網頁2024年7月25日 · The Milky Way Galaxy. When we stare up into the heavens on a clear night, away from light pollution and other distractions, we can see a milky bar of light that spans across the sky. This is how our home galaxy, the Milky Way, got its name, and it's how it looks from the inside. The Milky Way is estimated to span between 100,000 and … The Milky Way consists of a bar-shaped core region surrounded by a warped disk of gas, dust and stars. The mass distribution within the Milky Way closely resembles the type Sbc in the Hubble classification, which represents spiral galaxies with relatively loosely wound arms. Astronomers first began to conjecture that the Milky Way is a barred spiral galaxy, rather than an ordinary spiral galaxy, in the 1960s. These conjectures were confirmed by the Spitzer Space Telescope observa… thunderbird lodge canyon de chelly reviews
