I like my crackpot theory that the hexagon is the cloud top manifestation of the largest ice crystal reef in the solar system.

Re: APOD: NGC 6357s Cathedral to Massive Stars (2012 Nov 18)
Hello again: We see here the most wonderful astronomy imaginable. I always wonder though, where the mass that formed that cloud came from originally. If it was an object that exploded, it must have been a kind of big bang on its own. Such an event, if near enough to the earth could possibly cause on...

Re: APOD: A Sailing Stone in Death Valley (2012 Feb 22)
Hi All: Well, I do like the windblown water or windblown ice-floating-on-water explanation too. There is more than one way to move those rocks. I had no first hand experience with wind blown water! I am sure we now have the question answered. As to erasing the clay ridges, the floating ice explanati...

Re: APOD: A Sailing Stone in Death Valley (2012 Feb 22)
Hi All: How is it that the obvious is overlooked. Death valley is a wet place some of the time. Those rocks are moved by water in sheet flow mode during flash floods. This explains the smooth curved paths. Water in sheet flow moves in long curves as for example waves traveling slowly across flat bea...

Re: APOD: Slope Streaks in Acheron Fossae on Mars (2010 Mar
It is clear to this former geologist that sliding dark colored sand is not the explanation of the streaks. The margins of the streaks show that there has been NO disturbance of the surface whatever. Surface features continue across the streaks uninterrupted by any movement of the material. These str...

Drifting Through Interstellar Dust Clouds
I once asked astronomers on Science Friday, the NPR science radio program, if the solar system were to drift into a dust cloud, would the density be great enough to cause cooling of the earth. This seems to me to offer another variable in global heating/cooling. The astronomers were quite negative o...

Re: One-Armed Galaxy (2009 June 6)
THERE ARE TWO ADDITIONAL REMARKABLE FEATURES OF THE ONE ARMED GALAXY. ONE IS THE VERY FAINT BUT LARGE HALO SURROUNDING THE LOWER AND LEFT PORTIONS OF THE GALAXY. THE LIGHT EMITTED FROM THE HALO MUST ORIGINATE FROM STARS OF SOME SORT. ARE THEY DIFFERENT IN SOME WAY FROM WHAT IS NORMAL DO THEY OFFER A...

APOD 7 May 09 The Classification of Stars
I hope to be forgiven for commenting again on the myths infesting current cosmologies. We originate from a tiny sperm, we have invented the hydrogen bomb,(the big bang) and we die. Being prisoners of our own egos we believe the universe must do the same. Well why not, we have invented our Gods in ou...

Microwave Spectra of Molecular Clouds
Thank you so much for the discussion of the microwave spectra of molecular clouds. It is through such discussions and information that the non astronomer really learns astronomy without the requirement to struggle through mathematical astrophysics, which so many of us are not trained to do. I am alw...

Re: NGC 604: Giant Stellar Nursery Xrays (2009 Feb 05)
We should be so excited and pleased that a course in Astronomy is available to all. I would like to see some real data when it can be understood by scientists other than astronomers. For example, much is done with X-ray images, a feat that I would have thought to be impossible a couple of decades ag...

Todays image of the large stalrl forming region
We see all these wonderful images and the explanations of them but very little is said about where all this mass came from. The big bang theory, which appears to me to be just another creation theory rejiggered for scientists, does not explain anything, but it gets us off the hook for a real explana...

Re: Unusual Light Pillars Over Latvia (2009 January 12)
Well, I have heard too much and am now willing to concede (especially after examining the large image) that this is an optical effect and probably is not related to crystal growth. My prediction is that as the observer approaches the light source the fanning out of the light column increases until a...

Re: Unusual Light Pillars Over Latvia (2009 January 12)
There are a number of things going on here. It appears that the light columns are terminated by an overlying cloud deck. The ice crystals presumably are being nucleated at the interface between the lower levels of the cloud deck and the colder air near the ground. The increase of crystal aspect rati...
