Chasing Shadows: The Science and History of Solar Eclipses
Few astronomical events capture the public imagination as intensely as a solar eclipse. When the Moon’s shadow sweeps across the face of the Earth, day turns to night, temperature drops, and the Sun’s corona—a pearly aura usually hidden by the Sun’s glare—becomes visible. But what exactly is a solar eclipse, why do they occur, and…

The Evolution of Ground-Based Observatories: From Galileo to the Thirty Meter Telescope
Observatories have long stood as the sentinels of astronomical discovery, translating the faintest whispers of the cosmos into revelations about our universe. Since Galileo Galilei first pointed his small refracting telescope skyward in 1609, ground-based observatories have undergone a remarkable evolution, fueled by technological innovation and scientific curiosity. The earliest observatories, such as the Royal…
