He built the first reflection telescope! He built the first reflection telescope!
Galileo was the first scientist to turn a telscope on the night sky and record his results. He had enough scientific training to understand the importance of what he saw. Galileo's discovery of the four moons orbiting Jupiter opened up the question of whether everything must orbit round the Earth. Then his discovery of the full range of Venus's phases indicated a definite fault with the Ptolemaic system. Galileo said that this must prove the correctness of the Copernican system. However the system that was eventually adopted was that of Kepler. It resembled the Copernican system with the Sun at the centre. Eventually Newton explained why the planets follow Kepler's laws through the operation of the force of gravity.
The four moons were discovered sometime between 1609 and 1610 when Galileo made improvements to his telescope, which enabled him to observe celestial bodies more distinctly than had ever been possible before. As a result of improvements Galileo Galilei made to the telescope, with a magnifying capability of 20×, he was able to see celestial bodies more distinctly than was ever possible before. This allowed Galilei to discover sometime between December 1609 and January 1610 what came to be known as the Galilean moons. :)

Why, the telescope, of course! Using his telescope, Galileo was able to make observations of the heavens in a way no one else was able to before.
Hijra is important in Islam as it marks the migration of the Prophet Muhammad from Mecca to Medina. It is considered a turning point in Islamic history, symbolizing the establishment of the first Islamic state. The Hijri calendar also begins with the year of the migration (622 CE), making it significant for Muslims worldwide.
