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 supermassive black holes at their centers will spiral alongside one another and ultimately merge, unleashing impressive gravitational waves throughout the universe. The result might be a single, substantial elliptical galaxy—occasionally termed “Milkomeda”—which will continue shining for trillions of a long time.
The name of our residence galaxy, like the names of a number of other astronomical objects, arrived from the ancient Greek and Roman cultures. Each the Greeks and Romans observed the starry band as being the river of milk.
Our have photo voltaic program, thus, really should be somewhat Protected as a result of reduced hazard of star collision. That said, we may possibly discover ourselves thrown into a very distinct route across the new galactic Middle since the merger pushes by.
The Milky Way is usually a galaxy, a colossal group of stars, dust, and gas that happen to be all held with each other by gravity. But what’s far more extraordinary is just how tremendous it is actually. Our Milky Way is about 100,000 light-a long time in diameter!
By way of example, observations of a three-way galactic collision in 2022 using the famed Hubble House Telescope gave some intriguing insights. The largest with the team, because it got into a decent orbit with one other two, snagged some materials with its reasonably much better gravity.
The Milky Way isn’t just large; it’s also wonderfully structured. It's got a flat, disk-like condition filled with billions of stars, which create spiral arms that wrap within the center. Consider an enormous spinning document, but in lieu of grooves, it has sparkling stars!
Starbirth, having said that, will accelerate because of the level of fuel staying pumped into our galaxy, producing our galaxy to brighten and for its inhabitants to grow in the approaching an incredible number of a long time adhering to the collision.

While Gaia sees fewer than one% of stars during the galaxy, astronomers can increase their conclusions and model the behavior of your complete Milky Way.
In Meteorologica, Aristotle (384–322 BC) states that the Greek philosophers Anaxagoras (c. 500–428 BC) and Democritus (460–370 BC) proposed which the Milky Way is the glow of stars indirectly obvious because of Earth's shadow, though other stars receive their mild with the Sun, but have their glow obscured by photo voltaic rays.[72] Aristotle himself believed that the Milky Way was A part of the Earth's upper atmosphere, together with the stars, and that it was a byproduct of stars burning that did not dissipate as a result of its outermost spot from the environment, composing its terrific circle.
There's also evidence that the Milky Way collided with quite a few smaller sized galaxies in the course of its evolution. In 2018, a staff of Dutch astronomers found a bunch of thirty,000 stars shifting in sync from the Solar's community in the other course mawinbet to the rest of the stars in the data set.
Telescopes enabled astronomers to distinguish the basic shape and structure of some of the closest galaxies prior to they realized they were being checking out galaxies.
