Good question Boaz. Willy Ley wrote a science fact peice in most if not all issues of Galxy at this time, as far as I can see and they were generally pretty good; well researched.@Bick In the second post of this thread, you've posted a picture of the cover of Galaxy Science Fiction #43. It seems there is an article titled The Demotion of Pluto by Willy Ley. I am curious about the title since the actual demotion of Pluto to dwarf planet in the last fifteen years.
Edit: A quick search shows Willy Ley as a regular contributor to GSF, a writer of space exploration both factual and fictional, and a cryptozoologist. I found that the article about Pluto comes from 1956 and is related to or either retitled as a German language article Die Suche nach Planetem X in 1959.
I'm not a scientist. My poorest grades were always in physics, biology, chemistry, etc... but exploration interests me. As a child, the nine planets were drilled into my brain... and I find it interesting that there may have been doubt as to Pluto's status even before it was taught to me.
Thank you Bick, for giving me another excuse to go off-thread on behalf of Cliff Simak.Good question Boaz. Willy Ley wrote a science fact peice in most if not all issues of Galxy at this time, as far as I can see and they were generally pretty good; well researched.
In this piece he is not actually predicting the diminishment of Pluto to dwarf planet status (which happened a lot later as you rightly point out), but referring to a suggestion at the time, by Dr Gerard Kuiper of the University of Chicago, that Pluto may be a runaway moon, that escaped from the orbit of Neptune in the early solar system. He then goes on the compare the 'planetary' characteristics of Pluto with the predicted characteristics of the "Planet X", proposed to exist by Lowell, to see if how close it comes to meeting the requirements for a true planet. These include the Bode-Titius rule (worth googling) and the specific orbit. Pluto didn't quite match Lowell's expectations when it was discovered by Clyde Tildsley apparently. Quite interesting.
Got it, thanks. Incidentally I expect to be posting something about a freebie trove coming my way, sometime in the next few weeks.Can we stick to thread topic please? This thread is for posting about science fiction and fantasy magazines we own from the Golden Age or earlier. Thanks.
