Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth ...

Astronomers propose a new hypothetical planet, Planet Y, beyond Neptune, based on observed orbital anomalies in the Kuiper ...

The European Space Agency-led Solar Orbiter mission has split the flood of energetic particles flung out into space from the sun into two groups, tracing each back to a different kind of outburst from ...

A Jupiter-like planet has been found orbiting a young sun-like star in a solar system far away in what is a potentially ...

Astronomers have picked up evidence of an Earth-sized world, distinct from the previously hypothesised Planet Nine and Planet ...

Beyond the familiar planets lies a fascinating frontier filled with icy worlds, mysterious orbits, and cosmic curiosities.

Astronomers have, for the first time, detected a planet growing inside a cleared gap of a protoplanetary disk, confirming long-held theories about how young planets shape their star systems.

Astronomers have discovered a brand new type of planet outside our solar system that, even in its infancy, is already bigger ...

The eight planets in our solar system orbit the sun in roughly the same plane, because they all originally formed from the same disc of debris around the sun. The line the sun traces across the ...

Astronomers using a pair of planet-hunting satellites discovered a solar system with at least six planets rotating around a star in perfect sync with each other.
