Re: Sweet influences of Pleiades (APOD 2009 April 30)
Don't worship the stars. Worship the one who made the stars and put them in their place. Great reference. Amos 5:8 Seek him that maketh the seven stars and Orion, and turneth the shadow of death into the morning, and maketh the day dark with night: that calleth for the waters of the sea, and poureth...

Re: Spiral Structure 101: (APOD 2009 April 14)
I like the density wave example of the cars in a traffic jam. The cars from behind slow down because of the traffic, and the cars in front speed up to escape the jam. If this is the case, and these density wave spirals occur in galaxies because of the elliptical orbit of the stars around the center ...

Re: ISS Expands (2009 April 6)
There's no rule that says that the space station would have to be a perfect circle; as long as it was in perfect balance, it could turn and create gravity. A hexagon or octagon shape or similar structure would work. A hub with spokes and equal weight compartments on opposite ends would work. That w...

Re: Why does Mercury have so many rayed craters? (2008 Nov 0
You can stick with Mercury being a gas giant - I will vote against it. I think the orbits of the first four planets seem too close together to form gas giants. The gas giants in our solar system have swept away a huge portion of objects in their orbits - the next planet is no closer than 4AU any of ...

Private (not public) colleges can have breaks whenever they want, but publicly funded colleges tend to take all Thanksgiving week off. Michigan is a pub...

Re: Squirreling away nuts: Strange Aurora (Saturn 2008 11 19
I guess it is pretty standard that if you see the term: infrared or microwave or xray, then you know it is a false color image. But that is generally only noticed by audiences that are trained to see that sort of thing. To the random wanderer on the internet - The connected is not always made. It mi...

Re: Squirreling away nuts: Strange Aurora (Saturn 2008 11 19
So let me make a prediction for Saturn: The hexagon shape leads to a small amplitude of the waves = fast speed of rotation. The rotational time I know is 10 hours: pretty fast! Especially considering the circumference of Saturn is 10 times our circumference. The earth had 5-6 peaks, and saturn curre...

Re: Squirreling away nuts: Strange Aurora (Saturn 2008 11 19
I knew there was a good reason for the hexagon shape! It does correspond so well to our jet stream and other streams on the spinning earth.
So what variables affect its periodic pattern? Temperature? Planet rotation speed? Day length (summer or winter)?

Re: Black Hole Binary Systems (APOD 09 Nov 2008)
I don't think they're perfect vacuums. Even if they are better vacuums than most places on earth . . . If there is gas, it is no longer a perfect vacuum. Thus it will have a possibility to transmit energy by particle collisions : sound

Even if I do think this particular picture is justified, I won't say for 100% that all of the pictures that have ever been posted were astronomy related. But lets just enjoy them. Since you mentioned Epod, I tried to take a look, but it seems to be offline for the moment. And Egghead is just funny. ...

Astronomy has nothing to do with the Earth. The earth is not a planet. It does not rotate, and even if it did, the rotation would have nothing to do with egg-balancing or even the movement of the stars over the course of the night. ---- OR ----- The rotation of the Earth plays a major role in our un...

I was just wondering that same question, bystander. It had been four. Then it was two. Now its up to four again? Its evidently highly speculative. Maybe the ones on the far side are joined together into one massive arm, and the ones on this side are one massive arm. Then there are sub-arms. I'm will...
