Each celestial body possesses a core within its structure. Typically, this core is comprised of multiple layers, serving as a foundational element for the spherical body. The substances present within the core exhibit extraordinary properties. For instance, iron, found at significant depths in the central region of the planet, has the ability to crystallize or…

Ancient civilizations believed that Mercury, the first planet of the solar system, possessed incredible speed. This led them to name the planet after the swift messenger of the gods. However, modern researchers have discovered that Mercury’s swift movement is a result of its close proximity to the Sun. Through detailed studies, scientists have unraveled the…

The spiral galaxy (abbreviated as S) is one of the primary forms of galaxies, a category of galaxies in the Hubble sequence that possesses the following physical characteristics: * notable overall rotational momentum; * composed of a central bulge (a nearly spherical thickening) encompassed by a disk: * the bulge bears a similarity to an…

The distance from Earth to space, as measured in kilometers (km), is approximately equal to the distance from the planet’s surface to the outer edge of its atmosphere, where the vast expanse of the cosmic vacuum begins. In the 1970s, the Gemini 11 spacecraft reached a record altitude of 1,372 kilometers in its attempts to…

Bolides are celestial objects that enter our planet’s atmosphere periodically. They are characterized by their size and brightness. Essentially, bolides are meteoroids or meteors that have a brightness greater than that of Venus, specifically above -4m. About velocity and luminosity Meteoroids that penetrate the Earth’s atmosphere can range in size from minuscule to several hundred…

The term “Big Bang” refers to two interconnected concepts – the specific event that led to the formation of the universe, and the theory explaining its early development. Approximately 13.8 billion years ago, the universe existed in an incredibly compact, intensely hot, and dense state known as the cosmological singularity. It was during this period…

This webpage provides details about the present and projected position of Mars in the solar system and in the sky based on your location, along with its apparent brightness, size, luminosity, and more. Discover where Mars is currently located in the sky The chart displays the altitude of Mars above the horizon (—°) at different…

In a previous blog post entitled “Coordinates of Wonders,” I discussed known or suspected supernovae that have occurred within historical time. The most recent recorded events on Earth were during the early days of optical astronomy: in 1572 (known as Brahe’s star) and in 1604 (known as Kepler’s star). The fact that only 32 years…

Always visible in the night sky, Queen Cassiopeia is one of the 88 constellations. Its unique shape resembles the letter “W”. Where to find and observe Cassiopeia A diagram illustrating the appearance of the star constellation Cassiopeia. It is possible to observe the star constellation Cassiopeia throughout the year in the mid latitudes of the…

Stars never fail to captivate with their enigmatic charm, leaving us no choice but to let our imaginations run wild as we gaze up at the night sky. It’s almost as if stars are celestial beings, their brilliance magnified by the multitude of souls they house. Yet, despite our comprehension of the scientific facts surrounding…

What are the processes that occur within stars, and how can we qualitatively determine the abundance of chemical elements in our surroundings? It is interesting to consider which elements are more abundant and which are less so. We don’t have to look very far for examples: the sands found on beaches and in deserts contain…

The Red Army Air Defense Artillery, also known as 2MW, had not spread by the beginning of the Great Patriotic War. In the pre-war years, there were tankettes and small tanks of pre-war construction in the Soviet tanks of the beginning of the war (01). The Russian Navy had cruisers of the Baltic Fleet, which…

The age of rocks can be determined using radiometric methods, which are based on physics. By studying rocks from Earth, the moon, and meteorites, scientists have been able to measure their age by examining the decay of long-lasting isotopes of radioactive elements. These isotopes are present in minerals and rocks, and their half-lives can range…

In the vast expanse of the starry sky, numerous constellations can be observed. However, the question arises: what exactly is a constellation? Despite our familiarity with this term, its true meaning may not be clear to those who do not have an interest in astronomy. If one were to inquire about the definition of a…

Even five decades after the historic moon landing, there are still numerous individuals who believe that the journey to Earth’s satellite was a colossal and costly hoax orchestrated by the American government in an attempt to deceive the entire planet. According to experts at NASA, the initial doubts arose when Neil Armstrong, Buzz Aldrin, and…

Astrology, the ancient field of study, asserts that the stars have a profound impact on human existence. This belief is widely accepted in modern times, as astrological predictions continue to captivate audiences around the world. For ages, individuals have been fascinated by the enigmatic celestial bodies that emerge in the nightly sky. As far back…

A black hole is a celestial object characterized by an extremely powerful gravitational pull that not even light particles can escape from. These massive gravitational forces result from the compression of matter into a highly compacted space. Scientists believe that similar processes take place during the death of stars, leading to the creation of black…

The subject of space has always captivated human curiosity. The possibility of space travel and the exploration of distant, uncharted worlds has always intrigued us. As we know, the Moon is the closest celestial body to our planet. Thus, during the early days of space exploration, the dream was to reach the Moon. Surely, in…
