When we look to the edge, we see a spiral arm of the Milky Way known as the Orion-Cygnus Arm (or the Orion spur): a river of light across the sky that gave rise to so many ancient myths. The solar system is just on the inner edge of this spiral arm.
What part of the Milky Way are we looking at?
We're about 26,000 light-years from the center of the galaxy, on the inner edge of the Orion-Cygnus Arm . It's sandwiched by two primary spiral arms, the Sagittarius and Perseus Arms.
What do you see when you see the Milky Way?
When you observe the night sky with your eyes, you can see the Moon, perhaps several planets, and many stars . If you are in a particularly dark location and if the moonlight is not too bright, you may also see a faint band of light that stretches from horizon to horizon.
What does the Milky Way look like when viewed from Earth?
The Milky Way is visible from Earth as a hazy band of white light, some 30° wide, arching the night sky . ... Dark regions within the band, such as the Great Rift and the Coalsack, are areas where interstellar dust blocks light from distant stars. The area of sky that the Milky Way obscures is called the Zone of Avoidance.
How does the human eye see the Milky Way?
With our own eyes, the Milky Way looks nowhere near as detailed or colourful as some of the photos I share. The reason for this is our eyes are not as sensitive as a digital camera sensor and they collect less light , meaning we see less detail in the Milky Way.
Can I see Milky Way today?

How old is our galaxy?
Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old . The newest galaxy we know of formed only about 500 million years ago.
How many Milky Ways are there?

Does the Milky Way look like?
The Milky Way is a spiral galaxy . ... The spiral arms contain stars, cold molecular gas, glowing star- forming regions and dark dust. The galactic bulge contains mainly older stars, and appears redder than the spiral arms. Since the central bulge is elongated, the Milky Way is classified as a barred spiral galaxy.
Why is the Milky Way white?
“The true color of the Milky Way is as white as fine-grained new spring snow seen in early morning light ,” said Dr. ...

This is what you would see if your color vision worked in dim light.
Can you see the colors of the Milky Way with your eyes?
One thing you won't see in the Milky Way, either in binoculars or with the naked eye, is any color . Photographs register the reddish glow of hydrogen gas, but the light is too faint to trigger the color receptors in the human eye, so all you'll see are shades of gray.
