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。
依據希臘神話，銀河是赫拉在發現宙斯以欺騙的手法誘使他去餵食年幼的赫拉克勒斯因而濺灑在天空中的奶汁。另一種說法則是赫耳墨斯偷偷地將赫拉克勒斯帶去奧林匹斯山，趁著赫拉沉睡時偷吸她的奶汁，而有一些奶汁被射入天空，於是形成了銀河。
At the middle with the Milky Way sits a supermassive black gap named Sagittarius A*. With a mass equivalent to that of four million suns, the black hole, discovered in 1974, may be observed from the sky with radio telescopes close to the constellation Sagittarius.
With potent telescopes, radio observations, and Room missions like Gaia, we now map billions of stars and trace the construction of our galactic residence with unparalleled precision.
In spite of centuries of examine, the Milky Way nevertheless holds mysteries. We do not fully understand darkish issue, nor the in-depth historical past of how the galaxy fashioned.

The final time our World was in this place, dinosaurs ended up just emerging and mammals have been still to evolve.
In 2022, we imaged this glutton with the core of our galaxy for the pretty to start with time, as a result of an impressive approach letting us to view the shadow of the black gap.
Being far more precise, the Milky Way is usually a barred spiral galaxy, which suggests it's got a central bar-formed straight structure made up of stars.
However this shimmering gentle is much more than just a visible marvel. It's really a cosmic town spanning 100 thousand light-weight-years, made up of many billions of stars, swirling collectively inside a graceful spiral certain by gravity and formed by forces we're only commencing to grasp.
Based on the latest research, the Milky Way plus the Andromeda Galaxy lie in what during the galaxy coloration–magnitude diagram is named the "environmentally friendly valley", a location populated by galaxies in changeover with the "blue cloud" (galaxies actively forming new stars) into the "pink sequence" (galaxies that lack star formation). Star-formation activity in environmentally friendly valley galaxies is slowing as they run away from มาวินเบท star-forming fuel while in the interstellar medium.
There exists also proof that the Milky Way collided with a number of scaled-down galaxies during its evolution. In 2018, a group of Dutch astronomers located a group of 30,000 stars moving in sync from the sun's community in the other way to the rest of the stars in the info established.
Because the time with the dinosaurs, We've concluded only only one lap. Civilization itself has lasted less than a blink in galactic time. The Milky Way is not merely an area we live in—it is an enduring, historic home which includes existed very long ahead of humans and may keep on lengthy after we have been gone.
Gaia details now generates extra study papers than even the popular Hubble House Telescope. Gaia will carry on charting the galaxy until eventually at least 2025, provided that the spacecraft stays in fantastic health and fitness, and also the catalog it's compiled will preserve astronomers fast paced for decades to come.
