There is carbon dioxide For the first time, it was detected on the planet outside the solar system. The gas was directly observed by the James Web Space Telescope and belongs to the HR 8799 system located in 130 light -years on Earth on four alien planets. CO’s detection2 It provides a clue to how a distant planet is formed, and it provides strong evidence that these four huge planets are formed in the same way as Jupiter and Saturn through the slow formation of a hard core. There was a result Post In the most recent issue of the astronomical journal.
William Balmer, the author of Johns Hopkins University, said, “By detecting this powerful formation of these carbon dioxide, the atmosphere of this planet has a significant portion of heavy elements such as carbon, oxygen and iron. Considering what we know, this indicates that this was formed by the core acctreation that it is an interesting conclusion for the planets they can see. “
HR 8799 is a system born 30 million years ago and is younger than the solar system that has existed for 4.6 billion years. The planet of HR 8799 is still hot in violent formation. This provides scientists with valuable data on how it compares with the formation of stars or brown dwarfs.
Balmer said, “Our hope for this type of study is to understand our own solar system, life and ourselves, compared to other expression system systems.” We want to take pictures of other solar systems and see how they are similar to us. From there, we can try to understand how strange our solar system is and how normal it is. “
Carbon dioxide is an essential ingredient for developing life on Earth, making it a key goal to find life elsewhere in the universe.
Besides, joint2 When condensation with a small ice particles in the deep cold of the space, the presence can shine light on the formation of planets. Jupiter and Saturn are thought to have been formed through the process of creating a solid core after many small ice particles, and then absorbing gas and growing into a gas giant we know today.
Laurent Pueyo, the co -author of the astronomical Zayzer Paper of the Space Telescope Science Institute, said, How common is it in the long -range planet where we can direct images? We don’t know yet, but we suggest additional observation through Webb, which was inspired by carbon dioxide diagnosis of this issue.
Unlocking potential of James Webb Space Telescope
James Webb Space Telescope should also be given flowers. It shows that it can perform more than that inferring the atmospheric composition of the alien planet in the starlight measurement; In fact, it showed the ability to drop the chemical composition of the atmosphere as far as these.
In general, JWST can barely detect alien planets when crossing in front of the host star due to a large distance that separates us. However, in this case, the basis for revealing the hidden world by blocking JWST’s coronary measures is possible.
Balmer said, “When looking at the sky, the thumb is in front of the sun. This setting, similar to solar eclipse, allowed the team to find infrared rays in the wavelengths from the earth, which shows specific gas and other air details.
“These huge planets have a very important influence.” If this huge planet acts like a bowling ball that cruises our solar system, they can interfere with or protect the planet like us in any sense. Therefore, better understanding of their formation is important for understanding the formation, survival and habits of planets, such as the future.
