Astronomers photographed a baby planet, WISPIT 2b, during its formation process within a dusty ring around its star system.

Just because Pluto was ruled out as a planet in 2006 doesn’t mean our solar system only has eight planets. The search for Planet Nine is far from over as scientists continue to uncover clues ...

When 'Oumuamua traversed our solar system in 2017 it was the first confirmed Interstellar Object (ISO) to do so. Then in 2019, Comet 2l/Borisov did the same thing. These are the only two confirmed ...

Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have ...

There's a class of objects in the cosmos that are neither stars, nor are they quite planets. Astronomers used the powerful James Webb Space Telescope to sleuth out some of these objects, called brown ...

Astronomers have been fascinated after spotting an object earlier this year that came from interstellar space as is now hurtling through our inner solar system. Regardless, it’s an interesting visitor ...

Researchers at the California Institute of Technology (Caltech) have found new evidence that further suggests there is a ninth planet in our solar system. Nicknamed "Planet Nine," researchers said ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course. When ...

Astronomers have been finding planets around distant stars for more than a decade now, and the count is currently around 400. But the vast majority of these so-called exoplanets have been seen ...

There's a class of objects in the cosmos that are neither stars, nor are they quite planets. And with this new research, scientists have improved our understanding of these elusive free-floating ...
