Earth formed approximately 4.5 billion years ago from the solar nebula, a rotating cloud of gas and dust. Due to gravity, particles agglomerated to form...
The law of universal gravitation, formulated by Sir Isaac Newton in the 17th century, is one of the fundamental pillars of modern physics. This law...
The Earth rotates around its axis in about 24 hours, causing the cycle of day and night. This rotation is responsible for the change of...
At the heart of the stars, a constant nuclear reaction takes place, mainly the thermonuclear fusion of hydrogen into helium. This fusion process releases a...
When we observe the Moon on the horizon, it often appears larger than it actually is. This phenomenon, known as lunar illusion, is a deceptive...
Comets are celestial objects mainly composed of ice, dust, and rock. They are often described as primordial remnants of the solar system, dating back to...
The stars twinkle at night due to the interaction of starlight with the Earth's atmosphere. This optical phenomenon is caused by atmospheric turbulence acting as...
The rotation of the Earth around its own axis is the first reason why the Sun appears to rise in the east. This rotational movement...
Gravity is an attractive force that exists between two massive objects due to their mass. It is described by the law of universal gravitation stated...
Galileo was condemned by the Inquisition primarily because of the incompatibility of his astronomical discoveries with religious dogma. His observations challenged the widely accepted idea...
