Re: APOD: Perseid Meteors Over China (2013 Aug 21)
Let's see, over four hours the earth rotates by sixty degrees; therefore, each of the 68 frames that were combined was rotated as needed to compensate for earth's rotation, so that the patterns of stars from different frames overlapped correctly. That leaves a puzzle: Why is the silhouette of a tre...

Re: Radiation & Habitable-zone Planets
Given that the periodic table is universal, it doesn't seem to be accidental that life forms on earth are comprised primarily of carbon, hydrogen, oxygen and nitrogen.

If you take a close look, you'll see what appear to be H II regions throughout the galaxy that are colored green. I went to the Hubble Legacy Archive and the combined color image has the same green regions. It can't be ionized hydrogen, but what would cause the green structures? I cropped one of the...

Re: Black Hole = Big Bang = Another Universe
No. We're here because if we weren't, we wouldn't be. Nothing to do with odds. So, I take it that you're not a fan of the Drake Equation. Why do you say that? The equation seems to me perfectly valid, although perhaps not complete. But it doesn't have anything to do with the fact that the Universe ...
