The Galactic Center
At the heart of the Milky Way lies a supermassive dark gap known as Sagittarius A*. This dark gap has a mass million of times that of our Sun and influences the movement of stars and gas around it. The galactic center is moreover a region of strongly movement, including the outflow of high-energy gamma beams.
Galactic Disk and Spiral Arms
The Milky Way has a flat, rotating disk that contains most of its stars, gas, and dust. This disk features winding arms that wind out from the center, making wonderful, swirling designs. These arms are regions where new stars are born, as the dense gas and dust provide the necessary fixings for star arrangement. The formation and dispersal of these arms occur over relatively brief periods, approximately 100 million years.
The Halo and Dark Matter
Surrounding the Milky Way is a halo made up of old stars and globular clusters, as well an endless amount of dark matter. This matter doesn’t radiate light, so we can’t see it directly. However, know it’s there since its gravitational impacts on movement of gas in universe. Dark makes almost 90% of Way’s mass.
Satellite Galaxies
The Milky Way is not alone in space. It has numerous smaller companion galaxies circling around it. Two of the most well-known satellite galaxies are the Huge and Little Magellanic Clouds. These worlds are rich in gas and are an association with the Milky Way, influencing its shape and movement. Researchers believe there may be hundreds more little satellite galaxies holding up to be found.
Stellar Populations and Star Clusters
The Milky Way contains a wide assortment of stars, from youthful, shinning stars in the spiral arms to old, dim stars in the galactic bulge. The bulge, a thick region at the center of the universe, contains a few of the oldest stars in the Milky Way. Scattered all through the world are globular clusters, which are groups of ancient stars that give clues about the early history of the Smooth Way.
Mystery Substructures in the External Disk
Recent studies have revealed mysterious thread-like structures in the external regions of the Milky Way’s disk. These substructures, such as the Anticenter Stream, contain stars that are billions of years old. Researchers are attempting to determine whether these highlights are genuine parts of the disk or optical illusions made by thickness waves.
Cosmic Rays and High-Energy Phenomena
The Milky Way is a source of cosmic beams, high-energy particles that travel through space. Researchers are considering these rays to get it their beginnings and how they influence our galaxy. These particles are associated to different high-energy forms, such as supernovae, which are blasts of massive stars.
