Its story

In the Great Bear, where the Plough tilts its handle toward the horizon, shines an orange K-type star, cooler than the Sun, with a serene ancient glow. Its light needs close to 449 years to reach us: what we see today departed about 1577, when a comet crossed the skies of Europe and Tycho Brahe proved it lay beyond the Moon, demolishing the notion of immutable celestial spheres.
