Jupiter’s icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international ...

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 new paper in Monthly Notices of the Royal Astronomical Society argues the simplest answer may work: contact binaries like Arrokoth can form directly during the gravitational collapse of a dense ...

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

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 ...

About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth’s chemical makeup solidified just three million years after the Solar System formed—yet it was a later collision with ...

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 ...

Jupiter, the largest planet in the solar system, may have been responsible for a mysterious age gap in the early solar system's planet building blocks. Credit: NASA / JPL-Caltech / SwRI / MSSS / Tanya ...
