During the summer months, the night sky presents a mesmerizing display of stars. However, there are certain celestial formations that are best observed during the colder season. One such enchanting constellation is Orion. With a grand total of 209 stars that are visible to the naked eye, Orion stands out due to its abundant collection…
Seismic events, similar to earthquakes, can also occur on stars. However, these events are not visible to us in their entirety due to their distance. Nevertheless, we can make an estimation based on the fluctuations in the brightness of the star. By studying the propagation of elastic waves within a star, we can gain knowledge…
Orienteering using the North Star, Polaris, is the most well-known method of orienteering in the Northern Hemisphere. Polaris is the star closest to the Earth’s axis of rotation among all the stars visible to the naked eye, and its position in the night sky changes slightly compared to other celestial bodies. Because of its proximity…
When I was a child, time seemed to move at a glacial pace. I remember fantasizing about ice skating during the summer and swimming in the river during the never-ending winter. As I got older, I realized that our vast planet experiences different seasons throughout the year. We have harsh winters and scorching summers, pleasant…
Ursa Minor is the name of a constellation situated in the northern sky, which translates from Latin as “lesser bear”. The constellation known as the Little Bear first appeared in the sky during the second century, thanks to the work of Ptolemy. It can be easily identified by its famous asterism or its position near…
Andromeda is located far away from Earth. It is estimated to be approximately 2.537 million light-years away from us. This means that it would take light, which travels at a speed of about 299,792 kilometers per second, more than 2.5 million years to reach us from Andromeda. The Sun, on the other hand, is much…
The star called the Sun is the center of a vast collection of planets known as the solar system. These planets, along with their moons, asteroids, comets, and numerous meteoric elements, orbit around the Sun, which is significantly larger and heavier than them. The star at the center of our solar system is called the…
The Earth’s crust finished forming about 3.8 billion years ago, marking the origin of life on Earth. Scientists have discovered that the first living organisms emerged in aquatic environments, and it took another billion years for the first creatures to venture onto land. The development of terrestrial flora was aided by the evolution of plant…
In the early 17th century, Galileo revolutionized the study of astronomy by enhancing the existing telescope and directing it towards the sky. It was one of Galileo’s acquaintances who coined the term telescope, which signifies “far-seeing.” Illustration 160. Page from the manuscript of Galileo documenting his observations of the moons of Jupiter In the early…
The universe is a vast expanse, stretching across billions of light-years, and the majority of this space is empty. However, within this vastness, there are numerous colossal celestial bodies known as galaxies, each containing billions of stars. Among these galaxies is our very own Milky Way, which is quite sizable. But, when it comes to…
Once known as the ninth planet in our Solar System, Pluto derived its name from the Roman god of the underworld. However, in 2006, astronomers reclassified Pluto, sparking curiosity about its actual status in our cosmic neighborhood. The Discovery Story Back in 1930, American astronomer Clyde William Tombaugh made a groundbreaking find at the Arizona…
The structure of the solar system is planetary in nature, consisting of a main star known as the Sun, as well as eight other planets. Almost every planet within the solar system has its own satellite, which can be described as a small celestial body. Understanding Satellites Before providing a precise definition, it is important…
"If you haven’t yet familiarized yourself with the Big Dipper constellation, the night sky will forever appear as a jumble of twinkling lights. " "Currently, astronomy is not a mandatory subject in schools and is instead offered as an elective." Figure 1 shows a diagram of the constellation of the Big Dipper. Ursa Major, also…
Around 80,000 years ago, a band of young Homo sapiens embarked on a historic journey beyond Africa. Since then, the quest for new realms has persisted. The descendants of these intrepid adventurers meticulously charted the Earth, set foot on the Moon, and marveled at the vastness of the Universe. But before these momentous achievements, they…
In the realm of the night sky, celestial bodies may bear a striking resemblance to one another, but upon closer inspection, their unique attributes become apparent. Variances in distance between an observer on Earth and the celestial bodies contribute to disparities in luminosity. There are moments in life when the urge to recline beneath the…
When it comes to faraway celestial entities, those not well-versed in the field of astronomy often wonder: how do astronomers, astrophysicists, and cosmologists ascertain the distance to the object being studied and how do they go about determining it? In this article, I will delve into the methods employed by astronomers to measure distances to…
Arcturus, which is both bright and beautiful, is known as the guardian of the Big and Little Dipper! This star, with its red or orange color, is believed to have originated from a distant galaxy that collided with the Milky Way during its journey! Arcturus is the brightest star in the Volopassus constellation and the…
Not many are aware, but it was the Big Dog constellation that introduced the term “vacation” into our vocabulary. The reason being that Sirius, the most brilliant star in this constellation and in the entire northern hemisphere, becomes visible in the early morning just before the summer solstice. In ancient Egypt, this occurrence signified the…
Earth is a celestial body that is in constant motion within the universe. It undergoes rotation on its axis and travels millions of kilometers in its orbit around the Sun. Along with the entire planetary system, it slowly orbits around the center of the Milky Way galaxy. The Earth’s rotation and orbit around the Sun…
On a certain planet, bodies at the equator have half the weight compared to the poles. The density of the planet’s substance is 3000 kg/m3. Calculate the rotation period of the planet around its own axis. Problem № 2.5.16 from “Collection of problems for preparation for entrance exams in physics UGNTU” Given: Solving the problem:…
