Constellations "When it comes to the Virgo constellation, the stars in the head area, as well as the star at the end of the southern wing, have a striking resemblance to Mercury and, to a lesser extent, to Mars; the other bright stars in the wing and those in the belt have similar appearances to…
The atmosphere of Earth consists of multiple layers of gases that envelop the planet due to the effects of gravitational field. Each layer possesses a distinct gas composition and they are all arranged based on their density. Heavier gases are drawn closer to the surface of the Earth, while lighter gases reside further away from…
II. Practical Fundamentals of Astronomy § 4. Celestial Coordinates and Star Charts Supplementary Materials for the Lesson While there are approximately 6000 stars visible to the naked eye across the entire sky, we can only see half of them due to the Earth obstructing our view. As the Earth spins on its axis, our perspective…
For numerous years, scientists have explained the origin of our universe by merging the hot Big Bang with a singularity. They argue that the Big Bang marked the birth of space and time. However, in the early 1980s, a new concept arose known as cosmic inflation. This theory proposed that before the hot Big Bang,…
The Newtonian reflector telescope, also referred to as the Newton reflector, is the original variant of the reflector telescope, created by Sir Isaac Newton in 1668. This particular design employs a primary concave mirror along with an additional flat diagonal mirror. The Newtonian telescope is well-liked for its straightforward yet efficient design, which is highly…
The Earth’s north pole has a latitude of 90 o, causing the plumb line to align with the world axis and the equator to align with the horizon. Consequently, the Sun traces circles on the celestial sphere that are approximately parallel to the horizon throughout the year, at an altitude equivalent to the Sun’s declination…
Is the number of planets in the solar system actually 9? That’s what we learned in school. However, according to the Sumerian bas-relief, there are 12 planets. It is possible to speculate about the existence of Phaeton in ancient times, as well as a tenth planet that shares the same orbit as Earth but is…
Observatory: Archenhold Observatory Location: Berlin, Germany Lens diameter: 27 inches (70 centimeters) Focal length: 21 meters Year of construction: 1896 This refractor telescope, located at the Archenhold Observatory in Berlin, Germany, boasts a focal length of 21 meters, making it the longest refractor telescope in the world. Interestingly, the weight of its moving parts is…
Uranus, the seventh planet from the Sun, is the third largest and fourth most massive planet in our Solar System. It is 14.5 times more massive than Earth, making it the lightest among the giant planets in our Solar System. Similar to the other gas giants present in our solar system, Uranus possesses its own…
A 24-hour period (plural ancient form collision, junction meaning “the junction of day and night”) is a unit of temporal measurement, approximately equivalent to the duration of the Earth’s rotation around its axis. Typically, a day refers to the astronomical concept of a solar day. In everyday language, a day is often referred to as…
It is important for everyone to have an understanding of their emotions when interacting with others. Saturday is an ideal day to begin new exercise or training regimens. When it comes to interpersonal relationships, it is recommended to only engage with individuals who align with your values and preferences. Show generosity towards others and avoid…
During his observation of the transit of Venus across the Sun, Lomonosov noted that the planet’s outline appeared blurry, indicating the presence of an atmosphere. This groundbreaking discovery by the scientist had immense significance for the field of astronomy worldwide. It provided evidence that planets within the solar system possess a complex structure and can…
While numerous lunar events occur within a single night, one particular lunar phenomenon is much less elusive: the moon’s glowing rings. These luminous white rings, also referred to as lunar halos or simply halos, can manifest at any point on the lunar calendar and during any season, particularly in winter. However, if you desire to…
In the past, our ancestors only associated the solar system with the concept of the universe. Nowadays, we are aware that the solar system is minuscule in comparison to the galaxy and that the universe is truly vast, stretching beyond our wildest imagination. Scientists are actively gathering information about the planets, delving into their origins…
Researchers at the Israel Institute of Technology have successfully generated a sonic equivalent of a black hole in a controlled laboratory setting, providing concrete evidence of the existence of stable Hawking radiation. Previously, a team of physicists from Mexico and Israel had demonstrated the presence of Hawking radiation using ultra-short laser pulses and photonic crystal…
On a clear night, an individual can observe approximately two to three thousand stars in the nighttime sky with their unaided eyes. However, these stars appear so similar that distinguishing between them can be challenging. This video lesson provides insights into the names of constellations and the origins of their names. It also delves into…
Universe What is a pulsar? A pulsar is a celestial object that emits periodic bursts of radio, optical, X-ray, and/or gamma-ray radiation. It is a small rotating star in which a specific area on its surface emits a narrow beam of radio waves into outer space. When this beam is directed towards Earth, our radio…
Its codename was PS-1, also known as the simplest satellite-1. By today’s standards, it may seem primitive. However, this small metal sphere with a radio transmitter marked the beginning of the space age and demonstrated the technological prowess of the country that brought it to life. Natalia Tikhonravova, the daughter of one of the satellite’s…
The following equations provide an estimate of the potential capabilities of a telescope. It’s important to note that these equations are theoretical and actual performance may vary based on the quality of the telescope, proper calibration, and atmospheric conditions. The telescope’s magnification (G) G=F/f where F represents the focal length of the objective lens and…
Residents of the Southern Hemisphere will have the exclusive opportunity to witness a total solar eclipse on December 4, 2021. In this article, we will provide you with detailed information about this remarkable celestial event. It is important to note that when observing the Sun during the eclipse, it is crucial to use a protective…
