28. The largest known star in the universe is UY Scuti, which is about 1,700 times larger than the sun.

29. The Earth’s magnetic field is generated by the movement of molten iron in the outer core, creating a protective shield that deflects harmful solar radiation.

30. The concept of plate tectonics explains how the Earth’s crust is divided into several large plates that float on the semi-fluid mantle below, causing continents to drift and collide over millions of years.

31. The speed of sound in air is approximately 343 meters per second at room temperature.

32. The human body produces about 300 billion new cells every day to replace old or damaged cells.

33. The average cloud weighs about 1.1 million pounds, with larger clouds containing even more water vapor.

34. The planet Jupiter has 79 known moons, with the four largest moons (Io, Europa, Ganymede, and Callisto) known as the Galilean moons.

35. The human heart pumps about 2,000 gallons of blood through the body every day.

36. The Earth’s rotation is gradually slowing down at a rate of about 17 milliseconds per century, causing days to become slightly longer over time.

37. The tallest mountain in the solar system is Olympus Mons on Mars, which is about 13.6 miles high.
