世界各地有許多創造天地的神話圍繞著銀河系發展出來。很特別的是，在希臘就有兩個相似的希臘神話故事在解釋銀河是怎麼來的。有些神話將銀河和星座結合在一起，認為成群牛隻的乳液將深藍色的天空染白了。在東亞，人們相信在天空中群星間的霧狀帶是銀色的河流，也就是所謂天河。
The Milky Way is relocating in the overall way of The nice Attractor along with other galaxy clusters, including the Shapley Supercluster, driving it.[297] The Area Team, a cluster of gravitationally sure galaxies made up of, among Other individuals, the Milky Way along with the Andromeda Galaxy, is a component of a supercluster called the Community Supercluster, centered close to the Virgo Cluster: Whilst they are moving away from each other at 967 km/s (two,a hundred and sixty,000 mph) as Element of the Hubble move, this velocity is less than would be expected specified the sixteen.
The black gap while in the Milky Way is named Sagittarius A*. The black hole is mostly dormant, that makes it incredibly demanding to watch. Sagittarius A* features a mass 4.three million situations that on the Sunlight, astronomers Reinhard Genzel and Andrea Ghez found out it in 2008.
With impressive telescopes, radio observations, and Area missions like Gaia, we now map billions of stars and trace the structure of our galactic household with unparalleled precision.
The Milky Way can be a galaxy, a colossal team of stars, dust, and fuel which are all held with each other by gravity. But what’s a lot more remarkable is just how enormous it is. Our Milky Way is about a hundred,000 light-weight-yrs in diameter!
If you reside earlier mentioned 55ºN latitude, you will not see your entire Galactic Center. You’ll capture only Portion of the Main, and the best time is right before and just after summer months.

But reconstructing the shape and framework of our very own galactic house was sluggish and tiresome. The procedure involved constructing catalogs of stars, charting their positions in the sky and deciding how far from Earth They can be.
Like early explorers mapping the continents of our globe, astronomers are chaotic charting the spiral construction of our galaxy, the Milky Way. Applying infrared photos from NASA's Spitzer House Telescope, scientists have found that the Milky Way's stylish spiral construction is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was believed to possess four key arms.
This bar includes the galaxy’s nucleus in the middle and has two spiral arms attached to its finishes. When mawinbet the Milky Way was a standard spiral galaxy, its arms would direct ideal to its center (or nucleus) like while in the Andromeda Galaxy.
This established an intriguing streak of gas, dust as well as other resources flowing in the larger sized galaxy, seen even from Earth.
Up coming comes the Picture shoot. Generally speaking, make use of a tripod, set your products to get a timelapse method and be ready to experiment with different focuses and diverse lenses. For novices, we also have a complete tutorial on how to photograph the Milky Way.
The middle location from the Milky Way is called the Galactic Heart, and it contains a supermassive black gap of about four million photo voltaic masses referred to as Sagittarius A*. To begin to see the black gap, you’ll have to have a Unique radio telescope.
