What else can I help you with?
Name four different objects you can find in our 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.
General structure of a Milky Way galaxy?
The Milky Way galaxy is a spiral galaxy with a central bulge, a disk made up of arms of gas, dust, and stars, and a halo of globular clusters. The central bulge contains older stars, while the disk is where younger stars are formed. The galaxy is surrounded by a halo of dark matter that extends beyond the visible components.
What Is thin gas and clusters of stars surrounds the disk of the milky way galaxy?
what is the thin gas and clusters of stars surrounds the disk of the Milky Way Galaxy.
Whats the shape of the Milky Way?
It looks more like a gigantic disk, with a bulge in the middle.
Which stars were born first as the Milky Way formed?
The stars throughout the disk.
Milky way made of?
The Milky Way is a barred spiral galaxy that contains billions of stars, dust, and gas. It is held together by gravity and has a central bulge surrounded by a disk. Our solar system resides in one of the spiral arms of the Milky Way.
Why is the milky way shape similar to a fried egg?
The Milky Way's shape resembles a fried egg due to its flattened disk structure with a central bulge, similar to the yolk of the egg. The disk contains stars, gas, and dust, while the bulge houses older stars concentrated at the center. Just like the egg white spreads out around the yolk, the galaxy's spiral arms extend outward from the central region, creating a visually similar appearance. This analogy highlights the galaxy's overall structure and distribution of materials.
Who discovered that the milky way was a disk of stars?
The realization that the Milky Way is a disk of stars was largely attributed to the work of astronomers in the 18th century, particularly Immanuel Kant. He proposed that the Milky Way was a vast collection of stars, which later observations by astronomers like William Herschel in the late 1700s provided further evidence for. Herschel's star counts and mapping of the Milky Way's structure helped reinforce the understanding of its disk-like shape.
How do spirals form?
Spiral galaxies form from the collapse of a protogalactic cloud. Spiral galaxies consist of three components: a rotating disk, a bulge and a halo. Spiral galaxies, like the Milky Way, owe their shape to stars inside the protogalaxy developing at different intervals. The gas between forming stars continues to be compressed, and the resulting gravitational differences manhandle the protogalaxy's stars, dust and gas. When the protogalactic cloud collapses, the stars in the bulge and halo form first. These stars have rather random orbits around the galactic center. The galactic center probably contains a supermassive black hole, which likely exerts some gravitational influence on the formation of a spiral galaxy. The remainder of the cloud forms a disk due to the conservation of angular momentum (the same effect as the spinning up of the dancer when she pulls her arms inside). This motion forces everything into a rotating disk, and additional differences in gravity build the spiral arms. Oppositely, when a protogalaxy's stars develop at the same time, you have an elliptical galaxy on your hands. The stars in the disk form later and thus the disk population of stars are younger than those in the bulge and the halo. Further, the stars in the disk rotate around the center of the galaxy in a collective, well defined way unlike the stars in the bulge and halo.
What are three parts of the Galaxy?
The Galaxy, specifically the Milky Way, consists of three main parts: the stellar disk, the bulge, and the halo. The stellar disk contains most of the Galaxy's young stars, gas, and dust, where star formation occurs. The bulge is a densely packed region of older stars located at the center, often housing a supermassive black hole. The halo surrounds the Galaxy, containing older stars, globular clusters, and dark matter, providing a gravitational framework for the Galaxy's structure.
What make up the Milky Way?
The Milky Way is a spiral galaxy composed of stars, gas, dust, and dark matter. It contains billions of stars, including our sun, and is structured with a central bulge, a disk where the spiral arms are located, and a halo.
Why does the milky way look like a hazy band of stars in the sky?
The Milky Way appears as a hazy band of stars in the sky because we are viewing it edge-on from within the galaxy. The combined light of billions of distant stars, interstellar gas, and dust within the plane of the galaxy creates this band of light across the night sky.
