The Milky Way Galaxy is twisted in shape 银河系是弯的Astronomers have created the most precise map to date of the Milky Way—by tracking thousands of big pulsating stars spread throughout the galaxy, demonstrating that its disk of myriad(无数的) stars is not flat but dramatically warped and...
That portrayal could be wrong, however. A team of astronomers has published new research that suggests we have been wrong about the shape of the Milky Way for decades, with our galaxy instead having two main arms just like its contemporary spiral galaxies. Related:Milky Way galaxy: Everything ...

distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like spirals,too.In addition,still other galaxies are elliptical or irregular in shape. ...
Size and Shape of the Milky Way The Milky Way is a large barred spiral galaxy comprising an estimated 200 billion stars (some estimates range as high as 400 billion) arrayed in the form of a disk, with a central elliptical bulge (some 12,000 light-years in diameter) of closely packed ...
By determining the 3D coordinates of each distant pulsing star relative to the sun, the researchers built a large-scale 3D model of the Milky Way galaxy. The previous understanding of the spiral shape and structure of the Milky Way is built upon indirect measurements to celestial landmarks and...
What Type of Galaxy is the Milky Way? Barred spiral galaxy- The shape of the Milky Way galaxy is of barred spiral type. The stars that we see at night are part of it. The galaxy appears as a milky band of light in the sky, that's why it is called the Milky Way Galaxy. ...
Fathoming the shape of the Milky Way’s stellar halo, though, has long challenged astrophysicists for the simple reason that we are embedded within it. The stellar halo extends out several hundred thousand light years above and below the star-filled plane of our galaxy, where our Solar ...
Milky Way Galaxy - Structure, Dynamics, Stars: The first reliable measurement of the size of the Galaxy was made in 1917 by American astronomer Harlow Shapley. He arrived at his size determination by establishing the spatial distribution of globular clus
In 1955 the first detailed attempt to interpret the shape of the general van Rhijn luminosity function was made by the Austrian-born American astronomerEdwin E. Salpeter, who pointed out that the change in slope of this function nearMV= +3.5 is most likely the result of the depletion of the...
