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
KUNMING, July 12 (Xinhua) -- The Milky Way galaxy can be larger than previously expected and have a more complex radial structure, according to scientists. The study, conducted by researchers from Yunnan University and several international institutes, was recently published in Nature Astronomy. Usi...
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

Milky Way—home to more than 100 billionstars including our sun—providing a comprehensive chart of its structure: a stellar disk comprised of four major spiralarms and a bar-shaped core region.For the first time, our whole galaxy—from edge to edge of the disk—was mapped using real, ...
Max Planck Institute of Astronomy (MPIA) recently noticed a massive filament of atomic hydrogen gas in our galaxy. This structure, named Maggie, is located about 55,000 light-years away (on the other side of the Milky Way) and is one of the longest structures ever observed in our galaxy....

The original discovery of the Milky Way’s ‘plane of satellites’ (then just five galaxies)1preceded the advent of theΛcold dark matter (ΛCDM) model, whereΛis the cosmological constant, as the paradigm for galaxy and structure formation2. A keyΛCDM prediction is that galaxies such as ...
