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 ...

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 ...

When planetary rings are mentioned, the image of Saturn immediately comes to mind. However, this celestial feature is not ...

The space object, named Chiron, is believed to be a piece of rock measuring a whopping 130 miles wide at its broadest point - ...

Although it's smaller than a planet, Chiron could be a natural laboratory for learning about how ring systems form, change, ...

Material around Chiron, a small icy world in the far reaches of the solar system, may be taking shape into a ring system of its own. The rare event is unfolding in real time, giving astronomers a ...

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.

Super-Earths and sub-Neptunes, planets with sizes between Earth and Neptune, constitute approximately one-third of known exoplanets but are absent in our solar system. Their prevalence elsewhere and ...
