In a major discovery, scientists have discovered a cloud-like scattering of stars over the United States Milky Way. Though thought to be spherical for decades, with improvements in modern technology, new models show that these decaying clouds, called stellar halos, are in an oblique state.
This study was published in The Astronomical Journal. It features research related to a variety of astrophysics topics. The results provide details of the galaxy and the evolution of the galaxy. It also provides details on the search for a mysterious substance popularly called dark matter.

According to Jiwon “Jesse” Han, lead author of the study, the team measured the shape of the stellar halo with much greater precision than previously possible. He further stated that Steller’s halo resembled the shape of a rugby or soccer ball. Affirming the point, co-author Charlie Conroy notes that for decades, stellar halos were thought to be spherical or isotropic, and now we need to get rid of images of galaxies surrounding spherical stars. report ANI.
It should be noted that stellar halos are believed to be the visible region of what is known as the galactic halo. This galactic halo is controlled by dark matter, the existence of which is measured by its gravity. More importantly, each galaxy has its own dark matter halo. Visible matter causes star formation.

According to Han, star halos are a great place to start if anyone wants to learn about galactic halos in our galaxy. But for a long time it was believed that the stellar halo of the Milky Way is several thousand years old in our galaxy.
The stellar halo contains only one percent of the stars in our galaxy. Over the years, astronomers have identified thousands of stars found here.
