Orion Constellation’s shoulder, composed of the red supergiant Betelgeuse, one of the brightest stars in the sky, underwent one of the most prominent brightness variations ever recorded in modern astronomy history at the end of 2019. During this event, known as the “Great Dimming,” the star’s brightness dropped below its normal level, becoming noticeably darker to the naked eye. This process, which began in late 2019 and lasted into early 2020, sparked global speculation that the star might be a

The Sun is the source of everything on Earth. Our light, our heat, our seasons—all are made possible by the Sun’s steady luminosity. But a major question arises in the mind: What happens when the Sun one day dies?First, it is essential to understand:The Sun is not a star capable of exploding like a supernova. The reason is its relatively small mass. Supernova explosions occur only in massive stars with at least eight to ten times the mass of the Sun. Therefore, the Sun’s fate is not to explode,

The Cat’s Eye Nebula (NGC 6543) is a planetary nebula located approximately 3,300 light-years from Earth in the constellation Draco. It is renowned for its highly complex structure.First discovered in 1786 by William Herschel, this nebula has attracted significant scientific interest due to high-resolution images captured by the Hubble Space Telescope. It holds major astrophysical importance, particularly for its reflection of the late evolutionary phase of its central star.General PropertiesAlt

NGC 6822, commonly known as Barnard’s Galaxy, is one of the irregular dwarf galaxies belonging to the Local Group. Discovered in 1884 by American astronomer Edward Emerson Barnard, this celestial object is a low-mass and low-luminosity system, unlike the larger members of the Local Group such as Andromeda and Triangulum. Due to its relative proximity to the Milky Way and its structural characteristics, NGC 6822 holds potential for shedding light on the early stages of galaxy formation and evolut

A black dwarf is a hypothetical celestial object that emerges in the final stage of a star’s life. In reality, black dwarfs are the end result of white dwarfs that have completely cooled and no longer emit any light. They are therefore extremely aged stars that have lost all their energy.But do not worry—no black dwarfs have yet formed in the universe! This is because it takes trillions of years for a star to evolve into a black dwarf.How Do Black Dwarfs Form?Stars are born, live, and die. Stars

Brief Answers to the Big Questions (original title: Brief Answers to the Big Questions) is a popular science book written by British theoretical physicist Stephen Hawking. The book aims to provide short and direct answers to fundamental questions about the universe, life, humanity, and scientific inquiry.Content and ThemesThe book presents information within the context of fundamental cosmology the nature of the universe and the future of humanity. Major themes include:The Universe and Cosmology

The Heliocentric Model is a cosmological system that posits the Sun as the center of the universe and the planets orbiting around it. This model was systematically presented in 1543 by Nicolaus Copernicus with its mathematical and theoretical foundations, thereby providing a fundamental alternative to the long-dominant Geocentric Model. Copernicus’s system is historically decisive not only for astronomy but also for initiating a “paradigm shift” within the broader framework of Western thought.Hi

Before the universe was even a thought, there was no time, no space. No light had fallen upon darkness, nor had darkness cast a shadow upon emptiness. In that indescribable silence between existence and nonexistence, only Brahman existed—formless, timeless, and boundless… The absolute essence, source of all things, yet none of them.In profound stillness, a vibration arose from within Brahman—an aimless quest, an endless stir. This vibration echoed as a sound: Om. Neither word nor melody, it was

Hoba Meteorite is a natural celestial body composed primarily of iron and nickel, located near the town of Grootfontein in northern Namibia, southwestern Africa. With a weight of approximately 60 tons, it is the largest single-piece meteorite known on Earth.Hoba Meteorite: The Largest Known Single-Piece Meteorite on EarthMeteorites are regarded as cosmic messengers carrying traces of the universe’s past. These stones are not only objects of scientific curiosity but also possess the status of nat

The universe is a vast whole that expands in dimensions of time and space, had a beginning, but whose boundaries are not precisely known, and contains billions of galaxies.The Boundary Open to the Sky: How Much of the Universe Can We See?Since its existence, humanity has looked to the sky and questioned its place in the universe. As our observations have advanced, we have come to realize that we can directly observe only a small portion of the universe. This visible part is scientifically define
