Planet Earth is a treasure trove of enigmas, with one of the most intriguing being the mystery of its innermost core. While human-made mines can only delve a few kilometers deep, the secrets residing deep within our planet remain inaccessible. Nevertheless, scientists have managed to piece together a rough sketch of its internal composition.
Galaxies are enormous groups of stars, interstellar gas, and cosmic dust. Each one contains millions to trillions of stars. When you observe the most distant galaxies with a regular telescope, they appear as hazy luminous spots. There are three primary categories of galaxies in the Universe – elliptical-shaped galaxies, spiral galaxies, and irregularly shaped galaxies….
Upon viewing this instructional video, you will acquire knowledge regarding the Earth’s form and dimensions. You will familiarize yourself with the methodology of triangulation for gauging the length of the meridian arc. Additionally, we will explore the concept of horizontal parallax and angular radius of a celestial object, and discover their utility in ascertaining the…
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…
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 Andromeda constellation can be found in the northern hemisphere, situated between Pegasus and Cassiopeia. It was named after the mythical Princess Andromeda. Although it was mentioned in catalogs as early as the 2nd century by Ptolemy, it was officially recognized in the 17th century. The Origin and Mythology of the Andromeda Constellation The Andromeda…
Mass (in solar masses): 0.045 Type: Brown dwarf Distance: 11.83 sv years Constellation: Indian Age: 1.3 billion years old Year of discovery: 2003 Epsilon Indian is among the nearest stars to our solar system. It is visible from Earth as a moderately bright star. The brightest star in Epsilon Indian’s sky is Canopus, followed by…
For the brilliant minds in the field of astronomy who value accuracy, the question arises: Which planet is the closest to the Sun? While this may not come as a shock, those who are less interested in the subject might easily forget the answer. Nevertheless, I am here to enlighten you on the matter of…
Gas planets are celestial bodies with a composition predominantly made up of gases. They are part of the solar system, which consists of eight planets. While stars are sources of energy due to thermonuclear reactions in their interiors, gas planets do not have such reactions and rely on other sources for their energy. There are…
Few stars receive names without any reference to their position within a constellation or in the sky as a whole. One of the most significant examples of this is the brightest star in Earth’s sky, Sirius. The name Sirius is believed to have originated from the Greek word Serios, meaning “burning” or “sultry”. This is…
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…
Out of the many moons that orbit Jupiter, eight are considered to be permanent satellites. These satellites have ProGrade orbits, meaning they move in the same direction as Jupiter’s rotation, and their orbits are nearly circular and not highly inclined with respect to Jupiter’s equatorial plane. The most famous of these satellites are the Galilean…
The stratosphere, derived from the Latin word “stratum” which means planking or layer, is a specific layer of the atmosphere that exists at an altitude ranging from 11 to 50 kilometers. It is characterized by a minimal change in temperature within the range of 11-25 kilometers (known as the lower stratosphere layer), and a gradual…
The solar system is home to numerous celestial bodies that are notable for their size. The solar system’s biggest star Undoubtedly, the Sun holds the title of the biggest star within our solar system. Its massive size of 1.4 million kilometers makes it stand out from the rest. While there is a possibility of the…
Where can we find the boundary where the new universe commences and the well-known solar system comes to a close? Typically, we confine our focus to Earth and its neighboring planets. However, let us venture out into our celestial abode, journeying as far away from our sun as possible, and explore the outermost reaches of…
Jupiter is not just the biggest planet in our solar system, it is also one of the most enigmatic. With a size 317 times that of Earth and 2.7 times greater than all the other planets combined, Jupiter boasts a ring system and numerous moons. Engagement Bands The rings of Jupiter were initially discovered by…
A meteor is a small celestial body that enters the Earth’s atmosphere and burns up, creating a bright streak of light in the sky. It is commonly referred to as a shooting star or falling star. Meteors are typically composed of rock or metal and can range in size from tiny grains to larger objects….
Scientists have been investigating the enormity of the solar system for centuries, observing the various categories of planets. With the discovery of exoplanets, our knowledge has expanded even further. In addition to gas giants, we have come across planets that resemble Earth. What exactly are these Earth-like planets? Defining Earth-like Planets An Earth-like planet is…
Education Originally formed 4.5 billion years ago, the solar system consists of eight planets with different sizes and distances from the Sun. Some scientists have speculated that there may have been a ninth planet in the past, which is either beyond the reach of current observation methods or was destroyed due to natural or other…
