Beacons in the Night: Understanding Constellations and Stellar Giants
For thousands of years, humans have looked toward the night sky and seen more than just scattered points of light. Our ancestors perceived shapes, heroes, and creatures in the darkness, creating a celestial map that helped them navigate the seas and track the changing seasons. These patterns, which we call constellations, are essentially a human-made filing system for the universe. Today, astronomers recognize 88 official constellations that divide the entire sky into specific regions. However, what looks like a flat picture from our perspective on Earth is actually a vast, three-dimensional arrangement of stars that are often separated by hundreds of light-years of empty space.
