It was 60 years ago today that the Beatles first appeared on “The Ed Sullivan Show.” This post originally ran in 2012. I was watching the Beatles on “Ed Sullivan” the other night when I got to thinking about Galileo. “Ladies and gentlemen, here are The Beatles!” cried Ed, in his imitable style, and the camera […]

This post first ran on Dec. 31, 2010, though with a different main image, and it has run just about every New Year’s Eve since then. Back in the day, the lead image was a close-up of the crown of the 2009 pole. That image still appears as part of this essay, only farther down. […]
Lately I’ve been lingering in Bortle 1 zones, rare dark places untroubled by human lights. On the scale, 1 is where your eyes discern the faintest satellites and the fuzzballs of nearby galaxies. When you wake hours before dawn, the atmosphere lacks the flashing planes, and sometimes satellites seem to have fallen asleep. The stars […]
Even at a thousand words, this picture would be way undervalued. But there it was, waiting to be taken (the picture, that is, not the object). So I took, during a visit to Florence, and I wrote, in 2014, and I redux, here, because some images you just can’t get out of your head. The […]

A version of this essay originally appeared June 15, 2012, as part of this site’s Father’s Day series. In the final paragraph I’ve updated one temporal reference (“two weeks ago yesterday” to “May 31, 2012”) and added one recent personal development. “My father,” I would say, “is older than the universe.” The line has always […]
One cold night a couple of weeks ago, my family and I bundled up to bike out to a park in one of Seattle’s northern suburbs. We have a routine for such trips after all these years. First we layer, and then we bedeck our bikes with lights: front lights, back lights, hub lights, even […]
Time again to reach into the “Ask Mr. Cosmology” mailbag and see what readers want to know about . . . The Wonders of the Universe! Q: Does the word “creation” imply a Creator? Mr. Cosmology: No, thank God. Q: What does Mr. Cosmology think of the theorists who argue for the anthropic principle? Mr. Cosmology: They’re […]
