The Milky Way In Three Dimensions - Ministry Of Science And Higher ...
When Galileo pointed his first telescope at the Milky Way in the early 17th century, he noticed it consists of countless stars. Since that time, studying the properties and history of our Galaxy has absorbed many generations of scientists. Writing in Science, Polish astronomers from the Astronomical Observatory of the University of Warsaw present a unique three-dimensional map of the Milky Way. The map provides insights into the structure and history of our Galaxy. Aug 2, 2019 ... Presently, it is believed that the Milky Way is a typical barred spiral galaxy that consists of a bar-shaped core region surrounded by a flat ... [ReadMore..]

A Three-dimensional Map Of The Milky Way Using Classical Cepheid ...
The Milky Way is a barred spiral galaxy, with physical properties inferred from various tracers informed by the extrapolation of structures seen in other galaxies. However, the distances of these tracers are measured indirectly and are model-dependent. We constructed a map of the Milky Way in three-dimensions based on the positions and distances of thousands of classical Cepheid variable stars. This map shows the structure of our Galaxy's young stellar population, and allows us to constrain the warped shape of the Milky Way's disk. A simple model of star formation in the spiral arms reproduces the observed distribution of Cepheids. Jun 27, 2018 ...

How Big Is The Milky Way? | Plus.maths.org
A question which has been vexing astronomers for a long time is whether the forces of attraction between stars and galaxies will eventually result in the universe collapsing back into a single point, or whether it will expand forever with the distances between stars and galaxies growing ever larger. Toby O'Neil describes how the mathematical theory of dimension gives us a way of approaching the question. May 1, 2001 ... As you can see, the result is a rather convincing straight line with slope about 1.82 and we conclude that the box dimension of our photo of the ... [ReadMore..]
The Structure And Dynamics Of The Milky Way Galaxy | Britannica
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 clusters. Shapley found that, instead of a relatively small system with the Sun near its centre, as had previously been thought, the Galaxy is immense, with the Sun nearer the edge than the centre. Assuming that the globular clusters outlined the Galaxy, he determined that it has a diameter of about 100,000 light-years and that the Sun lies about 30,000 light-years from the centre. (A light-year is the Assuming that the globular clusters outlined the Galaxy, he determined that it has a diameter of about 100,000 light-years and that the Sun lies about 30,000 ... [ReadMore..]
