Milky Way Galaxy - Star populations and movement: The concept of different populations of stars has undergone considerable change over the last several decades. Before the 1940s, astronomers were aware of differences between stars and had largely account
The Milky Way is the galaxy that contains our Solar System.[1][2][3][nb 1] This name derives from its appearance as a dim "milky" glowing band arching across the night sky, in which the naked eye cannot distinguish individual stars. The term "Milky Way" is a translation of the Clas...
The first attempt to describe the shape of the Milky Way and the position of the Sun within it was carried out by William Herschel in 1785 by carefully counting the number of stars in different regions of the visible sky. He produced a diagram of the shape of the Galaxy with the Solar ...
The formation of our Milky Way can be split up qualitatively into different phases that resulted in its structurally different stellar populations: the halo and the disk components1,2,3. Revealing a quantitative overall picture of our Galaxy’s assembly requires a large sample of stars with very...
In this picture, the galactic latitude tells you how much an object lies above or below the plane of the Galaxy, and the longitude specifies the angle away from the Galactic Centre. The above image shows a schematic diagram of what we think the Milky Way Galaxy looks like, with an indicat...
The European Space Observatory (ESO) has released an impressive 9-gigapixel image of the central part of the Milky Way Galaxy.
Galaxy: structuregalaxies: kinematics and dynamicsContext. It has recently been discovered that the Galactic bulge is X-shaped, with the two southern arms of the X both crossing the lines of sight at l=0 and |b|>4, hence producing a double red clump in the bulge color magnitude diagram....

The diagram has already helped researchers learn to distinguish white dwarfs dominated by hydrogen and white dwarfs dominated by helium. It also suggests that the stars in the disc and halo of the Milky Way are different ages, suggesting there were two galactic formation events....
