Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

Jupiter’s early growth carved rings in the solar system, delayed meteorite formation, and kept planets like Earth in stable ...

The solar system is 4.54 billion years old, based on rock dating. Gas giants (Jupiter and Saturn) likely formed first. Ice giants (Uranus and Neptune) probably formed next. Rocky planets formed last, ...

Did a massive ice giant planet once orbit in the outer solar system? And what could evidence for such a world teach us about the original positions of Jupiter and Saturn? The ancient Solar System was ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals ...

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 ...

In an article published in the journal Icarus, researchers at São Paulo State University (UNESP) and collaborators report the findings of a study reconstituting the formation of the dwarf planet Ceres ...

You're probably familiar with how the solar system looks today. There are eight officially recognized planets located more or less on the same plane, orbiting the sun. But have you ever given a ...

Comet C/2025 V1 (Borisov), discovered by an amateur astronomer, is captivating scientists. Its unusual orbit initially ...

Iron meteorites are remnants of the metallic cores of the earliest asteroids in our solar system. Iron meteorites contain refractory metals, such as iridium and platinum, that formed near the sun but ...
