Scientists have long been asking an important question for astronomy: how many stars are there? satellite galaxies of the Milky Way? This is our galaxy. Many stars orbit around it. satellite galaxiesthe number of which has not yet been identified. Researchers believe it is important to discover it to unravel the many mysteries that still circulate about the dark matter.
Furthermore, this research could help us learn more about how galaxies work and how they change and evolve over time. The research group is aware of about sixty dwarf galaxies that orbit our galaxy, but studies suggest that there may be a greater number. Among the most famous dwarf galaxies are the Magellanic CloudsIn the study, the team used a new tool, the Subaru telescopelocated atop Mount Maunakea, Hawaii.
Virgo III and Sextans II: The Two New Galaxies, an Important Discovery
Virgo III e Sextans II it’s two new satellite galaxies that have been identified by the group of researchers. A revelation that allows to increase those known, but which to date, in total are nine and represent a very small number.
Scientists estimate that the satellite galaxies around the Milky Way there must be about 220, perhaps even more. The weak matter that composes them and other details, as well as perhaps the distances, do not allow us to identify them all in the cosmos closest to us. This was another goal achieved that gives hope to scientists, who in the future will use another instrument with superior performance.
A step forward for the study of dark matterwhich according to some scientists’ hypotheses, could be composed of small primordial black holesScientists say that over years of studying dark matter they have discovered that it is the same substance that makes up vast halos surrounding large stars. galaxies. According to their findings, halos composed of this dark matter could be linked to the origins of large galaxies, such as our own Milky Way.
