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. Previous research suggests ...

Researchers rarely get a glimpse of an interstellar object up close like 3I-ATLAS, so they have jumped on the opportunity to learn about its composition, which can reveal how planet systems are made.

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 ...

As our solar system formed, tiny particles in the disk around the young Sun gradually grew larger until they became the size of small pebbles. "Once pebbles grow large enough to no longer travel along ...

Discovery of oxygen raises new questions about how solar system formed. In this undated photo, Rosetta finds oxygen on comet 67P. ESA/Rosetta/NavCam – CC BY-SA IGO 3.0 — -- The European Space ...

The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...

Astronomers have witnessed the creation of a solar system for the first time. Data captured by the ALMA telescope in Chile and the James Webb Space Telescope showed planets forming around a star in ...

The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas ...

Webb just spotted a carbon-rich moon factory 625 light-years away, revealing how moons like ours may have first taken shape.
