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 ...

A group of astronomers has found a solar system 116 light-years from Earth that seems to challenge current theories about how ...

Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma. They’ve discovered the first “binary-binary” – ...

A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...

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 ...

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

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 ...

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 ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...
