In our previous discussion, we explored the fascinating journey of lunar meteorites from the Moon to Earth. Today, we will delve into the topic of lunar meteorite discoveries and the challenges inherent in identifying their origin. Challenges in Determining the Source Crater of Lunar Meteorites What is the number of lunar meteorites on Earth? The…

Mercury, the smallest planet in our solar system, is known for its short years, long days, extreme temperatures, and peculiar sunsets. Mercury, the planet closest to the sun, has a faster revolution around the sun compared to other planets. This is why it was named after the Roman god known for his speed, the messenger…

The sun, a magnificent celestial body, emits an immense amount of energy as a result of hydrogen fusion in its core. This fusion process converts hydrogen into helium, and the radiant energy is then released into the vast expanse of space. Throughout history, societies have revered the sun for its crucial role in sustaining life…

The planet we inhabit is surrounded by a vast expanse of air, known as the atmosphere. However, extraterrestrial beings visiting from other regions of our solar system do not share our fascination with Earth’s atmospheric makeup. Interestingly, even the most primitive life forms that first emerged on our planet did not find the prevailing air…

Earth’s atmosphere is a gas shell that surrounds the planet, extending for a certain distance from its surface. The atmosphere covers the hydrosphere and part of the Earth’s crust, and its outer surface meets the near-Earth region of outer space. The scientific disciplines of atmospheric physics, meteorology, and climatology are dedicated to studying the different…

The Solar System consists of the Sun and a variety of celestial objects such as planets, meteorites, asteroids, and comets. These planets have different distances from the Sun, but they all orbit around it in unique paths. The Sun itself is much larger in mass compared to all other celestial bodies in the solar system…

Right ascension (α, R. A. – derived from the English term “right ascension”) represents the length of the arc on the celestial equator from the vernal equinox to the declination circle of the celestial body. Right ascension serves as one of the dimensions in the second equatorial system (the first one being the hour angle)….

The Lunar Dream Calendar for August 18, 2023 provides insight into the meaning of dreams based on the moon phase and the Zodiac sign in which the “night luminary” is located. To interpret dreams on other nights, consult the general lunar dream calendar for August 2023, and for more detailed meanings, refer to the online…

The calculation of 500 light years is based on the assumption that light is not influenced by any gravitational fields. This assumption holds true in a vacuum, where the speed of electromagnetic radiation remains constant. During the 17th century, scientists were engaged in the quest to determine the velocity of light. Prior to this, astronomers…

As an illustration, Pluto did not meet the criteria to be considered a planet according to the second point. It is classified as a dwarf planet. What qualifies as a dwarf planet Similar to regular planets, it orbits and revolves around the Sun. It also has a spherical shape. It does not necessarily have to…

Frequently, you hear the phrase “the sun is at its highest point”. What is the significance of this statement? Where can you currently observe the celestial body in the sky, and how is this location distinct from its other positions and conditions? When during the day or year does this phenomenon take place? And, if…

The emergence of the solar system remains a fascinating enigma in the realm of contemporary science. Numerous hypotheses have been proposed to shed light on this phenomenon, yet no concrete evidence has been discovered thus far. In order to unravel the mysteries surrounding the birth of our solar system, a comprehensive study of its components…

Uranus and Neptune, two of the most mysterious planets in our solar system, have not been extensively studied. While Earth benefits from a vast network of spacecraft that allows us to track satellites almost anywhere, the only human-made object that has come close to these distant planets is Voyager 2. Uranus and Neptune are gas…

Scientists find the diameter of the Earth to be of great practical significance. It can be determined by calculating the circumference of the planet along the equator. The primary characteristics of the Earth Planet Earth is estimated to be at least 4.5 billion years old. It belongs to the terrestrial group of planets, along with…

Actress Yulia Peresild became the fifth Russian to venture into space in the autumn of 2021, while Anna Kikina became the sixth in 2022. Out of the total number of individuals who have traveled to space, 71 of them are women, while more than 500 are men. What is the reason behind this gender disparity?…

A galaxy is a vast system of stars, planets, gas, and dust that are held together by gravitational forces. Galaxies are found throughout the universe and come in a variety of shapes and sizes. They can range from small dwarf galaxies with a few million stars to massive spiral or elliptical galaxies with billions of…

The Moon orbits around the Earth in a path with a major semi-major axis of 383000 km (ellipticity 0.055). The lunar orbit is inclined at an angle of 5°09 to the ecliptic plane. It takes 27 days 7 hours 43 minutes for the Moon to complete one rotation. This is known as the sideric or…

The Hubble Deep Field extreme (XDF) project was finalized in September 2012 and presents a collection of the farthest galaxies ever captured in a photograph. With the exclusion of a small number of stars located in the foreground (which are distinguishable due to their bright appearance and diffraction peaks), each individual entity depicted in the…
