NASA's Hubble Space Telescope maps giant halo surrounding Andromeda galaxy

NASA’s Hubble telescope has mapped a giant halo around Andromeda galaxy, which is nearest from milky way. As per team’s findings, which were published in Astrophysics Journal on August 27,  invisible halo of diffuse plasma extended 1.3 million light-years from galaxy, which means it was alrey colliding with halo of Milky Way. Since scientists live inside Milky Way, y are unable to interpret signature of its halo but it is believed to be same as Andromeda's.

“Understanding huge halos of gas surrounding galaxies is immensely important. This reservoir of gas contains fuel for future star formation within galaxy, as well as outflows from events such as supervae. It’s full of clues regarding past and future evolution of galaxy, and we’re finally able to study it in great detail in our closest galactic neighbour, ” said co-investigator Samantha Berek.

Innner and outer shell 

As a part of landmark study, y also discovered that halo has a layered structure, with two main nested and distinct shells of gas. Explaining furr, study Leer Nicolas Lehner said that inner shell, which extended half a million light-years was more complex and dynamic. In contrast, outer shell, was comparatively smoor and hotter ding that difference was a “ likely result from impact of superva activity in galaxy’s disk more directly affecting inner halo.” team has also discovered a large number of heavy elements in gaseous halo. scientists have w predicted that both  halos of Andromeda and Milky Way were on a collision course indicating that both galaxies would merge to form a bigger elliptical galaxy, in upcoming four billion years.
