How to see the Milky Way?

Under a clear, moonless and empty night sky, you will see the splendor of the galaxy.

Last fall is one of the most favorable times of the year to admire the splendor of the galaxy.

That "silver river" was clearly visible on moonless nights all over the world. Recently, however, many people are unable to observe because living in places where light pollution is caused by night lights in the city, MMN said.

Want to see it, people need to go away from the city, to the countryside, even to a wild area as possible. Even in the countryside, there are many appliances, bright lights shining into the night sky.

The days when cold air passed, the sky became the clearest. Viewers need to stand for a while in the night sky to allow their eyes to fully adapt to the darkness. About 20 minutes later, the human eye senses the faint light from the stars.

So how does the galaxy appear? It is not like any image on the Internet because it is taken from a camera with special light-gathering mechanisms, something that cannot be done by the human eye. What you see is a faint white, light streak, stretching into a huge arc from the south to the northeast horizon, looking closely like speckled dots, like a fluffy cloud. . There are brighter areas, especially the central part of the galaxy near the south of the sky, and much darker, where interstellar dust clouds block light beyond.

The dark Coalsack Nebula is located next to Deneb star in the constellation Cygnus. Just below the star Deneb is one of the brightest parts of the northern Milky Way galaxy, which is the North American nebula because its image closely resembles the North American continent. Within the northern range of the Milky Way are the constellations Cassiopeia and Perseus, the stars are less dense when looking at the constellation Sagittarius.

The observer will not be able to see any color with the naked eye or with binoculars in the Milky Way. Photos can show the red light of hydrogen gas, but the light is too dim to activate color-sensing components in the human eye, so we see them all in shades of gray. .
