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

A groundbreaking study in galactic archaeology proves the Sun made a treacherous journey to reach its current home in the ...

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 ...

Comet 3I/ATLAS, the third known interstellar object ever detected passing through our solar system, carries a chemical signature that does not match what astronomers typically see in comets born ...

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 ...

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 ...

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 ...

Astronomers studying a rare visitor from another star system have discovered something unexpected. The interstellar comet known as 3I/ATLAS appears to contain unusually large amounts of alcohol. While ...
