Unraveling the Mystery: Why is it Called the Milky Way?

Our magnificent celestial home, the Milky Way Galaxy, harbors secrets that have intrigued humans throughout history. This galaxy’s name is a poetic testament to its stunning appearance. So let’s delve into the intriguing origins of the name “Milky Way”.

The Ancient Roman Mythology

The story begins in ancient Rome. The Milky Way is derived from the Latin term “Via Lactea”, directly translating to “the road of milk”. The romantic aspect of the universe was captured in the imagination of ancient Romans, who developed a myth behind the name.

Here’s a quick look at the Roman mythology that feeds the name:

• Jupiter, the king of gods, once fed his mortal son, Hercules, with his divine wife’s milk while she was asleep.
• The goddess, Juno, startled awake, and her milk spilled across the heavens.
• This spilled milk, forming a milky circle of light, was believed to be our galaxy.

The Ancient Greek Connection

The ancient Greeks also played a part in our galaxy’s name. The Greek term “Galaxias Kyklos”, meaning “milky circle” or “milky way”, is another origin of the name. The Greeks too had a similar myth where the milk of the goddess Hera splashed across the sky forming a milky pathway.
