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 ...

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 ...

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 ...

In the swirling clouds of gas and dust that surround newborn stars, planets begin to form. These planet-forming disks are ...

Astronomers have discovered more than 300 exoplanetary systems that have three or more known planets. Most of these planets are about the same size and spaced close together, earning them the moniker ...

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

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.

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 ...
