This paper gives a representation of the main characteristics of extragalactic nebulae and of the methods which served their exploration. In particular, the so called redshift of extragalactic nebulae is discussed in detail. Different theories which

Man has a great tendency to get lost or to hide, as the case may be, in a jungle of details and in unnecessary complications. Why do anything simply if you can do it complicated? And still, life itself presents a sufficient number of problems to keep

Several lamellar gratings of 18-in. aperture, with 300 diffraction elements per inch, have been made for determining stellar spectra with wide angle telescopes. Central orders are missing at lambda4800, and weak at adjacent wavelengths. The two, equa

The extensive investigations of extragalactic systems during recent years have brought to light the remarkable fact that there exist two well-defined types of new stars or novae which might be distinguished as common novae and super-novae. No interme

Very little progress has been made during the last decade toward a theoretical understanding of the physical properties of matter in the solid state. The reasons for this stagnation are very clearly presented in a recent paper by A. Smekal.(1) Accord

Some time ago Baade and I called attention to the existence of certain temporary and extremely luminous objects in extragalactic nebulae. [1] We suggested: 1. These temporary objects are individual stars which behave like giant analogues of common no

A. Supernovae. - Several years ago, Baade and I made the following suggestions [1]: (1) A class of very rare temporary stars exists, some of whose major physical properties are similar to those of common novae, but in a superlative degree. We propose

As astronomy pushed its limits from the solar system to the stars of the Milky Way and to the distant galaxies and clusters of galaxies, the following three problems suggested themselves automatically. Is there matter spread throughout interplanetary

A general classification of novae in terms of integral parameters is proposed. It is shown in particular that the distribution of novae in dependence on the intrinsic luminosity at maximum brightness reveals the existence of two distinct classes, des
