The name for our galaxy comes from the ancient Greek words for ‘milk’ or ‘milky’. They could only see it as a bright band of light in the night sky.

The term 'Milky Way' originates from the ancient Greek word 'galaxias', derived from 'gala' and 'galaktos', meaning milk or milky. Early Greek mythology explained the appearance of the bright band in the night sky as milk spilled by the goddess Hera. 

Centuries later, philosophers like Democritus suggested the band was made of countless tiny particles, which we now know are stars. The invention of the telescope in the early 17th century allowed Galileo Galilei to observe and confirm that the Milky Way is composed of innumerable stars. Today, astronomers recognize the Milky Way as one of about a trillion galaxies in the observable universe, but it remains unique in name and mythological significance.

Why is our home galaxy called the Milky Way?

Why is our home galaxy called the Milky Way? The roots of the name can be found in the word galaxias, which comes from ancient Greek. It's derived from the terms gala and galaktos, which mean milk or milky. In those days of little light pollution, our home galaxy was visible everywhere as a bright band in the night sky. There were no telescopes. The ancient Greeks explained the origin of this milky road with a story. According to myth, the milk poured into the sky from the breast of the goddess Hera when she pushed one of her husband's illegitimate sons away as he sought to suckle. Over 2,500 years ago, the Greek philosopher Democritus came up with another explanation. The world is made up of tiny particles, he said, so the band of light in the sky must also consist of particles, which we call stars. Hundreds of years would pass before people could actually see individual stars in the Milky Way. Then, in the early 17th century, Dutch spectacle maker Hans Lippehey made a groundbreaking discovery, that distant objects appear larger when viewed through two ground lenses, laying the groundwork for the invention of the telescope. Galileo Galilei developed the instrument further and was the first to use it to observe the night sky. There he saw that the Milky Way really is made up of countless stars. Since the dawn of the 20th century, astronomers have been looking deeper and deeper into the universe. Bright dots that their predecessors saw in earlier ages turned out to be distant galaxies. Our cosmic home is just one of around a trillion aggregations of stars that are thought to populate the visible universe. But it's the only one called the Milky Way, a mythical name from the ancient world.
