Galaxies on Instagram: "The James Webb Telescope follows the L2 point, or second Lagrange point, a spot about 1.5 million kilometers from Earth, on the opposite side from the Sun, where the gravitational forces of the Sun and Earth balance. This allows spacecraft like the James Webb Space Telescope to maintain a stable position with minimal fuel. L2 provides a cold environment, shielded from heat, ideal for infrared observations, and an unobstructed view of deep space. However, its distance make

Galaxies on Instagram: "In a vacuum, all objects, regardless of their mass, fall at the same speed due to the absence of air resistance. This phenomenon is explained by Galileo’s principle of equivalence, which states that the acceleration due to gravity is the same for all objects. Hence, a bowling ball and a feather will fall at the same rate in a vacuum. On planets with no atmosphere, such as Mercury, the same principle applies. Without atmospheric drag, the bowling ball and the feather exper
