our Galaxy According to new research, it’s not as completely mixed as scientists sometimes imagine.
In particular, the new study focuses on the distribution of what astronomers consider to be metals. This is all elements except hydrogen and helium, even if these elements are gases.In the new work, the scientist Hubble Space Telescope Chile’s ultra-large telescope maps dust metals throughout the Milky Way in the hope of improving the model that describes the history of the galaxy.
“Initially, Milky Way Annalisa De Cia, an astronomer at the University of Geneva in Switzerland and the lead author of the new study, said: statement.. “The stars gradually enriched the environment with the metals they produced.”
The enrichment occurs Performer Cores and atoms break together, slowly forming heavier and heavier types of matter, down to iron. Not all stars explode when they run out of material to fuel the process, but booming stars throw all their metals into the vicinity of the universe. Theoretically, the metal could mix with the rest of the Milky Way.
And traditionally, scientific models have, according to the statement, assumed that the mixing process is quite effective. New observations on dust near 25 different stars suggest that this may not be the case, and instead suggest that there are significant local differences in metal levels.
As a result, scientists may need to reassess their understanding of the history of the Milky Way, researchers said.
The study is explained in paper It was published in Nature magazine on Wednesday (September 8th).
