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.

While the solar system is defined by the gravitational influence of the Sun, what lies above is a vast and largely unexplored region filled with fascinating phenomena.

A computer visualization maps small bodies in the solar system that are expected to be observed by the Rubin Observatory during the 10-year Legacy Survey of Space and Time. Red indicates near ...

Scientists have unlocked one of the solar system’s many secrets from an unexpected source: a planetarium show opening to the public on Monday. At the American Museum of Natural History last fall ...

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 ...

The simulation actually suggests that a planetary loss scenario happens sooner rather than later, making stellar field passage the main cause of instability in the Solar System for the next 4 to 4 ...

The chance of a planet forming in the outer reaches of the solar system – a hypothetical Planet Nine – could be as high as 40 per cent, but it would have been a rough start ...

Jupiter, the largest planet in the solar system, was 2 to 2.5 times bigger in its earlier life, according to new research. Credit: NASA / JPL-Caltech / SwRI / MSSS / Tanya Oleksuik Jupiter, the ...

Astronomers have announced the discovery of a new dwarf planet in our solar system, named 2017 OF201. Located far beyond Neptune, it orbits the sun every 25,000 years.

Jupiter is our solar system's biggest planet by far. It used to be twice as large: Study A recent study found that Jupiter was once twice the size that it is now, making it big enough to swallow ...

The Solar System has just gotten a new official member. Currently, with the name of 2017 OF 201, this is a trans-Neptunian object (TNO). This means that it orbits the Sun further away than Neptune.

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.
