Happy 400th, telescope!
400 years ago today, Italian scientist Galileo Galilei unveiled his first eight-powered telescope to the merchants of Venice. A refinement of earlier, lower-powered telescopes, this instrument enabled him to confirm the phases of Venus, discover the moons of Jupiter, and observe sunspots.
