Scientists discover strange matter in the atmosphere of the sun .. How does this affect our planet?
Scientists from Ireland and France have announced a major new discovery of how the substance behaves in the harsh conditions of the sun's atmosphere.
According to the site "phys", scientists used large radio telescopes and ultraviolet cameras aboard a NASA spacecraft to better understand the fourth state of matter. This issue, known as plasma, could be the key to developing safe nuclear power generators Clean and efficient on the ground.
The majority of the universe consists of plasma, a very unstable and electrically charged fluid, and the sun also consists of this plasma.
Although it is the most common form of matter in the universe, it is still a mystery, mainly due to the scarcity of natural conditions on earth that lead to this material, making it difficult to study.
Special laboratories on Earth re-create the harsh conditions of this material for this purpose, but the sun is a natural laboratory to study how plasma behaves.
Dr Ion Carly, a postdoctoral fellow at Trinity College Dublin and the Dublin Institute for Advanced Studies (DIAS), led the study. "The solar atmosphere is a hotbed of activity, with plasma temperatures exceeding 1 million degrees Celsius, particles moving near light speed, While bright light particles shine at radio wavelengths, so we are able to observe exactly how plasma behaves with large radio telescopes. "
"We have worked with the scientists at the Paris Observatory and have conducted solar observations through a large radio telescope located in Nansay, central France," he said.
"We have combined radio observations with UV cameras on board NASA's Solar Dynamics Observatory to show those plasma that are often emitted by the sun. We have known this activity for decades, but our use of space and terrestrial devices allowed us to photograph impulses Radio for the first time and see exactly how plasma become unstable in the solar atmosphere. "
The study of plasma behavior on the sun allows for a comparison of how it behaves on Earth. Great efforts are being made to build magnetic fusion fusion reactors – nuclear power plants that are safer, cleaner and efficient than the current fission reactor.
"Nuclear fusion is a different type of nuclear power generation that merges plasma atoms together rather than separating them like fission, fusion is more stable and safe, and requires no more high-grade radiant fuel," said Peter Gallagher, a professor at DIAS and a co-author of the project.
