In the Name of Allah---the Most Beneficent, the Most Merciful. A galaxy is a vast system of stars, stellar remnants, interstellar gas, dust, dark matter, and other celestial objects, all bound together by gravity. A galaxy is a vast system of stars, stellar remnants, interstellar gas, dust, dark matter, and other celestial objects, all bound together by gravity. The observable universe contains hundreds of billions of galaxies, each varying in size, structure, and composition. Galaxies are classified into several main types based on their shape and appearance. Types of Galaxies Spiral Galaxies Structure : Spiral galaxies consist of a flat, rotating disk containing stars, gas, and dust, along with a central bulge made up mostly of older stars. The disk often features spiral arms that emanate from the central bulge. Subtypes : Normal Spirals (Sa, Sb, Sc) : Classified based on the tightness of their spiral arms and the size of their central bulge. Sa galaxies have tightly wound arms and l...

In the Name of Allah---the Most Beneficent, the Most Merciful. Astronomers have made a groundbreaking discovery using the James Webb Space Telescope (JWST), identifying an extraordinarily large, radiant and the oldest galaxy, Introduction Astronomers have made a  groundbreaking discovery  using the James Webb Space Telescope (JWST), identifying an extraordinarily large, radiant, and the oldest galaxy, JADES-GS-z14-0, that existed a mere 290 million years after the Big Bang. This detection marks the youngest system ever observed and provides profound insights into the early universe’s formation and evolution. The James Webb Space Telescope: A Technological Marvel The JWST, launched in December 2021, represents the pinnacle of astronomical observation technology. Equipped with state-of-the-art instruments, the telescope allows scientists to peer deeper into space and time than ever before. By capturing infrared light, JWST can observe distant objects whose light has been stretch...
