Why Is Our Galaxy Called the Milky Way? The truth is that nobody knows who exactly is responsible for giving the galaxy its name, but there is plenty of evidence as to how the name evolved. What is known is that
This would be an example of our human-centered biases. Although many of them do resemble the Milky Way, others come in wildly different shapes and forms. You've probably seen illustrations of our home galaxy hanging on the walls in countless science classrooms. But we bet you didn't know ...
Our galaxy, the Milky Way, is shaped like a flat disk surrounding a central bulge. 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 ...

There are more than 200 billion (十亿) stars in our galaxy, called the Milky Way, and our Sun is only one of them. But scientists have discovered many other galaxies in the universe. They are a long way away and their light has travelled for many years to reach u...
We must distinguish, at this point, between two different stellar types: Population I and Population ll, the latter being much older than the former. These groups can also be distinguished by their locations. Our galaxy, the Milky Way, is shaped like a flat disk surrounding a central bulge....
The real reason it looks yellow relates to how our eyes sense light. Before we get into that, however, let's look at what color the sky actually is. Blue Skies: The Size Is the Limit The Science Behind the Blue Sky Like bananas, atoms, molecules and particles in the atmosphere ...
exchange gas and dust, but don’t actually collide.Many astronomers believe that the trail of gas and dust that stretches from our Milky Way Galaxy to one nearby is the result of an interaction when the gravitational forces of the Milky Way pulled some dust and gas off the other galaxy. ...
When the monster back hole at the center of the Milky Way galaxy belched out an exceptionally high number of powerful X-ray flares last year, it made astronomers wonder — is this a sign that the beast chowed down on a passing gas cloud, or is this lack of cosmic etiquette typical for...
the elliptical galaxy and stirred up all the stars like a hornet's nest. But these random motions can dominate in disk galaxies, too. This is strange, since stars in adisk galaxyform in a narrow, gas-rich plane called the "thin disk." Indeed, our Milky Way galaxy has a thin disk, ...
