Galileo Galilei made significant contributions to astronomy largely by improving which existing optical instrument and applying it to observe the night sky?

Explanation

Galileo Galilei made significant and influential contributions to astronomy in the early seventeenth century by substantially improving the design of the telescope, an instrument that had only recently been invented, and then applying it to make groundbreaking observations of the night sky, including detailed observations of the moon’s surface, the phases of Venus, and the four largest moons orbiting Jupiter. These observations provided important supporting evidence for the then-controversial idea that Earth was not the fixed center of the universe. Galileo’s astronomical work, though influential, also famously brought him into significant conflict with prevailing religious and scientific authorities of his time.
