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] may be the galaxy that features the Photo voltaic System, With all the identify describing the galaxy's look from Earth: a hazy band of light witnessed during the night sky shaped from stars in other arms from the galaxy, that are so far-off that they can't be individually distinguished through the naked eye.
To provide you with an notion of what Meaning, a lightweight-year is the distance that light can travel in one year, that's around 5.88 trillion miles. So, for those who multiply that by 100,000, you’d get the gap throughout our Milky Way galaxy. That’s a amount so substantial it’s hard to even consider!
But folktales vary from tradition to lifestyle: a single East African tribe thought of the hazy band since the smoke of historical campfires, various Indigenous American tales tell of the path throughout the sky traveled by sacred animals, As well as in Siberia, the diffuse arc was often called the seam of your tent from the sky.
This observation indicates the Milky Way possesses only two major stellar arms: the Perseus arm as well as the Scutum–Centaurus arm. The rest of the arms consist of excessive gas but not excess old stars.[213] In December 2013, astronomers identified the distribution of younger stars and star-forming areas matches the 4-arm spiral description from the Milky Way.
This 200-light-weight-12 months-huge composition could be feeding our galaxy's center: 'Nobody had any thought this cloud existed'
[237] With the invention from the Sagittarius Dwarf Elliptical Galaxy arrived the invention of the ribbon of galactic particles as being the polar orbit on the dwarf and its interaction Using the Milky Way tears it apart. On the 2004 discovery of a ring of galactic particles in an in-plane orbit around the Milky Way, it absolutely was in the beginning thought that the debris was the remnant of the system dubbed the Canis Main Dwarf Galaxy.[238] Other scholars thought it to get due to the Galactic warp,[239] a see which has been supported by Newer proof as of 2021.[240]
The gaseous distribution within the Galaxy’s disk has two main spiral arms that arise from your ends of the central bar, in conjunction with many fainter arms and brief spurs; the Sunshine is located in a type of spurs.
We now understand that the Milky Way resides within the Area Team of galaxies, manufactured up of above 30 galaxies which includes Andromeda, Triangulum and Leo I to name but a couple of. It seems that It can be very good to learn who your neighbors are, as they may be nearer than you think that.
In 1610, Galileo made the main telescopic study on the Milky Way and found out that it is made up of a multitude of specific stars. These days, we recognize that the Milky Way comprises our check out inward of the massive cosmic pinwheel that we contact the Milky Way Galaxy and that's our home.
Within it lie tales older than Earth itself—tales of start and death of stars, of mysterious invisible issue, of the monstrous black gap lurking silently at its Middle. To understand the Milky Way is to grasp where we come from and in which we're going.
On a clear night time, void of sunshine pollution, we can capture a glimpse of the brilliant lights on the galactic city streaking across the evening sky. Our window in the universe, this milky white band of stars, dust and fuel is where our galaxy gets its name.
A diagram of your Solar's location in the Milky Way; the angles signify longitudes within the galactic coordinate technique A galactic quadrant, or quadrant from mawinbet the Milky Way, refers to at least one of four round sectors inside the division of the Milky Way.
The motion sample matched what experts experienced previously witnessed in Laptop or computer simulations of galactic collisions. These stars also differed in color and brightness, which advised they arrived from a unique galaxy.
