The shape of the Milky Way galaxy, which follows our solar system, and how it appears in space, is what we will learn about in this topic, to learn more about our large galaxy, which consists of a large number of stars, atomic dust, and various celestial bodies, and provides the opportunity to refer to it Through this article to get a complete definition. On the shape of a galaxy and its characteristics, the most important information about it will be known, about the number of stars and many other information.
The Milky Way galaxy
The galaxy that includes our solar system in which we live, and includes a large number of stars similar to the sun, the number of stars in it reaches between 200 and 400 billion stars, which explains its large size, which is estimated at about 160 thousand light years. 27000 light years, and parts can be seen From the Milky Way with our naked eyes on clear nights, especially in late autumn days, as it appears in its beautiful form in the clear sky.
The shape of the Milky Way
The Milky Way takes the form of a thin circular spiral, and it is from the Milky Way of medium and small size, according to scientists, and it appears in the sky of our earth in the form of scattered bright stars and includes billions of planets in addition to our planets.
The solution belongs to the group of celestial bodies of the Milky Way galaxy
The arrangement of the solar system or the solar system that follows our planet to the Milky Way galaxy, where the sun is a medium-sized star among the constellations of the Milky Way galaxy, and the galaxy includes a large number of other stars in addition to the sun, and also includes a large group of planets up They number about 40 billion planets, and it is believed that many planets are similar to our planet Earth, and some scientists believe that there are other planets suitable for human existence.
Parts of the Milky Way
It consists of the main sections of the Sunnah, which are as follows:
- The nucleus: There is a large black hole in the center of the galaxy, surrounded by a large disk of high-temperature gas, and the nucleus cannot be seen due to the thick atomic dust surrounding it.
- The central bulge: It is a bulge composed of stars of the second group, which are heavy stars rich in elements. The bulge takes a spherical shape that directly surrounds the nucleus.
- The disk: It is the youngest part of the galaxy, and it takes the form of a spiral that extends from the galactic nucleus to a distance of 75,000 light-years, and spreads around the nebula.
- Spiral Arms: Also called spiral arms, which give the galaxy a spiral shape, and those arms or that spiral structure were not discovered until 1953, and these arms could not be detected visually because of the large scattering of mysterious dust and because of the inner part. location of our solar system.
- Center: the space surrounding the disk from above and below, and takes a semi-spherical shape, and a small part of the central bulge enters the center, and some stars of the second extreme group, and many outer stars, spread with it. spherical clusters.
- The massive halo: It is the most mysterious component of the galaxy, and it is known only through its influence on the curve of the outer orbit of the galaxy, which is far from the visible distance from the Milky Way, and extends the distance of this halo. At a distance of 100,000 light-years from the galactic center.
What are the types of galaxies?
There are different types of meteorites in the universe in terms of shape, according to their diversity between regular or irregular meteors, and therefore meteorites are divided into three types, namely:
- Spiral galaxy: It is characterized by its three parts: the center, the nucleus, and the halo.
- Al-Hajji galaxies: they are characterized by their elliptical shape, but without a specific axis of rotation.
- Irregular galaxies: They are mostly made of dust, which prevents the scattering of starlight.
Here is the end of the article that explains the shape of the Milky Way galaxy, after explaining the spiral shape of the galaxy, as well as the shape of its appearance in the sky of planet Earth, as well as the number of stars. Horoscopes and a lot of information about them.
