Outer Space

     If we gaze up at the sky with a telescope during a dark moonless night, we can see a hazy band of light shaped like a crescent. This hazy band is the light produced by some of distant stars from among the vast collection of stars. This wide collection of stars in the galaxy is called the milky way. The galaxy is much greater than what we can perceive from within it. We have yet to actually physically travel beyond the galaxy and view it from the outside. According to recordings made by astrophysicists, it contains about a 100,000 million stars. Besides the varieties of stars, such as red giants or white dwarfs, many other objects that often surpass our imagination fill our galaxy. The center of our galaxy is a gigantic abyss with a gravitational pull so strong that it even manages to trap light. This is the Black Hole.
