Are all the 88 constellations in the Milky Way? What about the usual 12 constellation?

Because there are many stars in the sky, most of them are stars (basically invisible in the sky), and there are about 6,000 stars that can be seen by the naked eye. The vast Xinghai often makes many people sigh, and they don't know how to recognize the stars. In fact, we must first understand how the star region is divided. Just like knowing your best friend, you should know his home address and the environmental characteristics around his home. The division of stellar sky region is equivalent to the division of blocks. In ancient China, the starry sky was divided into three walls and twenty-eight houses. Accommodation is living. Divide the stars outside the accommodation into three walls: Wei Zi wall, Taiwei wall and Shi Tian wall. Wall means wall. It means an area of stars surrounded by walls.

The ancient Babylonians divided the sky into many regions called "constellations", and each constellation was identified by the special distribution of bright stars. The ancient Greeks divided the visible part of the sky into 48 constellations around 270 BC, connected the main bright stars in the constellations with imaginary lines, imagined them as people or animals, and gave them appropriate names in combination with fairy tales. This is the origin of the constellation name. 1928, the international astronomical union decided to divide the whole day into 88 star regions, called constellations. Among these 88 constellations, there are 12 constellations along the ecliptic. They are Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn and Aquarius. There are 29 constellations in the north and 47 constellations in the south.

Because there are more than forty constellations in Greek mythology living in the northern sky and north and south of the equator, they are just our common constellations. As long as you remember the positions and names of these constellations and their relationships with other constellations around you, and remember the imaginary pictures connecting the main bright stars, you can easily identify the whole starry sky.
