Love your universe. Here’s how.

First, as we discussed, there is forest bathing (note the comment on the June 15 post about regular forest-bathing excursions in Lowell, Mass.). Now we turn to star gazing. For both, you need to leave behind superfluous stuff like social media and bright lights.

Margaret Regan writes for the Guardian, “Take a nighttime drive into Arizona Sky Village, in a remote valley in south-east Arizona, and the only thing you can see clearly are the millions of stars twinkling overhead. Beyond the light show, the sky is a deep inky black, and the ground below is nothing but shadows. Dimmed car headlights might pick up spooked jackrabbits hopping through the desert brush, but the village’s unlit houses are all but invisible in the darkness.

“That’s the way the residents of this astronomy-loving community like it. The less light, the better their view of the universe.  …

“Arizona Sky Village is home to a quirky community of stargazers. Shielded by the nearby Chiricahua mountains from urban sky glow – scientists’ poetic name for light pollution – nearly every house in the rural 450-acre development has its own domed observatory, complete with an array of telescopes.

“Outdoor lights are strictly forbidden; blackout shades are required in every window of every house; and nighttime driving is discouraged. Most residents don’t want to be bothered with driving at night anyway: they’re too busy scanning the skies.

“ ‘This is what we do,’ villager Frank Gilliland says cheerfully one starry night as he peers through the community’s biggest telescope, a 24-incher belonging to neighbor Rick Beno. At the moment, the scope is aimed at the Milky Way through an open hatch in the dome of Beno’s personal observatory, giving Gilliland a crystal-clear view of the Orion nebula, a remarkable 1,344 light years away. …

“Most of the Sky Villagers had technical or scientific careers – Dr Fred Espenak, a bona fide astronomy pro, is a retired Nasa astrophysicist known as Mr Eclipse – but [Arizona Sky Village founder Jack] Newton spent his working life managing department stores in his native Canada. He always made time for the sky though, rambling miles into the countryside outside his hometown of Victoria. …

“When Jack retired, the Newtons wanted a break from rainy Victoria and its murky skies. After a first retirement stop at a sky village in Florida, Newton and development partner Gene Turner came out to Arizona to scout dark places.

“The isolated stretch of treeless desert they found outside Portal was perfect: it was sparsely populated, 150 miles distant from Tucson, the nearest city, and velvety black at night. Now some 21 households live there peaceably under Newton’s Law: they cover up their windows and they turn off the ‘goddam’ lights. …

“Even Arizona’s state government – not known for progressive policies – has restricted electronic billboards. The flashy placards are allowed only in several designated sites at least 75 miles from the venerated Grand Canyon and from the Kitt Peak and Mt Lemmon observatories. In 2012, the then governor Jan Brewer vetoed a 2012 attempt to light up more of the state’s highways with dancing electronic videos, declaring that she refused to put astronomy in jeopardy. As she noted, the industry contributes $250m annually to Arizona’s economy and employs more than 3,300 people.” More here.

Seems a shame to have to make economic arguments to do good, but whatever works. We do need to keep seeking common ground when addressing challenges.

Every once in a while reporter Ted Nesi adds a tidbit to his valuable “Saturday Morning Post” that doesn’t seem to fit with the news from Rhode Island and yet fits everywhere. This link from the Virginia Quarterly Review (VQR), a “national journal of literature and discussion,” is one such example.

Amanda Petrusich writes in part, “Darkness is a complicated thing to quantify, defined as it is by deficiency. … Unihedron’s Sky Quality Meter is the most popular instrument for this kind of measurement, in part because of its portability (about the size of a garage-door opener) and also because it connects to an online global database of user-submitted data.

“According to that database, Cherry Springs State Park — an eighty-two-acre park in a remote swath of rural, north-central Pennsylvania, built by the Civilian Conversation Corps during the Great Depression—presently has the second darkest score listed …

“The International Dark-Sky Association (IDA), a nonprofit organization that recognizes, supports, and protects dark-sky preserves around the world, designated it a Gold-tier International Dark Sky Park in 2008, only the second in the United States at the time, following Natural Bridges National Monument in San Juan County, Utah.

“Earlier this year, I drove the six hours to Cherry Springs from New York City to meet Chip Harrison, the park’s manager, his wife, Maxine, and a park volunteer named Pam for a 4:30 p.m. dinner of baked fish. Afterward, Chip had promised, we’d go see stars.  …

“On a clear night, from the proper vantage, watching constellations emerge over Cherry Springs is like watching a freshly exposed photograph sink into a bath of developer, slowly becoming known to the eye: a single crumb of light, then another, until the entire tableau is realized. Pam pointed the telescope toward Jupiter, which had risen over the east end of the field. The four Gallilean moons—Io, Europa, Ganymede, and Callisto—were clearly visible through the lens. …

“When I got back to New York, I visited with Matt Stanley, a beloved colleague at the university where I teach. Stanley … has a particular interest in how science has changed from a theistic practice to a naturalistic one. He leads a seminar called ‘Achilles’ Shield: Mapping the Ancient Cosmos,’ and another called ‘Understanding the Universe.’

“ ‘I’ve found that probably 95 percent of my students come from either an urban or suburban environment, which means they can only see a dozen stars at night, and no planets,’ Stanley said. ‘When you say the Milky Way to them, they imagine a spiral galaxy, which is fine, but that’s not what the Milky Way looks like — it’s a big, whitish smear across the sky. I have to do a lot of work to orient them to what human beings actually saw when they looked at the sky. They don’t know that stars rise and set. Their minds explode.’ ” More here.

In Rhode Island, New Shoreham offers a pretty good look at the night sky. There are shooting stars in August. I feel lucky about that and hope that the five nearby offshore wind turbines don’t change anything.
