<<Colin Stanley Gum (1924-1960) was an Australian astronomer who catalogued emission nebulae in the southern sky at the Mount Stromlo Observatory using wide field photography. Gum published his findings in 1955 in a study entitled A study of diffuse southern H-alpha nebulae which presented a
catalog of 85 nebulae or nebular complexes.
Gum 12,
a huge area of nebulosity in the direction of the constellations Puppis and Vela, was later named the Gum Nebula in his honor. Gum was part of the team, whose number included Frank John Kerr and Gart Westerhout, that determined the precise position of the neutral hydrogen plane in space.
Gum died at age 36 (April 29, 1960) in a skiing accident in Zermatt, Switzerland.
The crater Gum on the Moon is named after him.>>

<<Colin Gum at Australia's Mount Stromlo Commonwealth Observatory near Canberra took over an existing nebula photography project begun by Clabon "Cla" Walter Allen. C.W. Allen's involvement was a bit unusual. Mount Stromlo originated as a solar observatory, and Allen was known as a solar astronomer. Initially Gum and Allen were monitoring radio noise from the sun and then (for comparison) other galactic locations. Gum noted in his final survey:
- At the Commonwealth Observatory a survey for Hα emission nebulosities in the Southern Milky Way was begun by Dr. C.W. Allen in 1950, and continued and extended by the author since late in 1951. The original aim of the project was to obtain material for the discussion on the origin of galactic radio-noise considered as at least partly due to free-free transitions in the interstellar gas.
Allen left Australia in 1951 to become the director of the University of London Observatory. Ben Gascoigne became Gum's PhD supervisor. Gum decided to write his thesis on the HII regions and continued to photograph them using a 100 mm (4 inch) Schmidt camera. Gascoigne later recounted:
- Well, after he had written his thesis he had to go into hospital for medical treatment. During the year he was away, I had to supply all the references, and found that looking them up was a tedious and difficult job – I finished up knowing an awful lot about H-alpha regions myself!.
Gum thanked Gascoigne in his survey paper for "assistance in the preparation of the manuscript for this paper, the publication of which has been delayed owing to unforseen circumstances". Gascoigne provided more than help with the manuscript, however:
- When Colin put his thesis in, the two examiners were Woolley [the Stromlo director] and a Professor Plaskett at Oxford. Woolley came in one day and said, 'Gum has failed his PhD.' I think Plaskett was the snag, because he couldn't have known anything about the subject, but I don't think Woolley read the thesis properly, anyway. I don't want to sound too critical of Woolley, because he did a great deal for the Observatory, but he did have these idiosyncrasies. I was most indignant and very distressed that Colin had failed, because I thought he was really good ... I marched in and battled away as best I could until we were interrupted – I was truly thankful for that and went home, the matter quite unresolved. Next day I was back again, batting away, and I thought I made a bit of progress. And on the third day Woolley agreed to appoint a third examiner, Cla Allen, who was by that time in London. And so Colin got his PhD.
The contrast between Sharpless coolly examining plates taken by others at the great Palomar observatory and Gum struggling to have his own 4 inch camera images taken seriously could not be more extreme!>>
