There are a couple of ways that scientists can date planets, so which planets formed first in our solar system?

The James Webb Telescope captures the beginning of planetary formation around the young star HOPS-315 for the first time.

New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, ...

What's special about Chiron's rings is that they're still forming; this marks the first time astronomers have ever seen a ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

CAPE CANAVERAL, Fla. — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

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 ...

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 ...

Material around Chiron, a small icy world in the far reaches of the solar system, may be taking shape into a ring system of ...

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