A team of astronomers reached the first conclusive evidence of frozen water, outside the borders of the solar system, in a dust wreck disk that revolves around the sun -like star, 155 light -years away, using detailed data known as the spectra from the James Web Space Observatory.
Hard frozen water was found in a dust wreck disk surrounded by the star “HD 181327”, a young star like the sun, that is, in the stable part of his life cycle, located about 169 light years away in the constellation of the painter.
Special type ice
The results were published in a new research paper in the journal “Nature”, and researchers used the nearby infrared “Nir Speak” on board the James Web Space Observatory, a highly sensitive tool for very low dust molecules that can only be discovered from space.
“Discover an unambiguous web not only the water ice, but the crystal water ice that is also in sites like Saturn and the ice bodies in the Kper belt in our solar system,” said Chen Xih, the main author of the new research paper and a assistant researcher at the Johns Hopkins University in Baltimore, Maryland, in a press release of NASA.
All the frozen water discovered by James Webb is associated with accurate dust particles throughout the disk, and Shih said that the HD star 181327 “is a very active system, and there are regular and continuous collisions in his debr -disk, and when these ice objects collide, they launch small molecules of dusty water ice with the ideal size that a web telescope can discover.”
Drill tablets
Hadqam tablets are small, stereotypes of asteroids, comets, etc., and dust of micro -sizes.
Because frozen water is the most frozen volatile material, it plays an essential role in the formation of planets and small bodies, and although the presence of aqueous ice is common in the bodies of the Cibar belt and comets in the solar system, there is no conclusive evidence of the presence of water ice in the debris tablets before this study.
It is likely that the Cber Cyber for our solar system was one day similar to the HD 181327 debris disk.
