Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected.

Thanks to new measurements of very old meteorites, the current consensus on the Solar System's age is 4.5684 billion years old, with an uncertainty of 240,000 years—a tiny fraction of a percent.

She said: ‘It suggests that HOPS-315 can be used to understand how our own Solar System formed. This result highlights the combined strength of JWST and ALMA for exploring protoplanetary discs.’ ...

Our solar system formed from a dense cloud of gas and dust that collapsed into a swirling disk of matter, most of which gravitated to the disk's center — which would eventually become the sun ...

Though Pluto has formally been considered a dwarf planet for almost two decades, it still has many lessons left for planetary scientists — including hints about how the solar system formed.

Our solar system formed about 4.6 billion years ago, when a rotating cloud of dust and gas — the solar nebula — collapsed in on itself, forming the sun. But not all of that dust and gas became ...

But what exactly caused the formation of these chondrules remains unclear. “We have the same theories we had 50 years ago,” said study co-author and UChicago postdoctoral researcher Timo Hopp.
