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。
Astonishing 'halo' of large-Electricity particles all over huge galaxy cluster can be a glimpse to the early universe
The black hole during the Milky Way known as Sagittarius A*. The black hole is usually dormant, which makes it incredibly demanding to look at. Sagittarius A* features a mass four.3 million instances that in the sun, astronomers Reinhard Genzel and Andrea Ghez found it in 2008.
But folktales vary from lifestyle to tradition: one particular East African tribe considered the hazy band given that the smoke of historic campfires, numerous Native American tales explain to of a path across the sky traveled by sacred animals, As well as in Siberia, the diffuse arc was called the seam of your tent in the sky.

This 200-light-weight-year-huge composition could possibly be feeding our galaxy's Centre: 'No one had any concept this cloud existed'
Together with the stellar halo, the Chandra X-ray Observatory, XMM-Newton, and Suzaku have furnished evidence that there's also a gaseous halo that contains a great deal of very hot gas. This halo extends for hundreds of A huge number of gentle-a long time, much farther as opposed to stellar halo and close to the space of the massive and Little Magellanic Clouds.
Starbirth, nonetheless, will speed up on account of the level of fuel getting pumped into our galaxy, leading to our galaxy to brighten and for its inhabitants to extend in the coming a lot of yrs following the collision.
We now are aware that the Milky Way resides inside the Nearby Group of galaxies, produced up of above thirty galaxies which include Andromeda, Triangulum and Leo I to name but several. It seems that It really is very good to find out who your neighbors are, as They could be closer than you believe.
Proof on the Milky Way consisting of many stars came in 1610 when Galileo Galilei utilised a telescope to review the Milky Way and identified that it had been composed of an enormous amount of faint stars. Galileo also concluded that the looks from the Milky Way was resulting from refraction in the Earth's ambiance.[eighty][81][seventy three] In the treatise in 1755, Immanuel Kant, drawing on earlier operate by Thomas Wright,[eighty two] speculated (effectively) that the Milky Way could be a rotating overall body of an enormous quantity of stars, held with each other by gravitational forces akin for the Solar System but on much bigger scales.
In keeping with current experiments, the Milky Way as well as the Andromeda Galaxy lie in what while in the galaxy coloration–magnitude diagram is recognized as the "eco-friendly valley", a region populated by galaxies in changeover through the "blue cloud" (galaxies actively forming new stars) for the "crimson sequence" (galaxies that deficiency star development). Star-development exercise in environmentally friendly valley galaxies is slowing because they operate out of star-forming fuel during the interstellar medium.
Just as Earth orbits the Solar, the solar technique orbits the middle of your Milky Way. Inspite of hurtling via space at speeds of all around 515,000mph (828,000kmph) our photo voltaic system usually takes somewhere around 250 million yrs to complete a single revolution, In accordance with Appealing Engineering.
A supermassive black hole is located at the center in the Galaxy. Measurements on the velocities of stars Positioned inside of a number of mild-days of the center exhibit which the mass inside of their orbits within the Middle is about four.
In January 2006, scientists documented the heretofore unexplained warp while in the disk of your Milky Way has now been mapped and located to become a ripple or vibration arrange by the massive and Tiny Magellanic Clouds as they orbit the Milky Way, resulting in vibrations once they มาวินเบท go through its edges.
