The lithosphere, which is composed of the upper part of the mantle and the Earth’s crust, serves as the solid shell of planet Earth. Comprising stable platforms and moving fold belts, the lithosphere provides complete coverage over the Earth’s surface, shielding it from the extreme temperatures emanating from the radiant Earth’s core. While the thickness…
With a history spanning 4,000 years, the Eastern horoscope has become immensely popular worldwide. Its fundamental concept is to divide time into 12 annual cycles, each represented by a specific animal. These zodiac signs are associated with a unique set of qualities that are believed to influence a person’s destiny based on their date of…
Undoubtedly, you may have observed in the autumn sky, in its eastern region, a group of four stars creating a relatively large rectangle. This is known as the Pegasus constellation, or more specifically, its most prominent stars. Due to its distinctive shape, referred to as the Great Square of Pegasus, locating it in the sky…
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…
Uranus, the seventh planet in our solar system, is the third gas giant, following Jupiter and Saturn, and it is also the third largest planet. In terms of mass, Uranus ranks fourth. While Uranus is not the farthest planet from the Sun (Neptune holds that title), it is the coldest planet. This characteristic places Uranus,…
The solar system is home to a multitude of celestial bodies with varying sizes and shapes. Within this vast expanse, natural satellites hold a special place. Our very own Moon falls into this category as a satellite. Notably, the Moon stands out due to its impressive size. In fact, it is relatively large when compared…
A supernova is essentially an explosion of a star and is the most powerful event that can be witnessed in outer space. Where do supernova remnants appear? Supernovae are often visible in other galaxies. However, in our own Milky Way, it is a rare occurrence to witness a supernova due to the obstruction caused by…
As you are aware, stars have extremely high internal temperatures. It is this high temperature that initiates thermonuclear reactions. When a molecular cloud undergoes compression due to gravitational forces, it undergoes heating, which increases as the mass of molecules becomes sufficient. This leads to the synthesis of helium from hydrogen, or in simpler terms, the…
Relic radiation (or cosmic microwave background radiation) [1] – cosmic electromagnetic radiation that exhibits high isotropy and possesses a spectrum that is characteristic of a perfect black body with a temperature of 2.725 K. The prediction of relic radiation was a theoretical part of the Big Bang theory. While various aspects of the original Big…
While stars can vary in their physical characteristics, there are certain limitations to what is possible. Not every star that can be imagined by humans can actually exist. Stars are cosmic bodies that can only possess a certain amount of mass within certain limits. If the mass of a celestial body is less than 0.02…
Until recently, the UY Shield star held the title for being the largest star ever discovered. When compared to our Sun, our own star appears minuscule in comparison to the immense size of UY Shield. However, there exists a star even larger than UY Shield. In this article, we will explore the largest star known…
The position of luminaries in the sky or points on an imaginary celestial sphere is described using celestial coordinate systems in astronomy. The horizontal coordinates, also known as azimuth and altitude, are the angular quantities that define the position of objects on the celestial sphere. These spherical coordinate systems do not consider distance and vary…
How to locate the Andromeda galaxy in the starry heavens In our recent publication, we discussed how the Andromeda galaxy, along with the Small and Large Magellanic Clouds, is one of the few galaxies that can be observed without the assistance of a telescope. Moreover, the Andromeda Galaxy holds the distinction of being the farthest…
Ceres, which has been a topic of debate among astronomers, is a dwarf planet. It was first detected at an observatory in Italy in 1801. The name of this celestial entity was given in tribute to the goddess of agriculture and fertility in ancient Rome. General information After being discovered, the celestial body known as…
Polaris (Alpha Minor, α UMi) is the brightest star with a magnitude of +2.0 in the Little Bear constellation, which is situated near the North Pole of the Earth. Polaris is a supergiant and can be found at a distance of 447 ± 1.6 light-years (137.14 parsecs)[1][2]. Polaris, also known as the North Star, is…
Jupiter is not just the biggest planet in our solar system, it is also one of the most enigmatic. With a size 317 times that of Earth and 2.7 times greater than all the other planets combined, Jupiter boasts a ring system and numerous moons. Engagement Bands The rings of Jupiter were initially discovered by…
Cosmos Jupiter, the fifth planet from the Sun, is a gas giant and the largest object in our solar system. It is a subject of great interest for astronomers, who frequently send probes to collect data about this celestial body. Over the years, significant research has been conducted, allowing us to form a comprehensive understanding…
The Andromeda galaxy was first mentioned as a recognizable hazy object in 946 by the Persian astronomer As-Sufi in his “Catalog of Fixed Stars”. There is also a depiction of the constellation, where the galaxy appears as a small floating cloud beneath the palm of the right hand of the mythological heroine. The initial observation…
Almost everyone can easily identify the star that is nearest to our planet, although not everyone possesses additional knowledge about it. Fascinating This particular star is classified as a yellow dwarf and emerged approximately 5 billion years ago. The sunlight emitted by the Sun takes merely 8 minutes to reach the Earth, spanning a vast…
Table of Contents Origin The term Milky Way is commonly used in Western culture and is a translation of the Latin term via lactea, meaning “milky way”, which itself is a translation of the Greek term ϰύϰλος γαλαξίας, meaning “milky circle” [16]. The term Galaxy is derived from the ancient Greek word γαλαϰτιϰός, meaning “milky”….
