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 final path of the Great Attractor and other galaxy clusters, including the Shapley Supercluster, guiding it.[297] The Regional Team, a cluster of gravitationally bound galaxies made up of, among Other individuals, the Milky Way plus the Andromeda Galaxy, is part of a supercluster known as the Local Supercluster, centered near the Virgo Cluster: Whilst they are relocating faraway from one another at 967 km/s (two,one hundred sixty,000 mph) as Component of the Hubble move, this velocity is less than might be predicted presented the 16.
Two spiral arms, the Scutum–Centaurus arm and also the Carina–Sagittarius arm, have tangent points inside the Solar's orbit about the center on the Milky Way. If these arms include an overdensity of stars when compared to the common density of stars while in the Galactic disk, It will be detectable by counting The celebrities near the tangent level.
The spiral arms from the Whirlpool Galaxy were being considered to are actually fashioned from the collision of a close-by galaxy. Would not or not it's odd for those who grew new arms whenever you collided into a thing?
A examine in 2020 concluded that Gaia detected a wobbling movement with the galaxy, which could be due to "torques from a misalignment in the disc's rotation axis with regard to the principal axis of the non-spherical halo, or from accreted make a difference in the halo obtained for the duration of late infall, or from nearby, interacting satellite galaxies as well as their consequent tides".

These observations, honored Together with the 2020 Nobel Prize in Physics, confirmed that supermassive black holes are not merely theoretical—They're serious, cosmic engines lurking inside the centers of galaxies like ours.
We're little by little Understanding more about Sagittarius A* by means of initiatives such as the very first-ever picture with the black gap, which was obtained on Could twelve, 2022. The graphic captured faint quantities of mild attributable to heated matter shifting Tremendous-speedy in the direction of the middle in the black gap; the graphic is really a superior-definition shadow.
If you're Fortunate mawinbet enough to become someplace in which the sky is incredibly, incredibly darkish, you'll see the Milky Way—massive, majestic, and dominating the night time sky. Most civilizations have stories to elucidate how the Milky Way arrived to exist. So exactly what is the story present day astronomy tells of how the Milky Way formed?

While Exclusive relativity states that there is no "favored" inertial frame of reference in space with which to compare the Milky Way, the Milky Way does Possess a velocity with respect to cosmological frames of reference.[294]
In summary, the Milky Way is a huge, beautiful, and mysterious galaxy that’s home to billions of stars, including our own Sunshine. It’s so huge that it’s difficult to grasp its true dimensions, but something is obviously: once we gaze up within the evening sky, we’re only viewing a very small portion of this remarkable cosmic entity.
The halo extends far further than the obvious disk, progressively thinning in to the intergalactic medium, but it consists of a sizable portion of the Milky Way’s unseen dim subject.
In January 2006, scientists documented which the heretofore unexplained warp while in the disk from the Milky Way has now been mapped and located to become a ripple or vibration arrange by the big and Compact Magellanic Clouds because they orbit the Milky Way, producing vibrations whenever they go through its edges.
