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。
About forty% of your Milky Way's clusters are on retrograde orbits, meaning they transfer in the alternative route in the Milky Way rotation.[232] The globular clusters can stick to rosette orbits concerning the Milky Way, in contrast into the elliptical orbit of a planet all-around a star.[233]
In Greek mythology, Zeus destinations his son born to some mortal female, the toddler Heracles, on Hera's breast even though she is asleep so the infant will drink her divine milk and develop into immortal. Hera wakes up though breastfeeding and then realizes she's nursing an not known infant: she pushes the baby absent, a number of her milk spills, and it produces the band of sunshine known as the Milky Way.
雖然從非常久遠的古代，人們就認識銀河。但是對銀河系的真正認識還是從近代才開始。
Previously, experts assumed that these arms were being key, but with the assistance of infrared visuals from NASA's Spitzer Room Telescope, they identified normally.
Because dark make any difference will not emit any light-weight, its presence can only be inferred indirectly by its gravitational outcomes within the motions of stars inside the galaxy. Calculations advise that this puzzling stuff can make nearly ninety% of your galaxy's mass.
[237] With the invention of your Sagittarius Dwarf Elliptical Galaxy arrived the discovery of the ribbon of galactic particles as being the polar orbit with the dwarf and its conversation Together with the Milky Way tears it apart. Upon the 2004 discovery of a hoop of galactic particles in an in-aircraft orbit around the Milky Way, it had been originally thought that the particles was the remnant of the program dubbed the Canis Key Dwarf Galaxy.[238] Other scholars believed it for being a result of the Galactic warp,[239] a view that has been supported by Newer proof as of 2021.[240]

Finding out the Milky Way was notoriously complicated. Astronomers sometimes Evaluate the effort to attempting to describe the dimensions and framework of the forest when being dropped in the midst of it. From our situation on Earth, we just lack an overview.
In 1610, Galileo made the main telescopic survey of the Milky Way and learned that it's composed of a multitude of particular person stars. Nowadays, we realize that the Milky Way comprises our see inward of the massive cosmic pinwheel that we phone the Milky Way Galaxy and that is our household.
However, if you might mawinbet gaze by way of a telescope, that faint glow would resolve into tens of millions upon countless stars. You would be on the lookout into the center from the Milky Way—our property galaxy, the grand island of stars where our Solar and Earth reside.
But despite our scientific know-how, standing under the Milky Way continue to evokes primal awe. Its arc of light reminds us that we've been Section of a little something wide and historical, linked to stars that lived and died ahead of Earth existed. Hunting up, we really feel the echo of each human who at any time wondered what lies further than.
Close to this black gap, stars dance in a posh gravitational ballet. Some full orbits in just some decades, transferring so fast that their paths have offered immediate evidence in the black gap’s existence.
A sizing comparison of the 6 biggest galaxies in the Neighborhood Group, including the Milky Way The Milky Way has become the two major galaxies during the Local Group (the opposite getting the Andromeda Galaxy), although the dimensions for its galactic disc and the amount of it defines the isophotal diameter isn't well comprehended.
