For first time, Webb telescope discovers an alien planet

Washington (Reuters) -In addition to providing information about the universe, James Webb Space Telescope since the 2021 launch has obtained valuable data about various planets already known beyond our solar system. Now, for the first time, WebB discovered an unknown outer planet before.
Researchers said that wet displayed a direct young gas giant planet in the size of Saturn, the second largest planet of our solar system, and returned a smaller star than the sun, which is approximately 110 light years on the earth in Cremilia. Light year, distance light within a year, 9.5 trillion km (5.9 trillion miles).
Most of the 5,900 outer planets, which have been discovered since the 1990s, were detected by using indirect methods such as observing the lightwear of the light of lightweight of a star called transit when they were in front of a planet. As WebB did with the newly defined planet, less than 2% of them were viewed directly.
Although this planet is large considering in the context of our solar system, it is actually the least large discovered directly by imaging – 10 times larger than the previous registration holder. This talks about the sensitivity of WebB’s instruments.
This discovery was carried out using a corongrage produced by the French, a device that prevented bright light from a star, mounted on the Middle Infrared Instrument of WebB or Miri.
The French Research Agency, the chief author of the CNRs and the observer Wednesday, opens the opening of the outer planets of the outer planets of the outer planets of the outer planets, “Webb, mass and the star of a planet.
The planet orbits the host star called TWA 7, about 52 times more than the Earth’s orbit distance from the sun. To put this on the perspective, Neptune, the outermost planet of our solar system, is about 30 times more advanced than the Earth. The transit method of exploring outer planets is not much more like the newly defined, but is particularly useful to detect the orbit close to the host stars.
“Indirect methods provide incredible information for planets close to the stars. Imaging to identify and characterize the planets more, typically 10 times the Earth-day distance.” He said.
The birth of a planetary system begins with a large cloud of gas and dust, called the molecular cloud that collapses under its own gravity to form a central star. Protoplanetary disk form is the material that rotates around the star called planets.
The stars and planets in this research are about 6 million years old compared to the age of the sun and about 4.5 billion years old solar system – practically newborn.
Due to the angle where this planetary system was observed – the researchers were able to distinguish the remaining disc. It has two wide -centered ring -like structure of rocky and dusty materials and a narrow ring where the planet sits.
Researchers do not yet know the composition of the atmosphere of the planet, but future WebB observations can give an answer. In addition, they are not sure whether the planet is as young as it is, as well as the surrounding material, and still earns a mass.
Although this planet is the smallest viewed directly, it is much larger than rocky planets like the world that may be good candidates in search of life beyond our solar system. Even if the cosmos close infrared and mid -infrared wavelengths are the tremendous abilities of observation, webB still cannot view the external planets of the world.
“When we look forward, I hope that direct imaging projects of world -like planets and possible life symptoms will be real.” Lagrange said. ” He said.
