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…
Andromeda is a celestial formation consisting of a group of stellar systems, interstellar matter, and gas that are influenced by gravitational forces. It is located at a distance of 2.5 million light-years from the Earth and is the sole celestial object visible to the unaided eye that is not part of the Milky Way. The…

It is crucial to follow the warning on your telescope that says, “Never point the telescope at the Sun!” This warning is usually in the form of a bright sticker or label on the tube. However, with proper preparation, you can safely observe the Sun using your telescope. This article will guide you through the…
A star cluster is a group of stars that are bound together by gravity and have a shared origin. These clusters move through the galaxy as a single unit, influenced by the gravitational field. Some star clusters also contain clouds of gas and/or dust. Star clusters can be classified into two main types based on…
Dawn is the time at which twilight begins before sunrise. In the late summer, dawn breaks over the Mojave Desert in California. Dawn can refer to the start of morning twilight, the period of twilight, or the time of sunrise. At dawn, the horizontal skyline of Kaohsiung, Taiwan is visible. The skyline of Prague is…
There is limited knowledge among the general population about the effects of different levels of G-force, such as 1G, 2G, 5G, 8G, and 10G, unless they are involved in civil or military aviation. It is commonly understood that passengers on a commercial aircraft experience inertial forces equivalent to approximately 1.5 G during takeoff. As the…
The concept of what lies beyond the edge of the universe has intrigued both scientists and the general public who have a fascination with the enigmas of the cosmos. The portion of the celestial sphere that is observable to us during the night is merely a fraction of the vast expanse of cosmic space. The…
The constellation known as Orion’s belt is comprised of a trio of stars that align to form a distinctive geometric shape resembling a belt. These stars, named Alnitak, Alnilam, and Mintaka, are located in the central region of the Orion constellation, which takes the form of a mythical hunter. In Greek mythology, this arrangement is…
Science We have all been aware since our early years that the Sun is situated at the core of our solar system, with the four closest planets to Earth – Mercury, Venus, Earth, and Mars – revolving around it. Subsequently, we have the four gas giant planets: Jupiter, Saturn, Uranus, and Neptune. Since Pluto was…
The question of how many galaxies there are in the universe is a complex one. Historically, astronomers have made attempts to determine the total number of galaxies in existence. However, counting them has proven to be a daunting task. As the numbers reach into the billions, the process becomes time-consuming. Additionally, the limited capabilities of…
Io, one of Jupiter’s moons, is named after Zeus’ mistress and is a fascinating and perilous celestial body that could easily be described as a version of hell. Io is part of the Galilean moons, a group of four satellites that are each distinct and offer unique worlds that can captivate even the most imaginative…
Astrometry serves as the foundation for astronomical observations and the measurement of coordinates and time. The primary objective of astrometry is to establish a reference frame, which corresponds to the inertial reference frame described in Newton’s first law. Throughout history, astronomers have compiled star catalogs to achieve this goal. These catalogs have enabled the discovery…
The origins of astronomy can be traced back to ancient times, making it one of the oldest scientific disciplines. An important practical aspect of this field of study was its ability to assist with navigation and orientation. Astronomy and astrology As far back as the Middle Ages and Ancient Egypt around 4 thousand BC, people…
It is commonly believed that the Earth’s core lies at a depth ranging from 6,000 to 6,400 kilometers beneath the Earth’s crust. The core, which constitutes the innermost part of the Earth, is composed of iron, nickel, and sulfur. The Earth’s crust, on the other hand, forms the outer layer of the planet and primarily…
Despite its close proximity to Earth, the moon has a completely distinct appearance from our planet. Its surface is markedly dissimilar to that of Earth. What is the composition and surface of the Moon? The Moon is similar in structure to Earth and is composed of several layers: An inner core made up of molten…
A simple method to navigate the stars is by locating Polaris. It is not only one of the brightest, but also remains stationary in its position. There are two well-known techniques that can be used to accurately locate Polaris. The constellation of Ursa Major and Ursa Minor These star formations are depicted as a large…
The Earth has an average weight of approximately 5.976 sextillion tons, a staggering number with 21 decimal places. Just visualizing such a figure can be overwhelming due to the multitude of zeros involved! However, determining the mass of our planet is far from a simple task, unlike weighing a watermelon. We cannot simply place the…
