Our Sun is actually a cosmic refugee. Around 4.6 billion years ago, it first ignited in a hostile, radiation-blasted neighborhood 10,000 light-years closer to the Milky Way’s center than it is now.

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

Most of our knowledge about the Solar System’s formation and evolution comes from the study of extraterrestrial rock samples called chondritic meteorites. These rocks, which are fragments of asteroids ...

University of Central Florida (UCF) scientists and their collaborators discovered new insights into the formation of distant icy objects in space beyond Neptune, offering a deeper understanding of our ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.
