NASA scientists mapped them out Gas envelope around Andromeda, the galaxy closest to the Milky Way. You have found that the halos of both galaxies have collided. To conduct the study, they used NASA’s Hubble space telescope, one of the most advanced in the world.
Thanks to research, they have watched the Andromeda halo stretch more than a million light years from the galaxy towards the Milky Way and up to two million light years in other directions. It is the most comprehensive study to date of the gas envelope surrounding galaxies.
Samantha Berek of Yale University in New Haven, Connecticut explains the understanding of the Behavior of gas halos This is important around the galaxies in order to find out their evolution.
In this study, they found that the inner layer, which can extend up to half a million light years, has a larger one Complexity and dynamism than they believed until now. Meanwhile, the outer layer is warmer and softer.
Through the program AMIGA project (Ionized gas absorption map in Andromeda)The research has analyzed the light from a total of 43 quasars that are located beyond the Andromeda galaxy. Quasars are located behind the halo, making it easier for scientists to explore different regions.
He Andromeda Halo It consists of ionized gas that does not emit radiation. Therefore, the best way to study this material is to track the absorption of light from a background source.
