GALAXIES (星系) OF THE UNIVERSE The Milky Way is only one galaxy among a few hundred million galaxies in our universe (each with hundreds of billions of stars).Galaxies are huge groupings of stars, planets, gas and dust. Our sun is in the Milky Way, which measures about 100,000 light...
For years, scientists have relied on the Milky Way to understand how galaxies form. However, new research suggests our galaxy might not be a typical example of how galaxies evolve in the universe. “The Milky Way has been an incredible physics laboratory, including for the physics of galaxy f...

If the Universe Is Expanding, Why Are the Milky Way and Andromeda Galaxies on a Collision Course? [Video]Eric R. Olson
You've probably seen illustrations of our home galaxy hanging on the walls in countless science classrooms. But we bet you didn't know that those posters are proportionately thicker than a key component of the galaxy itself. That's right. Like a fried egg, the Milky Way consists of a cent...
The sun and its planets 7 the solar system. And our solar system is a small part of a much larger group of stars and planets, called the Galaxy or the Milky Way. There are billions of stars in the Galaxy, and our sun is only one of them. ...
The Milky Way is only one galaxy among a few hundred million galaxies in our universe (each with hundreds of billions of stars). Galaxies are huge groupings of stars, planets, gas and dust. Our sun is in the Milky Way, which measures about 100,000 light years across. That long thin ...
The sun and its planets are called the solar system, and our solar system is a small part of a larger group of stars and planets, called the Galaxy or the Milky Way. There are stars in the Galaxy, and our sun is only one of them. Scientists have also discovered many other galaxies ...
Whereas Population I stars are found mainly in the galactic disk, Population II stars mostly reside in the central bulge of the galaxy and in the halo surrounding this bulge.Population II stars date to the early stages of the universe. Formed when the cosmos was filled with hydrogen and ...
What Is the Milky Way? The Milky Way is a barred spiral galaxy formation that is typical of many other galaxies in the Universe. It is neither the largest nor the oldest galaxy out there. But it is of particular significance to us human beings because it just happens to include both the...
