※ The number of galaxies is about one trillion.
※ The end of the universe is moving away from Earth at a rate of about 3.5 times the speed of light. (Which appears to be viewed from any galaxy, other galaxies are uniformly distributed, as moving away at a speed proportional to the distance)
Milky Way galaxy

※ The shape of the Milky Way galaxy is the disk about 100,000 light-years in diameter, and 15000 light-years in thickness.
※ In the Milky Way galaxy, there are about 200 billion〜400 billion stars.
