A group of Australian astronomers have revealed that they have identified five planets in the Solar System with the most “fiery” colours.
The researchers say that the five planets orbit their host star in a region called the “golden ring”, with each planet having its own unique colours.
This image from the Hubble Space Telescope shows the ring of planets around a star called HD 144634b.
It’s the same ring of planetesimals seen around a gas giant called HD 132667b, which is also the most famous and brightest star in our galaxy.
The researchers found that the planets are the most diverse in terms of colour in the solar neighborhood.
“We’re seeing the most planets that are very different in colour from the solar disk, which means that these planets have different atmospheres, different geology and surface features, and that’s a big surprise,” Professor Andrew Walker from the University of Melbourne told ABC Radio.
“[These planets] have all got different compositions.”
“There’s not really one uniform, universal colour for all of these planets, so you have a lot of variability, in terms the colours that they might have, and a lot that they’re in the same star formation environment, or similar star formation environments,” Professor Walker said.
“So, that’s exciting.”
Professor Walker said that the astronomers were able to see the differences in brightness because of a phenomenon called radial velocity, which allows the starlight to be pulled apart by the gravitational pull of the planets.
Professor Ryan Jardine, from the Australian Space Agency’s (AUSA) Jet Propulsion Laboratory, said the researchers were looking at how much these planets would interact with the stars they orbit.
He said that while some of the “green” planets were in the outer solar system, some were farther out, and therefore closer to the star.
When a planet orbits the star, its orbit takes it closer to its host star, and its mass is pulled closer to that star, Professor Walker explained.
As the planets move closer, the density of the gas in the system increases, which causes the planet to grow in size.
One of the more interesting discoveries is that one of the most common types of planet found in our solar system is a gas-giant.
In our solar neighborhood, there are more gas giants than planets.
In fact, the closest star to our Sun, HD 1451, is just three light-years away.
However, the planets in our Solar System are in the region called “Goldilocks”, which is where a small amount of mass is locked into a very large, dense, star.
The team says this suggests that this is an area where gas giants can exist, but are rare.
“What we’re seeing here is that there’s a little bit of gas that is locked in a gas giants, and we’re finding that there are planets around gas giants,” Professor Jardines said.
Professor Walker, who is a senior scientist at the Jet Propulses Laboratory, told ABC News that there was a “pretty strong relationship” between mass and mass-density in our Milky Way. “
So we’re actually finding that the gas giants are not that common, because they’re not that dense.”
Professor Walker, who is a senior scientist at the Jet Propulses Laboratory, told ABC News that there was a “pretty strong relationship” between mass and mass-density in our Milky Way.
But he said it was unclear what this relationship was for the planets orbiting around their host stars.
“We don’t know if these planets are rocky, or gas giants or something else, and it’s a bit of a mystery, and so I think the best thing to do would be to try to model these planets from the perspective of the stars,” he said.
“But then, you know, the models are just models.”
But Professor Walker is not against the idea of having planets orbiting stars.
If they could be found, he said, they would have a unique “environment” that would allow them to form life.
“If there are worlds orbiting stars, you could probably form life on them,” he told ABC.
