Observatory telescopes today are virtual behemoths compared to Galileo´s 1 3/4-inch-diameter (4.4 cm) models. His primitive devices were refracting telescopes. A large convex lens on one end formed the image and a small concave lens at the other end, later modified to be also convex, magnified the image. Remarkably, his instrument could magnify objects up to 33 times, allowing him to view such distant wonders as Jupiter´s four moons and Venus´ moon-shaped phases.
Today´s reflecting telescopes use immense, bowl-shaped mirrors (up to 236 inches [600 cm] across!) to collect light from faraway heavenly bodies. Therefore they can detect objects ten million times fainter than those which can be seen with the naked eye. Why, it is claimed that one telescope in Australia could detect a candle flame a thousand miles (1,600 km) away! Interestingly, though, astronomers today still run into the same problem Galileo faced. The stars increased in number but not in size he noticed. Galileo reckoned that the stars must be incredibly distant to remain mere points of light under magnification…
