The coordinate grid was laid against the sky to fix the stars and for centuries it seemed to work as planned. Recently, slowly, almost asymptotically, the grid begins to move with respect to itself — abrading, degrading — and therefore deteriorates. In fact, Declination -14 now sags along its whole length so that Declination +14 […]
Astronomy
“The universe is what it is, and we’re trying to find out what it is,” John Huchra told me. “The explorers of the new world weren’t trying to prove theories, they were looking at what was out there.” Huchra was an observational astronomer, as opposed to a theorist. Theorists say that, given physics, the universe […]
I grant this is just straight-up astroporn but let’s try to make it legit. It’s a picture taken in 2009 by the Hubble Space Telescope of NGC 3372, the great nebula in the constellation Carina, which is in the sky over the southern hemisphere. “Nebula” is an old astronomical word that has referred to a […]
In 2007, the Galaxy Zooites — 100,000 housewives, high school students, helicopter pilots, physicians, school teachers, truck drivers, secretaries, and a mobile home park manager from all over the world – got together on the internet under the guidance of some astronomers and classified galaxies. Galaxies tend to be either spirals or ellipticals, computers are […]
Sublime: you don’t hear it much except as an adjective meaning really, really good, used the way “divine” or “glorious” “wonderful” are used, just another adjective, nothing to do with divinity or glory or wonder. But really, sublime describes something that takes you beyond the ordinary — Glenn Gould plays Bach sublimely — something […]
I’m not exactly sure what this is a picture of — I’ve seen it somewhere, maybe a graphic picture of noise? some computer thing? — but given his title, Abstruse Goose clearly means us to think of it as stars. #1. It looks real. #2. Abstruse Goose, if you’re out there, can you tell us […]
This is how astronomers think giant galaxies form super-massive black holes (the adjectives are the astronomers’). Way back at the beginning, maybe a billion years after the birth of a 14 billion year old universe, enormous galaxies a hundred times bigger than the Milky Way were born, pulling themselves together out of clouds of stars […]
The Perseids are reliable, regular shooting stars, a meteor shower that shows up nights in late July every year. I didn’t see the Perseids this year myself because Baltimore’s skies are a rich carnelian haze that hold nothing much and certainly not meteorites. And Heather didn’t see them because, she thinks, of light pollution. To […]
