The Science of Reading the Stars
A Science Written in the Sky
Long before the invention of GPS or compasses, Polynesian navigators sailed vast distances across the Pacific Ocean. Their primary tool was an incredibly deep understanding of the stars, sun, moon, and ocean currents. This was not luck; it was a precise science passed down through generations. In Aotearoa, this knowledge, known as **kōrero whetū** or **tātai arorangi**, was essential for navigation, timing planting and harvesting, and for cultural identity.
Key Stars and Constellations
Matariki (The Pleiades)
Indicator of: The Māori New Year
The pre-dawn rising of the Matariki star cluster in mid-winter marks the beginning of the Māori New Year. Its brightness and the clarity of each star were used to predict the success of the coming season. A clear, bright Matariki signalled a warm and productive year ahead.
Tautoru (Orion's Belt)
Indicator of: The "Tuna" or Eel Season
When Tautoru, the three bright stars of Orion's Belt, is seen rising in the east, it signals the time when the tuna (eels) begin their migration. This was a crucial time for harvesting this important food source.
Te Pae Māhutonga (The Southern Cross)
Indicator of: South
This is perhaps the most famous navigating constellation in the Southern Hemisphere. By identifying Te Pae Māhutonga, navigators could reliably find the direction of south, allowing them to orient their waka (canoe) on the open ocean.
Rehua (Antares)
Indicator of: The Height of Summer
Rehua is one of the brightest stars in the sky. Its appearance high in the summer sky was associated with the hottest months and the time when certain fruits and berries were ripe for picking.
The Star Compass: A Mental Map
Māori navigators did not use a physical compass. Instead, they used a mental model called a **star compass**. They memorised the rising and setting points of over 200 stars on the horizon. By knowing the sequence of stars that would rise and set throughout the night, they could hold a steady course. This was combined with knowledge of ocean swells, wind patterns, and the flight of birds to create a sophisticated and reliable navigation system.
Critical Thinking Questions
1. How is the Māori practice of using Matariki to predict the coming season a form of scientific forecasting?
2. The star compass is a "mental model". Why would it be important for every navigator on a waka to have the same mental model?
3. (Extension) Go outside on a clear night. Can you identify any of the stars or constellations mentioned in this handout? What direction are you facing?
