The constellation Ursa Major, also known as the Big Dipper, can be seen in the northern hemisphere of the sky. Its seven stars form a shape that resembles a ladle with a handle. The two brightest stars, Aliot and Dubhe, have an apparent sidereal magnitude of 1.8. By following the line from the two outermost…
Galaxies are enormous groups of stars, interstellar gas, and cosmic dust. Each one contains millions to trillions of stars. When you observe the most distant galaxies with a regular telescope, they appear as hazy luminous spots. There are three primary categories of galaxies in the Universe – elliptical-shaped galaxies, spiral galaxies, and irregularly shaped galaxies….
The measurement of the distance to the Earth’s center in kilometers is a parameter that is subject to interpretation, with scientists from different developed countries using slightly different approaches. Regrettably, humans have a limited understanding of the internal structure and rotational characteristics of our own planet compared to our knowledge of nearby celestial bodies. The…

Four decades ago, scientists from Earth launched two spacecraft on an ambitious journey, which were given the names Voyager 1 and Voyager 2. These spacecraft are essentially the same, with the only difference being their names and launch dates. Voyager-2 was sent off on August 20, 1977, while its counterpart was launched on September 5…
The commencement of a new astronomical season signifies the ideal time to behold novel celestial entities! This article is dedicated to deep-sky objects (DSO), commonly referred to as “dipsky” objects. We will enlighten you about galaxies and star clusters that are observable during the month of October. The selected dates in this article are chosen…
The starry sky was once used as a navigational tool for travelers. Ancient people created patterns out of the brightest stars and assigned them names based on Greek mythology, animals, and objects. As new stars were discovered, the boundaries of these constellations were adjusted. However, in 1935, astronomers made the decision to no longer revise…

At the core of the Solar System lies the magnificent Sun, which reigns as the largest entity. Boasting 99.8% of the solar system’s mass, it dwarfs the Earth with a diameter that is approximately 109 times greater – an astonishing fact that allows for a million Earths to be comfortably accommodated within its fiery embrace….
Take a moment to envision yourself standing in the heart of the Sahara Desert. The vast expanse of sand stretches out before you, extending as far as your eyes can see. To your right and left, there is nothing but sand. Even beneath your feet, the sand continues endlessly. This pattern repeats itself for hundreds…
In the late evening of May 17, 1990, a meteorite descended 20 km to the west of Sterlitamak. This extraterrestrial phenomenon caused quite a commotion, both literally and metaphorically. The main fragment, weighing 315 kg and composed of an alloy that is not naturally found on Earth, is now on display at the Ufa Museum…
Astronomical time refers to the measurement of time using celestial events and phenomena. It is a system that is based on the movements and positions of celestial bodies, such as the Sun, Moon, and stars. The concept of astronomical time has been used by various civilizations throughout history to determine the passage of time and…
By analyzing the anisotropy of microwave background radiation, scientists have been able to determine the speed at which the Sun is moving from the constellation Aquarius to the constellation Leo. This speed is estimated to be around 400 kilometers per second. This represents the Sun’s absolute motion speed within the vast expanse of the Universe,…
The question of determining the precise location of the core of our planet has captivated people worldwide for many centuries. It is no surprise that the renowned author Jules Verne dared to explore and write about the possibilities of reaching this enigmatic place. This endeavor may seem implausible due to the immense gravitational force that…
The concept of antimatter annihilation is frequently discussed by science fiction authors as an incredibly potent and seemingly limitless energy source. After all, a minuscule quantity of antimatter is capable of producing a tremendously powerful explosion. In this article, we will explore what antimatter is and delve into the reasons why scientists have not yet…
1. The dimness of the moon’s ash light is a result of the moon’s motion around the Earth and the Earth’s motion around the Sun, which determine the phases of the Moon. This information can be used to learn how to identify lunar phases and understand the conditions under which they occur. 2. The study…
During the 18th century, a scientific expedition was organized by the French government to explore the coasts of Latin America. The main goal of the participants was to conduct experiments and determine whether the earth is more similar to a flattened ellipsoid or an elongated shape. “Winterization is warm!” – the scientists exclaimed with joy….
Astronomical research focuses on the scientific exploration of celestial objects like stars, planets, comets, and galaxies. This field also encompasses the study of phenomena that occur outside of Earth’s atmosphere, such as cosmic background radiation. Astronomy is one of the oldest scientific disciplines and encompasses the study of evolution, physics, chemistry, meteorology, and the motion…
Atmosphere and climate The air, commonly known as the atmosphere, is the vital component that sustains life on our planet. Composed of a mixture of gases and possessing distinct characteristics and dimensions, the Earth’s atmosphere plays a crucial role in shaping our weather patterns and supporting diverse ecosystems. Let’s explore the composition and structure of…
The multitude of forces we experience in our daily lives can be classified into four main categories: gravity, electromagnetism, strong force, and weak force. Recently, scientists have uncovered potential indications of a fifth fundamental force of nature, as we previously discussed. Now, it is essential to delve into the mechanics of these fundamental forces. Explore…
