks known as ...
