the protoplanetary disk of our solar system had to have been doughnut-shaped because the refractory metals could not have crossed the large gaps in a target-shaped disk of concentric rings.

Things were very different back then. We used to think the early solar system looked a bit like a dartboard, with concentric rings of material orbiting our sun. But a team of researchers now ...

By studying the present state of our home planet and other objects in the Solar System, researchers have developed a ... time a complex structure in which dust piles up in three concentric rings in ...

the composition of asteroids in the outer Solar System requires the cloud of material to be donut-shaped, rather than a series of concentric rings in a flat disk. This suggests that the first ...

A stunning image from the James Webb Space Telescope revealing concentric ... star system. The research is the first to have found evidence of starlight moving visible matter beyond our solar ...

Enormous rings may have graced many of the planets in the early solar system, giving rise to the moons that circle them today, scientists say. A new computer model suggests that the natural ...

The ring system is around a dwarf planet, named Quaoar, which is approximately half the size of Pluto and orbits the sun beyond Neptune. The discovery, published in Nature, was made by an ...

A ring that scientists had thought couldn’t exist has been found around a planet in our Solar System. The ring is similar to those that famously wrap around other nearby planets, such as Saturn.

Rings are special, dazzling rarities in our solar system. Now, astronomers have found that an extremely distant world — beyond even Pluto's orbit — is encircled with unusual rings. Scientists ...

Here’s how it works. Astronomers have discovered an entirely new ring system within the solar system, and it's located at such a great distance from its dwarf planet parent that it should be ...
