KOMPAS.com – Being one of the phenomena that is considered an interesting and not to be missed sky view, the sash galaxy Bima sakti can be witnessed from Earth at dawn.
The Milky Way is one of the largest galaxies in the disk-shaped universe and is a collection of billions of stars in this universe.
Marufin Sudibyo, Advisor and Assistant to the Gombong Phantom Science Study Forum (FKIK) and the Kebumen Research Institute for Falak Science (MKIF) in Central Java, Marufin Sudibyo, said that the Sun and the entire solar system are located on the edge of the Milky Way.
These conditions make it possible to view most of the structure of these galaxies.

“Called the milky way sash because it is shaped like a fine scarf that stretches from north to south with a certain motif on the parts, “said Marufin to Kompas.com, Saturday (1/5/2021).
How did the Milky Way galaxy sash formed?
The Milky Way sash is part of the Milky Way galaxy that can be seen from our Earth (which is located at the edge of the galaxy).
According to Marufin, the process of forming the Milky Way galaxy itself follows the general mechanism of galaxy formation in our universe.
After the universe expanded through the Big Bang event to give birth to light atomic nuclei such as hydrogen and helium, along with electrons and other particles.
At that time there were higher dots of density which later developed into the nursery for the first generation of stars.
“These stars made up the ancient Milky Way galaxy,” he said.
These stars, most of which make up the Milky Way galaxy, are visible from the edges of the galaxy. Galaxy it contains about 100 to 400 billion stars.
Over time, the Milky Way absorbs material from other galaxies that pass by, whether it is forced to merge or not. So that the size continues to grow until it is witnessed at this time.
Lessons and the influence of the Milky Way galaxy on the Earth
“The study of the Milky Way’s galactic sash is fundamentally the same as understanding from studying galaxies in general as part of the large-scale structure of the universe,” he explained.
Galaxies are made up of stars. They generally cluster as star clusters (clusters), both regular and irregular.
Galaxies also contain non-stellar matter ranging from planets to interstellar dust.

The center of the Milky Way galaxy should be in the middle of this sash, but we cannot see it because of a similar population of interstellar dust blocking our field of view directly to the galactic center.
In addition, the Milky Way galaxy is also composed of dark matter, whose identity has not been much revealed and is still being actively studied.
Regarding the influence of the Milky Way’s sash on Earth, said Marufin, because we live in the Milky Way Galaxy, any changes in this part of the galaxy will affect the solar system and especially our Earth.
So far, however, no dramatic changes have been detected that could have an effect.
