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 Andromeda Galaxy is the Milky Way's twin. It is really the closest galaxy that is definitely an identical sizing and form. In several billion yrs, the two galaxies will collide and type one particular more substantial elliptical galaxy - Milkomeda.
Remnants of Yet another, a bit youthful, collision ended up spotted a 12 months afterwards. The Milky Way continues devouring smaller sized galaxies to at the present time. A galaxy termed Sagittarius (never to be mistaken Using the black hole) presently orbits close to the Milky Way and has most likely smashed via its disk a number of situations previously seven billion several years.
The Andromeda galaxy, our nearest neighbor, is twice as massive. There are actually even some galaxies in existence that happen to be in excess of 30 occasions larger when compared to the Milky Way!
All of that may be surrounded by a spherical halo of dust and gasoline, which is twice as extensive given that the disk. Astronomers feel that the entire galaxy is embedded in an even greater halo of invisible dim issue.
They may be relics through the Milky Way’s youth, survivors from an period when smaller sized protogalaxies merged to create the trendy Milky มาวินเบท Way.
If you can, get to your web site while in the daytime as you'll likely choose to scout the area for the best angles. Great Milky Way images have a tendency to make full use of the landscape in Innovative approaches, so try to find exciting and well known all-natural characteristics like mountains, boulders or rock designs.
Applying Gaia knowledge, experts discovered that these collisions triggered durations of powerful star development during the Milky Way and may even have a thing to carry out Along with the galaxy's trademark spiral shape. The study implies that our Sunshine was born through a kind of durations some 4.six billion decades ago.
The radius measurement is very unsure, as several of the fabric surrounding the planet can be masquerading as currently being A part of the planet by itself.
The halo also holds streams of stars—the remains of dwarf galaxies torn apart by tidal forces as being the Milky Way absorbed them.
This bar incorporates the galaxy’s nucleus in the middle and it has two spiral arms connected to its finishes. In case the Milky Way was a standard spiral galaxy, its arms would direct appropriate to its Middle (or nucleus) like within the Andromeda Galaxy.
There exists also evidence the Milky Way collided with quite a few smaller galaxies for the duration of its evolution. In 2018, a group of Dutch astronomers found a bunch of 30,000 stars shifting in sync from the Sunlight's neighborhood in the other course to the rest of the stars in the information set.
古代的亞美尼亞神話稱銀河系為麥稈賊之路，敘述有一位神祇在偷竊麥稈之後，企圖用一輛木製的運貨車逃離天堂，但在路途中掉落了一些麥稈。
On one particular aspect of The controversy, Shapley considered the Milky Way was much bigger than preceding estimates and that we weren't at the center. He also claimed that "spiral nebulae" like Andromeda had been a Section of the Milky Way.
