1 The Milky Way

2 What is the Milky Way? The Milky Way is the galaxy that contains our Solar System. Its name "milky" is derived from its appearance as a dim glowing band arching across the night sky whose individual stars cannot be distinguished by the naked eye.

3 Why is it called the Milky Way? Long ago, the Romans named the galaxy “via lactea,” which translates to “road of milk.” The Romans named it via lactea precisely because it looks like a milky patch of sky above the Earth at night. But, the Romans weren’t the first to name the galaxy. The Romans got the name from the Greeks, who called it galaxias kyklos, which translates into “milky circle.”

4 Who discovered the Milky Way?

5 How to go outside the Milky Way? To reach the center of the Milky Way Galaxy starting from the Earth, aim toward the constellation Sagittarius. If you were in a spacecraft, during the trip you would pass the stars in Sagittarius one by one (and many other stars!). Since we're inside the Milky Way Galaxy and we've never sent a spacecraft outside our Galaxy, we have no photographs of the Milky Way Galaxy.

6 How do you see the milky way? Any bright light source in the direction you look will diminish the view. Running out of a well-lit house, or jumping out of a car where you’ve spent the last 15 minute driving with the headlights on will make the Milky Way far less awesome.

7 Where are we in Milky Way? Our solar system is located in the outer reaches of the Milky Way Galaxy, which is a spiral galaxy. The Milky Way Galaxy contains roughly 200 billion stars. Most of these stars are not visible from Earth. Almost everything that we can see in the sky belongs to the Milky Way Galaxy.
