From star to solar system: How protoplanetary rings form in primordial gas clouds. ScienceDaily . Retrieved April 25, 2025 from www.sciencedaily.com / releases / 2020 / 09 / 200915121328.htm ...

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.

The concentric rings in the trunk, besides indicating the age of the tree, also shed light on the corresponding weather conditions during each year ... The origin of Earth and the solar system ...

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 ...

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 ...

The most well-known ringed planet is Saturn; its rings are made up of thousands of thin, delicate concentric rings ... Why don't the moons in our solar system have rings when the giant planets ...

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.

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 ...

the rings appear to disappear from Earth's vantage point. NASA/JPL/Space Science Institute Saturn is the sixth planet from our sun, and the second-largest planet in the solar system, measuring ...
