For centuries, astronomers have sought to understand the formation and evolution of the solar system and the dynamics that govern it. In particular, there is the long-standing question of whether ...

For two decades now, the iconic twin Voyager spacecraft have been quietly overturning everything we thought we knew about the boundary between our solar system and interstellar space ...

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

In short, dynamical studies of the solar system have generally failed to consider the influence that passing field stars will have on the solar planets over time. According to a recent study by a ...

How Did the Solar System Form? The tale of our sun may begin with another star: a predecessor whose fiery death brought about the birth of our solar system.

Astronomers believe they've discovered a spiral structure inside the Oort cloud that surrounds our solar system.

Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system.

Based on 20 years of observations by NASA’s Hubble Space Telescope, new research sheds light on one of the solar system’s most mysterious planets.

A nearby star drifts into the outskirts of our solar system. Its gravity disturbs the Oort Cloud and alters the orbits of far-out objects.

A new astronomical study suggests that Earth could one day be ejected from the solar system, not by the aging of the Sun, but by the unpredictable trajectory of a rogue star. While such a scenario ...

(Reuters) -The robotic Solar Orbiter spacecraft has obtained the first images ever taken of our sun's two poles as scientists seek a deeper understanding of Earth's host star, including its ...
