Our galaxy is called the Milky Way. You could compare it to one city in a vast network of cities. As the birthplace of humanity, home to billions of stars, there are so many mysteries surrounding our galaxy that scientists have yet to unravel. But over the centuries they have made numerous discoveries, revealing a little of the unbelievable and interesting facts about the Milky Way to the public, including the following:

Culture

  1. The Chinese have a legend about the gods creating a river in the heavens to keep a weaver and a herdsman apart. It is from this myth that the Chinese derive the term ‘The Silver River’, their name for the Milky Way.
  2. The Greeks used to call it the ‘Road to Mount Olympus’. They attributed the Milky Way to Hera who spilled her milk as she suckled Heracles.
  3. To the ancient Cherokees, a dog stole some cornmeal. When it was chased, the dog ran, spilling the cornmeal along the way, forming the Milky Way, hence The Way the Dog Ran Away, their name for it.

Milky Way History

  1. Where others saw magic or the work of the Gods, Democritus, a philosopher from ancient times (460–370 BC) saw the light in the sky and became the first person to suggest that the galaxy might consist of stars.
  2. In 1610, so many years later, Galileo used his telescope to cement Democritus’ claims by identifying the bands of light as a series of individual stars.
  3. The world’s understanding of the shape of the Milky Way can be attributed to Edwin Hubble who, in the 1920s, discovered a way of using the brightness of stars to measure the distance between galaxies.

Science

  1. The Milky Way, which is 120,000 light-years across, is a disk but it is warped. It isn’t perfectly flat. This warping is the result of two dwarf galaxies that are pulling on the Milky Way.
  2. There are no pictures of the Milky Way. Any images you have seen are an artistic impression or another galaxy. From the Earth’s position, there is no way to take a picture of the disk that is the Milky Way.
  3. Anyone who looks at the Milky Way from the Earth with the naked eye can only see and count 2,500 stars. But the number is closer to 400 billion.
