Galaxies:The Universe's Mysteries unveiled

A galaxy is a massive, gravitationally bound system consisting of stars, stellar remnants, interstellar gas, dust, and dark matter. The term originates from the Greek word "galaxias," meaning "milky," a nod to our Milky Way galaxy. Galaxies come in various forms, primarily categorized as spiral, elliptical, and irregular. Spiral galaxies, like the Milky Way and Andromeda, feature rotating disks with spiral arms rich in young stars and active star formation. Elliptical galaxies, ranging from nearly spherical to elongated shapes, contain older stars with minimal new star formation. Irregular galaxies lack a defined shape and often result from gravitational interactions or collisions.

Galaxies are not isolated entities but are part of larger structures such as groups, clusters, and superclusters. For instance, the Local Group includes the Milky Way, Andromeda, and about 54 smaller galaxies. Dark matter, which does not emit light, constitutes a significant part of a galaxy's mass, influencing its rotation and structure. Understanding galaxies is crucial for studying the universe's formation and evolution. Modern telescopes, like the Hubble Space Telescope, offer detailed views of distant galaxies, enhancing our knowledge of their properties and history, and helping to unravel the mysteries of the cosmos.#shorts #viral #new #mystery #galatasaray
