According to The Guardian, astronomers searching for extraterrestrial radio signals have picked up an “interesting signal” from Proxima Centauri, the nearest star system to our Sun. Here, we provide further details on the findings made by scientists. Discover “Hitech” in Who is Proxima Centauri? Proxima Centauri, a red dwarf star, is part of the Alpha…

The Earth’s north pole is aligned with a point in the sky that is remarkably close to the position of Polaris. Consequently, as the Earth spins on its axis, it gives the illusion that Polaris is stationary while all the other stars orbit around it. Taken with a Sony ILCE-7C camera and a Tamron 11-20mm…

A regular polygon is a convex polygon where all sides and angles between adjacent sides are equal. In simple terms, to create a polygon, we need a circle. By dividing 360 degrees by the desired number of vertices, we can determine the angle at which the rays will be displaced, and this angle will be…

For a considerable period, humanity’s endeavors to investigate the Moon were constrained to visual observation using optical equipment. In 1959, a new phase in the exploration of Earth’s natural satellite commenced with the successful landing of the Soviet automated station Luna-2. A decade later, American astronaut Neil Armstrong took his first steps on the Moon….

The Earth’s lithosphere is a rigid outer layer that encases the planet. It acts as a shield, safeguarding the surface from extreme temperatures emanating from the planet’s core. Exploring the composition and characteristics of the lithosphere can provide insights into its distinctions from other celestial bodies. Key features The lithosphere is situated between the hydrosphere…

Following the successful launch of the Artemis I mission in late 2022, NASA has been preparing for the upcoming Artemis II, III, and IV missions. While the first mission was unmanned, the second mission aimed to orbit the moon with a crew, and the third and fourth missions are planned to land humans on the…

Pollux, also known as beta Gemini, is an exceptional star. It is renowned for being the most brilliant star in the Gemini constellation. However, some argue that labeling it as a beta star is a logical fallacy. Overview Pollux, also known as Beta Gemini, is the most luminous star in the Gemini constellation and the…

When it comes to the center of a black hole, conventional wisdom tells us about the singularity – an incredibly tiny and densely packed point where matter is compressed to its maximum and our understanding of space-time breaks down completely. However, what if this widely accepted notion is not entirely accurate? Are there any other…

TASS-DOSIER. A decade ago, on February 15, 2013, a massive meteorite detonated in the sky above the Chelyabinsk region, reaching heights of 15-25 km. This event marked the largest impact of a celestial body on Earth since the Tunguska meteorite in 1908. TASS has compiled a report detailing this extraordinary occurrence. The occurrence of the…

During the spring season, it is traditional to observe Mercury, the planet closest to the Sun and therefore the most difficult to spot in the sky. This year, Mercury will be visible in the first half of the month. It is possible to locate the planet without the need for any optical instruments, as long…

The atmosphere of Uranus, while sharing a similar chemical makeup with other gas giants, possesses unique characteristics. These characteristics pertain to the structure of the atmosphere and the various processes taking place within each of its regions. The abundance of ice and the presence of multiple cloud layers, each with its own distinct chemical 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…

Planets in our solar system come in different sizes and shapes. They range from being extremely large to being relatively small compared to their moons. For instance, Mercury is smaller than Ganymede. Additionally, some planets have a larger diameter at the equator compared to their poles. Let’s explore the diameters of the planets in the…

Constellations Cepheus (also known as Cepheus) is a constellation located in the Northern Hemisphere of the sky. It has an irregular pentagon shape. The southern part of the constellation can be found along the Milky Way. Cepheus covers an area of 587.8 square degrees in the sky and contains 148 stars that can be seen…

Stellar magnitude, also known as visible stellar magnitude, is a dimensionless numerical value used to describe the brightness of celestial objects, primarily stars, as seen from the observer’s location. It takes into account both the amount of light emitted by the object and its distance from the observer. Stellar magnitude serves as a metric for…
