The inner solar system spins much more slowly than the laws of modern physics predict, and a new study may help to explain why. A thin disk of gas and dust — known as an accretion disk ...

The research, ‘Neutral-charged-particle Collisions as the Mechanism for Accretion Disk Angular Momentum Transport‘, was published in the Astrophysical Journal. More about solar system Mystery ...

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

Researchers have discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.

In this video segment adapted from NOVA, learn how our solar system formed from a cloud of gas and dust more than 4.5 billion years ago. Watch video that features real satellite imagery as well as ...

Ziliang Jin, Maitrayee Bose, Tim Lichtenberg, Gijs Mulders We investigated the hydrogen isotopic compositions and water contents of pyroxenes in two recent ordinary chondrite falls, namely ...

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 ...

An "interstellar object" is speeding toward the inner solar system, where Earth is located, astronomers have confirmed.
