To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials ...

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 ...

Paleomagnetic analysis of 28 Ryugu asteroid particles reveals stable magnetization acquired within millions of years of solar ...

Active small bodies—including comets, active asteroids, icy minor planets, and transitional objects—occupy a unique position in planetary science. As ...

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at ...

Might the first moments of planet formation be more understandable than ever before? Fresh observations suggest that the creation of worlds such as our own is perhaps happening right in front of us, ...

Scientists have recently unveiled a remarkable discovery in the outer reaches of our solar system: a space fossil located 4 billion miles past Pluto, covered in unidentified organic molecules. This ...

The outer reaches of our Solar System continue to reveal a complex dynamical environment where the interplay of gravitational forces shapes the orbits of a myriad of distant bodies. Research in this ...

There’s a bit of a paradox about our galaxy: it’s both jam-packed with stars and cavernously empty. The Milky Way is crowded in the sense that it holds hundreds of billions of stars, as well as ...

For a long time, engineers have contented themselves with setting strict degradation and unavailability numbers, often guided by an independent engineer’s recommendation, and handed those assumptions ...
