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。
If we had been to travel inwards toward the city center, we'd find the Scutum-Centaurus and Norma arms.
The Milky Way is a considerable spiral-formed technique of approximately four hundred billion stars, including our Sunlight, bound jointly by gravity. The Area between stars is mostly filled with dust and fuel, and while in the pretty coronary heart of This method lies a supermassive black hole. This system known as a “galaxy”.
[127] A more recent 2018 paper later rather ruled out this hypothesis, and supported a conclusion the Monoceros Ring, A13 and TriAnd Ring have been stellar overdensities instead kicked out from the principle stellar disk, Along with the velocity dispersion of your RR Lyrae stars uncovered to be higher and consistent with halo membership.[128]
This cosmic recycling is accountable for each individual atom within our bodies heavier than hydrogen. The iron in your blood, the calcium within your bones, the oxygen you breathe—they were all solid in stars that lived and died long prior to the Solar was born. In an extremely real feeling, we are made with the galaxy itself.

Gaia steps the exact positions and distances of more than one billion stars, together with their mild spectra, which permits researchers to understand The celebs' composition and age, Based on ESA. The posture details let astronomers to determine the speeds and directions in which The celebs shift in Area.
The grey strains radiating from the Sunshine's posture (upper center) list the three-letter abbreviations from the corresponding constellations
Our Solar can be an unremarkable yellow G-variety star—normal in comparison with a lot of its neighbors. However stars such as the Sun are crucial, secure plenty of to permit planets to sort and existence to emerge.
Although Gaia sees under one% of stars from the galaxy, astronomers can expand their results and design the habits of all the Milky Way.
We can not see it, but its gravity styles the rotation of stars and retains the galaxy with each other. Without darkish make any difference, the Milky Way would merely fly apart.
Nonetheless Regardless of our scientific information, standing beneath the Milky Way still evokes primal awe. Its arc of light reminds us that we are part of one thing huge and historic, linked to stars that lived and died right before Earth existed. On the lookout up, we experience the echo of each human who ever wondered what lies past.
A supermassive black hole is situated at the center on the Galaxy. Measurements of the velocities of stars Situated within a number of light-days of the middle show the mass inside of their orbits around the Middle is about four.
The Milky Way is not merely an enormous, attractive galaxy; it’s also full of mysteries waiting around being solved. By way of example, มาวินเบท though we know it’s a spiral galaxy, we’re unsure what number of spiral arms it's got simply because we’re within it and might’t see its whole structure.
