It's the first time in 15 years that the southern face of Saturn's rings will reach a tilt of 3". It will be visible through ...

On July 30, 1610, the famous astronomer Galileo Galilei became the first to observe rings around the planet Saturn. Shortly ...

And one day, the solar system will cease to exist. But when will the solar system end? And how will it die out? The answers to those questions depend on how we define the death of the solar system.

Challenging the timeline of the early solar system First, the Open University researchers proved the meteorite came from the outer part of the solar system based on its ratio of chromium and oxygen.

Some of these flecks are even older than the Solar System itself—the presolar grains in the Murchison meteorite, for instance, go back 7 billion years.

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same time, challenging current models of our solar system’s evolution.

In this artist’s impression, a comet erupts with jets of gas as it falls toward the sun from the depths of the outer solar system.

Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have looked like billions of years ago. The star is surrounded by a ...

Just the third-ever confirmed interstellar object has been detected in our solar system. Here's what we know. (Spoiler: It's not aliens.) ...

Astronomers have discovered the earliest seeds of rocky planets forming around a baby sun-like star, an unprecedented snapshot of "time zero," when new worlds begin to gel.

New simulations suggest that up to four of the solar system's rocky planets, including Earth and a long-lost world, once orbited in mathematical harmony around the infant sun. Analysis of an ...

Why sunspots are able to last so long has been a mystery for millenia, but a new observation technique revealed their secret. The equilibrium between magnetic fields and pressure allows the solar ...
