Before Gaia, the largest dataset about positions and distances of stars from the Milky Way came from the mission known as Hipparcos, after an historical Greek astronomer who started charting the night time sky 150 decades in advance of Christ.
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。
Remnants of A further, somewhat youthful, collision were being noticed a year later. The Milky Way continues devouring more compact galaxies to today. A galaxy known as Sagittarius (not to be mistaken Together with the black gap) now orbits near the Milky Way and has probably smashed by its disk quite a few times prior to now 7 billion a long time.
Our personal solar process, consequently, must be relatively Protected due to the reduced chance of star collision. Having said that, we may perhaps discover ourselves thrown into a completely distinct path round the new galactic Heart given that the merger pushes through.
A study in 2020 concluded that Gaia detected a wobbling motion from the galaxy, which could be due to "torques from a misalignment of your disc's rotation axis with respect to the principal axis of the non-spherical halo, or from accreted make a difference in the halo acquired throughout late infall, or from close by, interacting satellite galaxies as well as their consequent tides".
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。
[237] With the discovery of the Sagittarius Dwarf Elliptical Galaxy arrived the invention of the ribbon of galactic debris because the polar orbit from the dwarf and its interaction Using the Milky Way tears it aside. On the 2004 discovery of a ring of galactic debris within an in-aircraft orbit throughout the Milky Way, it was at first thought that the particles was the remnant of a method dubbed the Canis Major Dwarf Galaxy.[238] Other Students thought it to become because of the Galactic warp,[239] a view that has been supported by More moderen evidence as of 2021.[240]
The Mayans noticed it for a celestial tree, while the Aboriginal peoples of Australia imagined it as a giant emu stretching throughout the heavens. These myths, born from curiosity and awe, ended up humanity’s to start with attempts to make sense from the glowing ribbon previously mentioned.
So subsequent time you look up at the stars, do not forget that you’re Portion of anything much larger and a lot more remarkable!
In 1610, Galileo built the main telescopic study in the Milky Way and identified that it is made up of a multitude of individual stars. Today, we are aware that the Milky Way comprises our look at inward of the huge cosmic pinwheel that we call the Milky Way Galaxy and that's our household.
Which means for folks living all-around 30° south latitude, the Milky Way’s Main appears almost instantly overhead — presenting a breathtaking view stuffed with vibrant stars and constellations full of gorgeous deep-sky objects.
You can find also proof which the Milky Way collided with various scaled-down galaxies through its evolution. In 2018, a staff of Dutch astronomers observed a bunch of thirty,000 stars relocating in sync throughout the Sunlight's neighborhood in the alternative way to the remainder of the stars in the information set.
Observations of distant galaxies reveal which the Universe experienced about a person-sixth as much baryonic (normal) issue as darkish make any difference when it absolutely was just a few billion many years previous. Even so, only about 50 % of those baryons are accounted for in the modern Universe according to observations of nearby galaxies just like the Milky Way.
Gaia facts at the moment mawinbet generates far more investigation papers than even the popular Hubble Room Telescope. Gaia will proceed charting the galaxy till a minimum of 2025, so long as the spacecraft continues to be in fantastic overall health, along with the catalog it has compiled will continue to keep astronomers fast paced for decades to come.
