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 planet and the solar sys...
The Ancient Romans called it‘via lactea’which quite literally meant a ‘milky way/road’. Also, the word ‘galaxy’ is derived from a Greek word for ‘milk’. Although there is not absolute proof as to why they named our galaxy as something related to milk, some researchers believe what...

5.Why do astronomers believe that the Milky Way galaxy is interacting with another nearby galaxy? A. Star formation has increased in both galaxies. B. The two galaxies are slowly moving toward each other. C. A stream of gas and dust connects the two galaxies. ...
Every galaxy has a unique story to tell. The history of each one is evident in its shape. Scientists divide galaxies up into a handful of appearance-based categories. The Milky Way is what's known as a spiral galaxy, meaning that it looks like a broad, flattened disc with a slight bulg...
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...
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...
People have long called the band of light that appears to cross the sky by the name theMilky Waybecause of its appearance; it is the Milky Way from which our galaxy draws its name. That's as airtight and historically accurate as it gets people. ...
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 ...
What is the importance of the Michelson-Morley experiment? How would the use of dark matter affect the Earth and universe? Explain possiblities. Explain why it only appears that we are at the center of expansion of the universe and why an observer in another galaxy would see...
