First, let’s back up a bit and talk a bit about what the Milky Way actually is. Astronomers believe it is a barred spiral galaxy — a galaxy with a spiral shape that has a line of stars across its middle, as you can see in the picture above. If you were to fly across the gala...
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...
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...

The black hole at the center of the Milky Way, called Sag A*, is much less active than those at the center of other galaxies. A new study points to a simple answer: heat.Spotts, Peter N
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. ...
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...

It's possible not enough of their stars explode in supernovas. Some of the biggest, most intense regions of star formation are found in the smallest of galaxies, and scientists believe this is because stars reaching the ends of their lives in the so-called dwarf galaxies are more likely to...
humbling and powerful experiences we have as humans; it is a sight that has inspired us for tens of thousands of years. While the naked eye canseefewer than 4,500 stars at any given point on Earth, we know that there are at least 100 billion stars in the Milky Way (our galaxy) ...
