※ Radius of the observable universe is about 45 billion light-years. ( The theoretical value calculated from redshift.)
Space beyond that area, does not know whether infinite or finite.
※ 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 Disk of the Milky Way 
※ 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.
