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。
The Milky Way or Milky Way Galaxy[c] will be the galaxy that includes the Photo voltaic Program, With all the title describing the galaxy's visual appearance from Earth: a hazy band of light viewed from the night time sky fashioned from stars in other arms with the galaxy, which happen to be so far-off that they can't be individually distinguished through the naked eye.
Remnants of A further, marginally youthful, collision were being noticed a calendar year later on. The Milky Way continues devouring smaller galaxies to today. A galaxy identified as Sagittarius (to not be mistaken Using the black hole) at the moment orbits near to the Milky Way and it has possible smashed through its disk a number of situations in past times 7 billion years.
With potent telescopes, radio observations, and House missions like Gaia, we now map billions of stars and trace the framework of our galactic house with unparalleled precision.
Experts would really like to have additional details about this supermassive black gap to determine more about how it had been shaped as well as conditions that manufactured its development achievable.
Want to examine how light-weight-polluted the sky in the town is? Drop by our infographic and explore how light-weight air pollution influences Everything you see!
Significantly above and under the galactic disk lies the halo, a sparse but huge location that contains historical stars and globular clusters. Some of these clusters are over 12 billion years aged, virtually as previous because the universe alone.
If you can rise substantial higher than the Milky Way and glance again upon it, you'll see a shocking barred spiral galaxy—its central bar glowing warmly with tightly packed stars, its majestic arms curling outward like cosmic ribbons.
Astronomers observe one other galaxies and Review them Along with the conduct from the one we are now living in. One example mawinbet is, every time they calculated the velocities of stars and gasoline within the Milky Way, they observed that an Over-all rotational motion differs from random motions. This is a attribute of a spiral galaxy.
It might seem to be modest from our point of view, nonetheless it’s a massive, sprawling entity which makes our photo voltaic system look like a speck of dust. Let’s take a better evaluate just how big the Milky Way really is.
We can't see it, but its gravity designs the rotation of stars and retains the galaxy together. Without having dim matter, the Milky Way would just fly aside.
On clear evenings, when the moon hides and metropolis lights are far-off, the heavens unveil anything breathtaking—an arch of pale, misty mild stretching across the sky. On the bare eye, it looks like a ghostly cloud, a tender brushstroke throughout the cosmic canvas.
Nebulae, sculpted by radiation and stellar winds, shade the arms in fantastic pinks and purples. Supernovae punctuate this stellar tapestry with bursts of sunshine and energy, recycling hefty factors into Room to sort long run generations of stars and planets.
Further than the thin disk in the galaxy lies the halo, an enormous spherical location populated by historic stars and globular clusters—dense, spherical swarms of up to a million stars orbiting like satellites throughout the galactic Centre.
