As we stare upon the Milky Way’s glowing band, we have been seeking into a mirror, looking at the framework that gave us existence. It reminds us that we are fleeting, yet Element of a thing eternal.
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。
Traveling inward toward the galactic Centre, stellar density would boost dramatically. Stars would crowd alongside one another, orbiting swiftly during the deeper gravitational very well. Clouds of dust and gas would obscure Considerably of The sunshine, forming dark lanes that weave throughout the spiral arms.
At the time a white dwarf is formed, it begins to go through radiative cooling and the surface temperature steadily drops. By measuring the temperatures of The best of those white dwarfs and evaluating them for their envisioned Original temperatures, an age estimate may be manufactured.
Despite hundreds of years of research, the Milky Way still retains mysteries. We do not fully have an understanding of darkish make a difference, nor the detailed heritage of how the galaxy shaped.

To generally be a lot more precise, the Milky Way is really a barred spiral galaxy, meaning it has a central bar-shaped straight framework made up of stars.
Our galaxy is on the slow, inevitable collision training course with Andromeda. In about four billion many years, the two spirals will merge inside a titanic cosmic dance.
Though Exclusive relativity states that there's no "preferred" inertial frame of reference in Room with which to check the Milky Way, the Milky Way does Have got a velocity with regard to cosmological frames of reference.[294]
However Inspite of our scientific expertise, standing under the Milky Way even now evokes primal awe. Its arc of light reminds us that we have been part of a thing huge and historic, connected to stars that lived and died ahead of Earth existed. Searching up, we sense the echo of every human who ever puzzled what lies beyond.
The galaxy will endure very long just after our species is absent, continuing its sluggish dance with the universe, forging mawinbet new stars and worlds, carrying forward the matter that when lived as us.
Over and above the thin disk from the galaxy lies the halo, a vast spherical location populated by historical stars and globular clusters—dense, spherical swarms of approximately a million stars orbiting like satellites around the galactic Centre.
