Washington (Reuters) – James Webb Space Telescope noticed two large planets at different stages of infancy – one with atmosphere filled with dusty clouds and the other surrounded by a material disc – orly a young sun -like star, we discover the complex nature of planetary systems.
The two giant planets, which are more massive than the largest planet in our solar system, Jupiter, were directly depicted in the planetary system located in the Milky Way Galaxy, about 310 light -years from the Earth, in the direction of the Constellation Musca. The year of light is a distance of distance per year, 5.9 trillion miles (9.5 trillion km).
Since 1990 Astronomers have discovered more than 5900 planets for our solar system, known as exoplanets, less than 2% of them are directly portrayed as these two. In the early stages of development, they rarely find exoplanets.
The birth of the planetary system begins with a large cloud of gas and dust called a molecular cloud that collapses under its severity to form a central star. The rest of the material rotating around the star on a protoplanetary disk forms a planets.
Webb noticed this planetary system very early in his development history. The star named Yses-1 is about the same mass as the sun. Two planets fly away from the star, each probably it took thousands of years to fill one orbit.
Although the sun is about 4.5 billion years, this star is about 16 million years old, which is a real newborn. Researchers were surprised to learn that the two newborn planets that Webb watched seem to be at different stages of development seems to be.
I argued about two times the mass of about 14 times more than Jupiter and a star or a star at a distance of 160 times more than the Earth in the sun and more than five times to the outer planet of our solar system Neptune.
The planet is surrounded by a small grain dust disc, a condition that can be expected in a very early formation stage when it is still fused, or perhaps if there is a species or moon collided. Webb noticed water and carbon monoxide in his atmosphere.
The outer mass of the planet is about six times larger than Jupiter and the star is 320 times the distance to the sun. Its atmosphere is loaded with silicate clouds, different from the gas giants of our solar system. Webb also discovered methane, water, carbon monoxide and carbon dioxide in the atmosphere. It does not contain a disk of the material.
The combination of these two planets in the same system shows “the complex landscape that is the formation of the planet and shows how much we really do not know how the planets, including our own,” said Astrophysic Kielan Hoch of the Space Telescope Institute in Baltimore.
“Theoretically, the planets should develop at about the same time, as the formation of the planets occurs quite quickly, about a million years,” said Hoch.
A real secret is the place where the planets have formed, Hoch added, noting that their orbit’s distance from the host’s star is greater than it could be expected if they were formed on a protoplanetary disk.
“Also, why one planet still retains the material around it, and one has different silicate clouds, remains a big question. Do we expect all giant planets to form the same and look the same if they are formed in the same environment?
In addition to the fact that since 2022 Not only did it accumulate discoveries about the early universe, but it also contributed significantly to exoplanets with their observations almost and in the wavelength of the middle infrared.
“Webb reveals all atmospheric physics and chemistry that takes place in exoplants we used to not know, and is currently challenging every atmospheric model we used against Webb,” Hoch said.
