Some human cells magnified 10 million times |
Milky Way Galaxy |
The Milky Way is a barred spiral galaxy 100,000–120,000
light-years in diameter containing 200–400 billion stars. The human body …
consists of an estimated 20 to 30 trillion cells. This means there are
approximately 75 times more cells in a human body than stars in the Milky Way
galaxy. Amazing!
