A groundbreaking study published in Communications Earth & Environment has called into question the long-standing assumptions ...

Rocky bodies called protoplanets were thought to have formed slightly earlier in the inner solar system than those beyond the ...

Ancient meteorite reveals a protoplanet formed in the outer Solar System earlier than thought, reshaping planet formation ...

A small, inconspicuous meteorite may be about to change our understanding of how and when our solar system formed. Tiny shavings from the meteorite Northwest Africa 12264 are challenging the long-held ...

The Sun's expansion into a red giant will engulf the inner planets, drastically increasing temperatures in the outer solar system. The habitable zone will expand to 10-50 AU, potentially making ...

This link, called "trapping efficiency," shows how often scattered planets end up in stable wide orbits. The research found that in solar system-like conditions, trapping happens about 5–10% of ...

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new ...
