When the solar system was first organizing itself, a disk of gas and dust took shape around the sun's central mass. It eventually sorted itself into the system of planets we see today. But there are ...

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

A groundbreaking study published in Communications Earth & Environment has called into question the long-standing assumptions about how our solar system came to be. Tiny shavings from a meteorite ...

Scientists at the Massachusetts Institute of Technology and other universities are analyzing tiny particles from a distant asteroid to learn more about how the outer solar system was formed and shaped ...

Our Solar System is believed to have formed from a cloud of gas and dust, the so-called solar nebula, which began to condense on itself gravitationally ~ 4.6 billion years ago. As this cloud ...

Astronomers have directly spotted a rare young planet, WISPIT 2b, still forming within the gap of a dusty ringed disk around a star like our sun—something long theorized but never observed until now.

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

In the remote outer reaches of planetary systems, far beyond the orbit of known planets, enormous and mysterious worlds silently loop around their stars. Some drift as far as 10,000 times the distance ...

We like to think that our solar system is eternal, but one day, its very epicenter will die. Our Sun, like all stars, had a ...
