Galaksissamme

Galaksissamme refers to "our galaxy" in Swedish. When discussing astronomy, this term typically denotes the Milky Way galaxy, the spiral galaxy in which Earth and our solar system are located. The Milky Way is a vast collection of stars, gas, dust, and dark matter, bound together by gravity. It is estimated to contain hundreds of billions of stars, including our Sun. Our galaxy is part of the Local Group, a cluster of galaxies that also includes Andromeda, the Triangulum Galaxy, and several smaller dwarf galaxies.

The Milky Way is characterized by its spiral arms, which are regions of active star formation. Our solar system resides in one of these arms, known as the Orion Arm or Orion Spur. From Earth, we perceive the Milky Way as a faint band of light stretching across the night sky, a phenomenon caused by the combined light of distant stars within our galactic plane. Astronomers have been studying the Milky Way for centuries, learning about its structure, composition, and evolution. Modern research utilizes telescopes and other instruments to observe different wavelengths of light and to map the distribution of stars and matter within our galaxy, providing ever-deeper insights into galaksissamme.
