The Milky Way and the Galaxies
1975There are fields in observational astronomy that are less suited to scientific work by the amateur observer. The following section describes one of them, for only rarely will the amateur astronomer be able to take an active part in the attack on the unsolved problems of galactic research.

On a clear, moonless night, away from city lights, one can see a broad streak of light spanning the heavens. During the northern winter months, it stretches from south to north, eastwards of the well-known constellation Orion. In the summer months, it stretches from the Southern Cross, through the tail of Scorpius, northwards to Cygnus.

The physical conditions in the interstellar medium of the Milky Way are briefly reviewed. It is noted that the local interstellar medium shows relatively uniform abundances and dust/gas ratios; in fact recent measurements of the 12C/13C ratio indicate that the gas is homogeneous to better than 15%.

The Milky Way: An active galaxy?
AIP Conference Proceedings, 1992The behavior and interactions of one or more core black holes is described for the mass density environment of the galaxy core and comparisons made between this environment and that of a large spherical stellar system typical of an active galaxy. Data is presented for a range of galaxy types in local galaxy clusters that indicates jetting with kinetic ...

We have been treating stars as though they were isolated objects in the sky, unrelated to anything else in the universe. Actually they are members of groups that ultimately influence the history and evolution of these same stars in various ways. Every star has neighbors all around it in the sky as though it belonged to some vast ensemble of stars that ...

The Milky Way and Other Galaxies
2018In Chap. 6 we learned about the stars and that all individual stars we see are contained in our home galaxy, the Milky Way. It has been estimated that 80% of the people who live in North America cannot see the Milky Way due to light pollution. At sea the opportunity to view the Milky Way in all its glory is a real possibility, depending on the time of ...
