Not exact matches

The basic architecture of our solar system, where things go in circles, and there are small rocky planets close to the sun and big massive gas giants far from the sun, is certainly not the only architecture.

Only rocky, sturdy planets could form nearby; giant planets would form farther out, where ices and cool gases could gather together.

«I would be cautious,» Nielsen says, about saying that gas giants are the only way to bring water to rocky planets.

Current theory holds that giant planets can form only at comparatively great distances from a star, where cold temperatures allow ice and frozen gases to gather together.

Another embryonic giant planet could easily have formed there, only to be booted outward by a gravitational kick from another gas giant.

In fact, while methane is a atmospheric characteristic of giant gas planets like Jupiter, the only brown dwarf found to even have a trace of methane was Gliese 229 B, which orbits a reddish, M - class dwarf located about 20 light - years away from Earth.

Despite being nearly three times as massive as Jupiter, the new planet (KELT - 9b) is only half as dense as the gas giant, as the radiation from its host star has caused its atmosphere to expand, the authors said.

In stark comparison, HAT - P - 26b has a metallicity of just 4.8 times that of the Sun, suggesting that not only is it closer to the gas giants in composition but also that it likely formed closer to its host star than the planets of a similar size in our own system.

The map provides a tantalizing glimpse of giant filamentary structures extending across millions of light - years, and paves the way for more extensive studies that will reveal not only the structure of the cosmic web, but also details of its function — the ways that pristine gas is funneled along the web into galaxies, providing the raw material for the formation of galaxies, stars, and planets.

Combining all of the measurements across the entire field of view allowed the team a tantalizing glimpse of giant filamentary structures extending across millions of light - years, and paves the way for more extensive studies that will reveal not only the structure of the cosmic web, but also details of its function — the ways that pristine gas is funneled along the web into galaxies, providing the raw material for the formation of galaxies, stars, and planets.

There is great variation in the length of day between the planets, with Venus taking 243 Earth days to rotate, and the gas giants only a few hours.
