What is the actual color of the Sun? Due to the unique characteristics of the human eye, the Sun appears to be a vibrant shade of yellow or orange. However, in actuality, the light emitted by the Sun is white. This optical illusion occurs because the direct sunlight that reaches the Earth’s surface undergoes molecular…

Planet earth stands out among the other celestial bodies in our solar system. It is not the smallest nor the largest; it holds the fifth position in terms of size. When compared to other planets in the Earth group, it surpasses them in mass, diameter, and density. Since the Earth is located in outer space,…

In which galaxy is planet Earth located? What is the name of our galaxy? We reside on one of the entities within the Solar System – the Milky Way conglomerate. In various cultural interpretations, the designation of our galaxy may vary, but the concept of a “path” is consistently emphasized. The term “Milky” can be…

A galaxy is a vast assemblage of stars, stardust, gases, cosmic rays, and enigmatic dark matter. Galaxies are scattered throughout the vast expanse of the universe. Our very own galaxy is known as the Milky Way. We affectionately refer to it as our galaxy because that’s where our home planet Earth resides. Furthermore, galaxies themselves…

We are all familiar with the concept that space is something that exists outside of our planet, encompassing the entire universe. Essentially, space is an infinite expanse that extends in all directions, containing galaxies and stars, black holes and planets, as well as space debris and various other objects. The prevailing belief is that there…

Aldebaran is a celestial body that is often referred to as the “eye of the bull” in the constellation Taurus. It is one of the brightest stars in the night sky and is easily visible to the naked eye. Aldebaran is classified as a red giant, meaning it has reached the later stages of its…

Hans Lipperschlei of Holland is often credited with inventing the first telescope, but it is likely that he was not the true discoverer. Instead, he is recognized for popularizing and making the telescope instrument widely sought after. In 1608, he applied for a patent for a pair of lenses housed in a tube, which he…

The moon is the only celestial object in our sky that visibly changes its shape. While the sun always remains the same – round and incredibly bright (except during rare eclipses) – stars and planets typically maintain their shape, unless observed with a telescope. The appearance of the moon, however, undergoes distinct transformations, resembling a…

The Aurora is a natural occurrence of luminous light in the nighttime sky, predominantly in the polar regions of the Earth and other celestial bodies. This dazzling light display can appear in an array of vibrant hues – such as violet, indigo, emerald, golden, and crimson – and can manifest in various shapes, including stripes,…

Stars are enormous celestial bodies composed of plasma that are held together by the force of gravity. As you might be aware, the Sun is the closest star to Earth and is located at the center of our solar system. With a diameter of approximately 1,392,684 kilometers, the Sun is relatively small when compared to…

Truly, the celestial sky presents a rather disorderly scene. It takes a highly developed imagination to perceive, much like the ancients did, the random arrangement of stars as human figures, animals, and various objects. However, there are some genuinely remarkable star formations that capture one’s attention! One such example is the renowned Big Dipper, which…

The constellation Kiel or Carinae can be found in the Southern sky in the second quadrant, covering an area of 494.2 square degrees. It is comprised of various groups of stars that are easily distinguishable due to their cross-like formations, as well as captivating nebulae and galaxies that radiate cosmic beauty. Among the largest of…

Throughout the ages, individuals have observed the Sun’s movements during daylight hours and the behaviors exhibited by the Moon and stars at night. They have been curious about the causes behind these phenomena. In more recent times, scientists and astronomers have been able to conduct research on these celestial bodies in order to elucidate their…

The definition of “constellation” has evolved over time. In present day, a constellation is generally defined as a specific area within the celestial sphere. Astronomy, an ancient science, has its roots in the distant past. In earlier times, people, particularly travelers, had a keen interest in astronomy as they relied on the stars for navigation….

Astronomy became the first field of study to achieve a high level of understanding, capable of making accurate predictions about the movements of celestial bodies as early as the second half of the 1st millennium BC. The early success of astronomy, in comparison to other natural sciences like physics, chemistry, and biology, can be attributed…

The constellation known as the Swan can be found in the starry sky of the northern hemisphere. Its bright stars form a distinctive cross-shaped pattern, known as the Northern Cross, which stretches along the Milky Way. This pattern has long been associated with flying birds, with the Babylonians referring to the constellation as the “forest…

The majority of our universe is composed of an elusive substance known as dark matter, which remains invisible and undetectable to our instruments due to its lack of interaction with ordinary matter. However, against all odds, a team of researchers at the Atacama Telescope has achieved the remarkable feat of mapping this enigmatic dark matter,…

The emergence of practical cosmonautics occurred during a period of intense ideological and military-political confrontation between the USSR and the USA. The “Cold War,” which was officially declared by Winston Churchill in his renowned Fulton speech on March 5, 1946, fueled competition between the two nations across all aspects of life. It soon became clear…

Regrettably, the majority of individuals have lost touch with the awe-inspiring beauty of the Milky Way! Our lives are now centered in urban environments where the night sky is relentlessly brightened by the glow of streetlights, luminous advertisements, and passing vehicle headlights. Moreover, in metropolitan areas, the air is often filled with smog, which efficiently…
