Fessenkov & Rozhovsky - Pair of Gasous Dust Nebulae Photographs

拍品描述

Included in this lot: Gasous Dust Nebulae Photograph [Spiral extragalactic nebula M 31 in the constellation Andromeda with two elliptical satellites] Gasous Dust Nebulae Photograph [The spiral extragalactic nebula M 31 in red light (Isopan ISS plates plus red filter #1] Description of the work: This scarce original photograph is from an album entitled Atlas gazovo-pylevykh tumannostei [Atlas of Gaseous Dust Nebulae]. The collection was created by Vasiliy Grigorevich Fessenkov & Dmitry Alexandrovich Rozhkovsky. It was published in 1953 in Almaty, Astrophysical Institute, Academic of Sciences of the Kazakh, SSR (Kazakhstan, USSR). This is a truly impressive mounted photograph from 1953 with accompanying text page. The text and photos were compiled by Vasiliy Grigorevich Fessenkov & Dmitry Alexandrovich Rozhkovsky. The pair pioneered the studying of gaseous nebulae. Fessenkov & Rozhkovsky were leading Soviet astrophysicists. They began their study of gas-dust galactic nebulae in 1950 and created these photographs. They began the study in order to understand "evolution of structure of nebulae, turbulent phenomena in interstellar clouds and in the vicinity of hot stars." The high-quality photographs illustrated the fine structure of objects formed by the radiation of ionised gas and made it possible to reveal dust scattering the light of stars. Their work was important and the field and inspired further interest in nebulae study. Rozhkovsky discovered 30 new diffuse nebulae. Paper Size: ~ 9 1/4" by 11 1/2" Paper Type or Special Features: Mounted Photograph
