A massive disk of fuel all over Sagittarius A* billows out so far as five to thirty gentle-decades from your supermassive black hole. It is this massive, but tenuous, area of gasoline that provides somewhat of material for Sagittarius A* activity.
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。
The spiral-formed Milky Way belongs to the very first type; if you may see it from the best (or The underside), it could seem like a spinning pinwheel.
With strong telescopes, radio observations, and House missions like Gaia, we now map billions of stars and trace the framework of our galactic home with unprecedented precision.
Numerous stars are ancient, relationship again practically on the start on the galaxy. These Populace II stars, located in the halo and globular clusters, consist of only a few heavy aspects, having fashioned prior to supernovae enriched the galaxy with metals.
在內華達州不受光汙染的黑岩沙漠看見的在人馬座方向上的銀河（包括銀河中心）。在右下方是天蠍座，位於心宿二上方的亮星是木星。
These observations, honored with the 2020 Nobel Prize in Physics, confirmed that supermassive black holes are not merely theoretical—They are really authentic, cosmic engines lurking in the facilities of galaxies like ours.
Earlier, both of these galaxies, at close to 2% in the mass on the Milky Way, ended up viewed as also little to impact the Milky Way. Nevertheless, in a pc model, the movement of both of these galaxies generates a dark subject wake that amplifies their influence within the much larger Milky Way.[290]
The radius measurement is extremely unsure, as a few of the material bordering the Earth might be masquerading as remaining Section of the Earth alone.
Our galaxy is on a gradual, unavoidable collision training course with Andromeda. In about four billion yrs, the two spirals will merge inside a titanic cosmic dance.
Whilst Unique relativity states that there is no "desired" inertial frame of reference in Place with which to match the Milky Way, the Milky Way does Have a very velocity with respect to cosmological frames of reference.[294]
A simulation released in 2011 suggested which the Milky Way can have acquired its spiral arm structure due to recurring collisions With all the Sagittarius Dwarf Elliptical Galaxy.[226]
The galaxy will endure lengthy right after our species is gone, continuing its slow dance throughout mawinbet the universe, forging new stars and worlds, carrying forward the matter that once lived as us.
The movement sample matched what researchers had previously observed in Laptop simulations of galactic collisions. These stars also differed in colour and brightness, which instructed they arrived from a unique galaxy.
