Video can be rephrased as Visual Content or Moving Images . The Autumn Sky’s Constellations During the autumn season, when the sky is often covered by clouds, stargazing can be challenging. However, there are several constellations that can still be observed, including Delphinus, Microscopium, and Capricornus. In the northern hemisphere, you can see constellations such…
Tungsten carbide is a tool used for drilling shallow holes ranging from 2 to 10 mm in diameter in soft wood. The tungsten carbide drill has a spiral cutting edge along its shaft. It has a fine screw thread at the end, which allows it to be screwed into the wood while rotating. However, tungsten…
It is common knowledge that the zodiacal constellation Pisces is situated in the night sky. Due to its position between Aries and Aquarius, it is often divided into its northern and western parts. The northern part is located beneath Andromeda, while the western part lies in the region between Pegasus and Aquarius. In actuality, these…
Equatorial coordinates refer to the specific set of coordinates used in astronomy to describe the position of luminaries in the sky or points on the celestial sphere. These coordinates are defined by two angular quantities, which uniquely determine the location of objects in the celestial sphere. Unlike other coordinate systems, the equatorial coordinate system is…
When you look up at the sky, you will find the constellation Libra positioned between Scorpio and Virgo. These constellations are part of the zodiacal circle. Libra also shares its celestial neighborhood with the Wolf, Hydra, Serpent, Centaurus, and the head of the Serpent.It is interesting to note that Libra is quite visible in the…
A 24-hour period (plural ancient form collision, junction meaning “the junction of day and night”) is a unit of temporal measurement, approximately equivalent to the duration of the Earth’s rotation around its axis. Typically, a day refers to the astronomical concept of a solar day. In everyday language, a day is often referred to as…
The Scorpio constellation can be found in the southern part of the sky and is a prominent feature of the zodiacal circle. While it may not be the largest constellation, it holds great significance. Ranking as the 33rd largest constellation by area, Scorpio is situated alongside other well-known constellations such as Libra, Sagittarius, and Wolf….
Science The Chelyabinsk meteorite that descended on Friday February 15, 2013 has raised numerous inquiries. Based on available information, a meteorite measuring approximately 15 meters in diameter and weighing 7,000 tons entered the Earth’s atmosphere at an inclination of roughly 20 degrees, traveling at a velocity of 65,000 km per hour. It traversed the atmosphere…
The Solar System consists of the Sun and a variety of celestial objects such as planets, meteorites, asteroids, and comets. These planets have different distances from the Sun, but they all orbit around it in unique paths. The Sun itself is much larger in mass compared to all other celestial bodies in the solar system…
One of the layers that make up the Earth’s atmosphere is the stratosphere, which makes up 20% of the overall air supply. The stratosphere is the second layer from the surface of the planet among the five main layers, measured in kilometers from the Earth. Location and Altitude Above Earth Situated between the underlying troposphere…
In the previous lesson, we discussed the vast number of galaxies present in the cosmos. However, what exactly is the cosmos? This inquiry has captivated countless generations of individuals. The cosmological theories that have emerged throughout the various stages of human civilization can be regarded as representations of the corresponding era’s understanding of the structure…
Within the field of photometry, illuminance refers to the overall amount of light that falls on a particular surface, divided by the surface area. It serves as a measurement of the extent to which incident light brightens a surface, taking into account a wavelength-weighted luminosity function that corresponds to an individual’s perception of brightness. In…
Objective: The aim of this lesson is to establish a comparison between the components of the Earth’s sphere and the celestial sphere, to enhance focus and communication skills, and to improve independent learning abilities. The goal is to develop the ability to utilize the horizontal coordinates of celestial bodies in solving qualitative problems. Download: Preview:…
Mercury is the first planet, Venus is the second planet, Earth is the third planet, and Mars is the fourth planet. Jupiter is the fifth planet, Saturn is the sixth planet, Uranus is the seventh planet, and Neptune is the eighth planet. Table of Contents: How many planets are there? How many planets are there…
The age of the Milky Way is estimated to be around 13 billion years. Some of the oldest stars in our galaxy were formed shortly after the birth of the Universe. Despite the vast amount of time that has passed, our civilization is the only one known to have reached a technologically advanced stage. Considering…
Astronomy, a crucial scientific discipline, explores the composition, movement, inception, and evolution of celestial entities. The primary goals of astronomy encompass: analyzing the positions and trajectories of celestial bodies in outer space, determining their dimensions and forms, investigating the physical structure of celestial entities. What is the definition of a Galaxy? A vast, independent assemblage…
A celestial coordinate system is utilized to determine the precise location of a celestial body. These systems, known as the ecliptic coordinate system or equatorial coordinate system, are constructed based on specific circles of the celestial sphere. In contrast, the geographic coordinate system is employed to determine coordinates on the Earth’s surface. Let’s explore each…
Planet Earth is a treasure trove of enigmas, with one of the most intriguing being the mystery of its innermost core. While human-made mines can only delve a few kilometers deep, the secrets residing deep within our planet remain inaccessible. Nevertheless, scientists have managed to piece together a rough sketch of its internal composition.
Planets are the largest objects in the Solar System, excluding the Sun. The definition of the term “planet” has been a subject of debate among astronomers for a considerable period of time. However, in 2006, the International Astronomical Union finally formulated a precise definition, which only applies to bodies within our solar system. According to…
In the distant future, it is highly probable that humanity, or a portion of it, will be required to depart from Earth. This necessity may arise due to factors such as overpopulation, natural disasters, or the depletion of natural resources. However, simply leaving our current home and venturing into space in search of a new…
