When gazing at the dark expanse of the night sky, numerous individuals have witnessed the descent of celestial bodies resembling stars. However, the distinguishable trail left behind is not a result of these “falling stars,” but rather from a different type of extraterrestrial object known as meteorites. On a daily basis, a substantial quantity of…

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…

Indeed, the progression of galaxies is the process of their advancement. It is accompanied by alterations in structure and composition. Let’s explore how galactic modifications transpired.We can identify three primary stages in the galaxy’s history: Advancement is an actuality, not a hypothesisCarl Sagan The formation of galaxies: a journey from the Big Bang Now, let…

The measurement of the distance to galaxies is a fascinating topic in astronomy. One common method used by scientists is the concept of light-years, which is a unit of measurement based on the distance that light travels in one year. The Milky Way Galaxy, for example, is approximately 1,000 light-years thick and has a diameter…

The Big Dipper is a well-known constellation in the night sky. With its bright stars, it is easily recognizable even without the use of a telescope. In ancient times, it was used as a guide for travelers, and today astronomers continue to study this cluster of stars. The Big Dipper is a frequent subject of…

The device and operation of different optical devices are based on the principles of geometrical optics. Let’s examine a few of them. An opaque camera and a lens system called a lens are the main components of a camera. The most basic lens is a single collecting lens. This lens forms a real inverted image…

As we gaze up at the sparkling night sky, the vastness of the space between the stars becomes apparent. Although they may appear as tiny specks, in reality, the stars are not small at all. In fact, the distance between us and them is akin to a colossal abyss. Moreover, the gap between the stars…

It is common knowledge that throughout history, individuals have relied on star coordinates to navigate their lives. Navigators, for instance, used celestial bodies to orient themselves in space, and this knowledge extended beyond them. Agricultural activities were timed in accordance with the position of the stars, and much more. In fact, calendars were developed that…

Discussions on the subject of summer, winter, belt, local, and astronomical time have inspired me to write this post. I will share with you how to calculate local time and explain what zone time is.

Thanks to the James Webb telescope, we now have concrete evidence to support this claim. We are now observing galaxies that are significantly older than what the standard cosmological model can account for. These galaxies appear to be more advanced and evolved than expected. However, some scientists propose that our understanding of the universe’s current…

The troposphere extends up to different altitudes depending on the latitude. In polar latitudes, its upper boundary is at an altitude of 8-10 km. In temperate latitudes, it reaches up to 10-12 km, and in tropical latitudes, it extends as high as 16-18 km. These altitudes may vary, being lower in winter and higher in…

This video tutorial will explore the composition of the Sun’s atmosphere. We will discover the specific layer of the Sun that emits its visible radiation. We will become acquainted with the unique entities and occurrences within the Sun’s atmosphere. Additionally, we will uncover the concept of solar activity and its cyclic nature.

There is perhaps no constellation in the northern hemisphere sky that is more well-known than the Little Bear. It is the one that children often inquire about and even attempt to spot in the night sky. Why has it garnered such special attention, considering that the Little Dipper appears rather unassuming? Primarily because it is…

In previous lessons, we have learned that just like other stars, the Sun appears to move across the celestial sphere. Similarly, the Moon also moves in relation to the stars, but its trajectory is more complex. In this lesson, we will explore the reason why the Moon always presents the same face to Earth. We…

Unlike its terrestrial counterparts, such as Earth, Saturn lacks a solid outer layer. The visible region we perceive as its “surface” actually consists of its cloud cover. Table of Contents Which celestial body is not visible to the naked eye? Which planet is the most visible from Earth? What is the astronomical object that appears…

According to the author, when viewed through a telescope, the Moon appears brighter, more contrasting, and with more relief. In Rostov-on-Don, anyone passing by had the opportunity to gaze at the Moon. A regular moon captured by an SLR camera. I always believed that through a telescope, one could spot lunatics). A regular camera, without…

Throughout history, individuals fascinated by outer space have been captivated by the moon. This celestial body, with its gray hue, has been estimated to be approximately 4.6 billion years old, equivalent to the age of our planet.
