Queer Facts about Star Gazers (Jul, 1936)

Queer Facts about Star Gazers

HAVE you ever seen a picture of a square star? Why do astronomers live longer every year than anyone else? Would you believe it is impossible to look through the world’s largest telescope? Do you know astronomers don’t always point their telescopes at the stars they really want to observe?

There are no square stars, of course, although the scientists make photographs that show them as squares. They do it with a special camera equipped with a traveling back that moves up and down so the rays from separate stars are recorded as square patches on the film. This makes it easier to measure their comparative brilliance.

Blast of Giant Atom Created Our Universe (Dec, 1932)

This is a pretty amazing article. It’s a concise summary of the big bang theory published only 3 years after Edwin Hubble made his famous observations about the redshifts of distant galaxies. Yet it’s pretty much identical to one you’d see today. Only a few details like the size of the initial “atom” and the age of the universe seem off. Keep in mind it took another 35 years or so before the scientific community came to accept that the big bang really happened.

Blast of Giant Atom Created Our Universe

By Donald H. Menzel
Harvard Observatory

OUT of a single, bursting atom came all the suns and planets of our universe!

That is the sensational theory advanced by the famous Abbe G. Lemaitre, Belgian mathematician. It has aroused the interest of astronomers throughout the world because, startling as the hypothesis is, it explains many observed and puzzling facts.

According to Lemaitre’s theory, all the matter in the universe was once packed within a single, gigantic atom, which, until ten thousand millions years ago, lay dormant. Then, like a sky-rocket touched off on the Fourth of July after having remained quietly for months on a store shelf, the atom burst, its far-flung fragments forming the stars of which our universe is built.

Flashlight, 5 Power Telescope, Drinking Cup—All in One (Oct, 1933)

Any fool could come up with a Flashlight/Telescope combo, but it takes a true creative genius to add the drinking cup.

Flashlight, 5 Power Telescope, Drinking Cup—All in One
IT’S a flashlight, but take out the batteries and it’s a telescope. The combination instrument, now on the market, has several uses for the camper. As a flashlight it has a focusing beam. The front lens can also be used as a sun glass to start fires, while the eyepiece is a good magnifying glass. Included in the tube with the batteries is a small drinking cup. By removing the batteries, bulb, and drinking cup, the camper has a fair five-power telescope. The instrument is built to provide for an adjustable telescope for varying distances.

New NASA Space Telescope (Sep, 1979)

The funny thing about this ad is that “NASA Space Telescope” was the original name of the Hubble Space Telescope and Perkin-Elmer is the contractor that delivered a flawed main mirror, requiring a very expensive and difficult repair mission.

The NASA Space Telescope: Getting ready for the clearest look yet into space

The NASA Space Telescope, scheduled for launch by the Space Shuttle in the 1980s, will orbit the earth at an altitude of 310 miles. Unlike ground-based telescopes which are restricted to a narrow spectral window and subject to distortions by the earth’s atmosphere, the Space Telescope will provide astronomers with the clearest view yet of the universe.

A Grinding Rig

WALKING around a barrel is undoubtedly a tedious procedure, but on the other hand it is the simplest method of grinding and polishing a telescope mirror. However, a number of our disciples have evidently gotten just a bit tired of this ambulatory procedure and have written to inqure whether there exists a more satisfactory and sedentary method of grinding said telescope mirrors. There is. As a matter of fact a number of such grinding rigs are described in Amateur Telescoping Making edited by Albert Ingalls.
