Elliptical galaxies.
Stars form in the great clouds of gas and dust in the spiral arms of a galaxy.
Interstellar dust
Our galaxy, the Milky Way, is a spiral galaxy. It consists of a central bulge surrounded by spiral arms that contain stars, gas, and dust. We are located on one of the outer arms of the galaxy.
A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a "bulge," a "disk" containing "spiral arms," and a "halo." Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.
The galaxy you are describing is a spiral galaxy. These galaxies typically have a dense, thick center known as the bulge, composed of stars and gas, along with flattened arms that extend outward, where stars, dust, and gas are concentrated. The Milky Way is a prime example of a spiral galaxy with these characteristics.
You are looking through one of the spiral arms of our galaxy (the "Orion Arm", I think, but not 100% sure on that) toward the center of the galaxy. We cannot see the center of the galaxy with the naked eye because there is 30,000 light years worth of gas and dust in the way, but infrared photography (in which the gas and dust are transparent) shows it clearly.
a spiral galaxy
A flattened combination of matter containing stars, gas, and dust in a spiral galaxy is identified as the galaxy's disk. This disk is where most of the galaxy's star formation occurs and contains the majority of its stars and interstellar material. The spiral arms within the disk are regions of higher density that enhance star formation.
This represents a galaxy, which is a massive collection of stars, gas, dust, and other celestial objects bound together by gravity. The Milky Way is an example of a galaxy that contains millions of stars, along with interstellar gas and dust.
A flattened combination of matter containing stars, gas, and dust in a spiral galaxy is known as the galaxy's "disk." This disk structure is characterized by its spiral arms, where star formation occurs, and it contains most of the galaxy's visible matter. The disk is surrounded by a more spherical halo of stars, globular clusters, and dark matter.
