What are constellations?

Constellations are groups of stars that form recognizable patterns in the sky. There are 88 constellations recognized by the International Astronomical Union, each with its own name and story. Some constellations are easy to spot, like Orion with its distinctive belt of three bright stars, while others are more subtle.

How were constellations named?

Many constellations were named by ancient cultures, like the Greeks and Romans, who assigned mythological stories and characters to the stars. For example, the constellation Ursa Major, or the Big Dipper, was seen as a great bear by many cultures, including the Greeks and Native Americans. Others were named more recently, based on scientific discoveries and inventions.

How do constellations help us navigate?

Before GPS and maps, people relied on the stars to navigate. By studying the placement and movement of constellations in the sky, sailors and travelers could determine their location and direction. Today, while we don't use constellations for navigation as much, they are still used in astronomy to study the properties and movements of stars and galaxies.


Even though we have advanced technology and maps, looking up at the night sky and spotting constellations can still be a magical and awe-inspiring experience. Whether you're interested in navigation or just want to tell stories about the stars, take some time to look up and appreciate the beauty of the constellations.
