You get this, right? that light travels at a certain fixed rate so TV programs (yup, light) leaving Earth in, say, 2010 would have gotten 4 light-years away and any star 4 light-years away would just be getting the program now. I’ve understood this idea for decades and I still get confused by it. __________ […]

Kepler strikes again! A couple of weeks ago, in a two–part essay, I wrote about a 1608 book by the German astronomer Johannes Kepler that scholars consider the first work of science fiction: Somnium—Latin for The Dream. This past week, I got to thinking about Kepler’s book again, after the discovery of dwarf planet 2012 VP113 (which the discoverers have nicknamed […]
(Part 2 of 2; Part 1 appeared yesterday.) Harry’s utterance “Damn damn Kepler on the Moon damn damn” immediately entered the lexicon of our little messenger world. I then introduced it to my non-work friends, who likewise adopted it as an absurdist catch-all. For years afterward my only knowledge of Kepler was as a punch […]
My first job, post-paper route, was as a messenger in the advertising department of the Chicago Tribune. As a 15-year-old aspiring journalist (and, yes, underage hire), I thought the experience might be a career path to Woodward and Bernstein heights. By coincidence, the day I started—May 1, 1974—was Watergate Wednesday, the same day that the Tribune was […]
Halton Arp — “Chip” to his friends — died in Munich on December 28, 2013, and with him a cosmological banner has fallen to the ground. It’s a banner that younger astronomers may choose to take up. If they do, however, they should be cautious: it could mean the end of their careers. As a […]
AG’s mouseover says that astronomers began charting the motions of the planets, continued through the law of gravitation, and ended up with us on the moon; so sure, the planets affect our lives. I have nothing to add. If I did, I’d probably end up telling you I read my horoscope every day. And that, […]
I received an email the other day from Nicholas Suntzeff, the director of the Astronomy Program at Texas A&M as well as a friend. (Readers might remember that he has published two guest posts with LWON.) His email was in fact a series of emails that he thought I might enjoy. It started with a […]
The news this past week that the IceCube Neutrino Observatory has fulfilled its mission by detecting neutrinos originating beyond the solar system reminds me of a story I once heard. I can’t reveal the source, though not out of a sense of journalistic responsibility. If anything, my discretion is due to journalistic irresponsibility: I don’t remember […]
