Topic: Harold Johnson (astronomer)


  
  Harold Lester Johnson, April 17, 1921—April 2, 1980 | By Gérard H. de Vaucouleurs | Biographical Memoirs
HAROLD JOHNSON, ONE OF the most productive and influential observational astrophysicists of this century, was born in Denver, Colorado, on April 17, 1921, the son of Averill C. and Marie (Sallach) Johnson.
Johnson developed convenient forms to facilitate (in those precomputer days) the reduction of photoelectric observations, designed an ingenious analog-to-digital device to measure the star and sky deflections on chart records of the photo-current, and defined the rigorous procedures to be followed to obtain the highest precision in this type of observation.
Johnson's years at Texas were very productive in the sense that he developed and used much new equipment at McDonald Observatory, but frustrating because he failed to receive from the university administration whole-hearted support for the kind of research and development he wanted to give to the department and, especially, the observatory.

Sir Harold Spencer Jones (March 29 1890 – November 3 1960) was a British (The people of Great Britain) astronomer (A physicist who studies astronomy).
He determined the solar parallax (The apparent displacement of an object as seen from two different points that are not on a line with the object) from observations of 433 Eros (additional info and facts about 433 Eros) during its close approach in 1930–1931.
He was awarded the Gold Medal of the Royal Astronomical Society (additional info and facts about Gold Medal of the Royal Astronomical Society) in 1943 and the Bruce Medal (additional info and facts about Bruce Medal) in 1949.

It was Harold L. Johnson – brilliant, mercurial, and outspoken – who ushered in the modern era of electronic measurements of starlight at Lowell Observatory using the 21-inch telescope.
Johnson was a pioneer in the development of the photoelectric photometer, an instrument that measures light through colored glass filters.
Johnson built several photometers while at Lowell as well as the electronic amplifiers needed to record data as a squiggly trace on a moving strip of chart paper.

Astronomically it is generally thought of in terms of measuring the colours and brightness of stars but it also includes the investigation of surface brightness in extended objects such as the moon, the planets, galaxies and, for example, arcs of emission nebulosity in our own galaxy.
Astronomers also use /absolute/ magnitudes, which is the true, intrinsic brightness of a star.
Professional astronomers make use of several tens of different filter systems, some of which have been developed for very specific purposes such as the isolation of spectral lines of a single chemical element.

In 1950 he sugested the exsistence of a sphere of incipent cometary material surrounding the solar system, which is now called the 'Oort cloud.' He proposed that comets detached themsleves from this 'Oort-cloud' and went into orbit around the sun.
Pursuing the theoretical work of several astronomers on the evolution of stars, Sandage, with Harold L. Johnson, demonstrated in the early 1950s that the observed characteristics of the light and colour of the brightest stars in various globular clusters indicate that the clusters can be arranged in order according to their age.

 Breakup may have begun above California / Caltech astronomer noted 'debris shedding' as Columbia passed overhead
Top NASA officials appealed for photographs or video evidence from amateur sky-watchers on the West Coast, after confirming they had received detailed written descriptions from a Caltech radio astronomer who said he saw what appeared to be "debris shedding from the orbiter" as it streaked over the eastern Sierra.
The image is one of five snapped in sequence at 5:53 a.m., when the shuttle's sensors began to fail.
NASA on Sunday appointed an independent team of investigators to find the cause of the Columbia disaster, and named to head it retired Adm. Harold Gehman Jr., who previously ran the government's probe of the suicide bombing in Yemen of the U.S. destroyer Cole, in which 17 Navy sailors died.

 In Memorium: Antoinette de Vaucouleurs
Antoinette also worked with her husband on the first quantitative spectral population analysis of a galaxy (the bar of the Large Magellanic Cloud) from the strength of its absorption lines.
During this work she first noticed in 1958 that the magnitudes of the central parts of several Seyfert galaxies differed perceptibly over a one-month interval — the first detection of variability in galactic nuclei — and her suspicions were verified ten years later when the variations were firmly established by others.
In her 40 years of professional activity, she was the author or co-author of more than 60 research papers and galaxy catalogues which have been extensively used by astronomers.

 The Religious Sublime
Its causes, affects, ethics and aesthetics all began to be analysed in a tradition which stretches from John Dennis's The Advancement and Reformation of Modern Poetry (1701) to the twentieth-century analyses of, among others, Harold Bloom and Jean-François Lyotard.
This trembling joy (to paraphrase Burke) surrounding the imagination may be illustrated by the figure of the astronomer in Johnson's Rasselas (1759) who offers an example of the recognition of the alarming power of the synthetic imagination, of its capacity to contribute to 'knowledge' and its ability to inflict a feeling of 'calamity'.
Yet despite this ambivalence towards the imagination which persists throughout the eighteenth century, the consequences that the sublime experience had for both aesthetics and for epistemology in the period remain considerable.
