[3] Galileo has been called the “father of observational astronomy “, [4] the “father of modern physics”, [5] [6] the “father of the scientific method “, [7] and the “father of modern science “. [8] Galileo studied speed and velocity , gravity and free fall , the principle of relativity , inertia , projectile motion and also worked in applied science and technology, describing the properties of pendulums and “ hydrostatic balances”. He invented the thermoscope and various military compasses , and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus , observation of the four larges...

They consist of countless small particles, ranging in size from micrometers to meters , [1] that orbit around Saturn . The ring particles are made almost entirely of water ice, with a trace component of rocky material . There is still no consensus as to their mechanism of formation. Although theoretical models indicated that the rings were likely to have formed early in the Solar System’s history, [2] new data from Cassini suggest they formed relatively late. [3] Although reflection from the rings increases Saturn’s brightness , they are not visible from Earth with unaided vision . In 1610, the year after Galileo Galilei turned a telescope to the sky, he became the first person to observe Saturn’s rings, though he could not see them well enough to discern their true nature. In 1655, Chri...
