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。
Considering that They can be not capable to end the gravitational collapse, they shrink to some gravitationally powerful object which can warp time and House around it much that mild no longer can escape.
Remnants of another, a bit younger, collision were spotted a 12 months later. The Milky Way proceeds devouring scaled-down galaxies to this day. A galaxy called Sagittarius (to not be mistaken With all the black hole) at present orbits close to the Milky Way and it has probable smashed by its disk quite a few moments in the past 7 billion several years.
We've got only started to check out the billions of planets it harbors. The behavior of Sagittarius A*, the procedures driving star development, and the last word destiny of the galaxy remain active frontiers of analysis.
Stars remain forming right now through the gas and dust that continue to be while in the disk. Star formation takes place most promptly while in the spiral arms.

If you propose to photograph the Milky Way and its Main, use instruments to visualise the galaxy’s situation from the sky after some time. Our advice could be the Ephemeris application, which predicts Milky Way visibility, its Main’s exact posture, and much more.
As items in Place stick to predictable trajectories, astronomers can reconstruct the paths of the stars billions of several years into the past and potential. Combining these reconstructed trajectories into just one stellar Film captures the evolution in the galaxy more than eons.
Astronomers observe another galaxies and Evaluate them Together with the habits on the one particular we are in. By way of example, whenever they calculated the velocities of stars and gasoline inside the Milky Way, they saw that an overall rotational movement differs from random motions. It is a attribute of the spiral galaxy.
The halo also holds streams of stars—the remains of dwarf galaxies torn apart by tidal forces since the Milky Way absorbed them.
Despite the fact that Exclusive relativity states that there's no "favored" inertial frame of reference in space with which to compare the Milky Way, the Milky Way does Have a very velocity with respect to cosmological frames of reference.[294]
The Milky Way Galaxy is made up of a thin disk containing mawinbet dust, gasoline, and young and outdated stars; a spherical halo made up of populations of very aged stars, and globular star clusters; a thick, more diffuse disk with stars which have Attributes intermediate concerning those in The skinny disk as well as halo; a peanut-formed nuclear bulge of generally aged stars throughout the Centre; and also a supermassive black hole within the quite Heart. The Sunshine is found roughly midway out on the Milky Way.
The Milky Way is not just where we live. It is exactly what we have been. And assuming that we look up for the evening sky, that river of light will carry on to encourage speculate, urging us to examine, to dream, and to do not forget that Within this vast, mysterious cosmos, Now we have always been dwelling.
A size comparison on the 6 major galaxies with the Neighborhood Team, including the Milky Way The Milky Way is among the two most significant galaxies inside the Neighborhood Group (another getting the Andromeda Galaxy), although the dimension for its galactic disc and the amount of it defines the isophotal diameter isn't effectively understood.
