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.
Why does the milky way look like a hazy band of stars in the sky?
The galaxy is covered in dust. A large but very faint layer of stars surrounds the disk and bulge. In addition to stars, the Milky Way contains clouds of gas and dust called nebulae.
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.
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 main conclusion did the Herschels draw from their star counts?
The Milky Way is a disk of stars with the sun near the center.
10 interestering facts about the milky way?
The Milky Way, sometimes called simply the Galaxy, is the galaxy in which the Solar System is located. It is a barred spiral galaxy that is part of the Local Group of galaxies. It is one of billions of galaxies in the observable universe. See link for more information
In what disk of the Milky Way is your solar system located?
Our solar system is located in the thin disk of the Milky Way.
What is the milky way shaped like?
The milky way galaxy is a barred spiral shaped galaxy.
What is milky way best described as?
It is the SOLAR SYSTEM where the Earth is part of it( A Solar System Consists of Planets, Moon, Stars like SUN, Asteroids, Meteors, Comets and sometimes Black Hole).Above the surface of the Milky Way, Millions and Billions of Cluster of Stars are Scattered around it. A Cluster of Stars are made up of Looking-Young Stars but, They are actually old since the Milky Way was formed around 12 Billion Yrs. old.
