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

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 ...

Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic fields and water-driven alteration on its parent body.

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

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

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 ...

In A Nutshell Arrokoth, a snowman-shaped object billions of miles from Earth, is one of the oldest and least-disturbed relics of the early solar system Scientists have long debated whether its two ...

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

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...
