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

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 ...

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.

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.

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 ...

A newly found icy object, Ammonite, may be a 4-billion-year-old fossil from the Solar System’s edge—and it’s casting doubt on the Planet Nine theory.

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.

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 ...

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.

The newborn planetary system is emerging around Hops-315, a baby star around 1,300 light-years away. In a first, astronomers have observed the very early stages of the creation of a new solar ...
