In the summer, when we are staying in New Shoreham, we can see the stars at night, including the Perseid meteor showers. But the rest of the year, newspaper alerts about cool things happening in the night sky are wasted on us. I would love to see, at least for a little while, what the residents of the Isle of Rum can see.

Kat Hill writes at the New York Times, “Rum, a diamond-shaped island off the western coast of Scotland, is home to 40 people. Most of the island — 40 square miles of mountains, peatland and heath — is a national nature reserve, with residents mainly nestled around Kinloch Bay to the east. What the Isle of Rum lacks is artificial illumination. There are no streetlights, light-flooded sports fields, neon signs, industrial sites or anything else casting a glow against the night sky.

“On a cold January day, the sun sets early and rises late, yielding to a blackness that envelopes the island, a blackness so deep that the light of stars manifests suddenly at dusk and the glow of the moon is bright enough to navigate by.

‘For this reason, Rum was recently named Europe’s newest dark-sky sanctuary, a status that DarkSky International, a nonprofit organization focused on reducing light pollution, has granted to only 22 other places in the world. With the ever-increasing use of artificial lighting at night, places where people can gaze at the deep, ancient light of the universe are increasingly rare.

“Rum’s designation is the result of a long, meticulous bid by the Isle of Rum Community Trust. The effort was led by Alex Mumford, the island’s former tourism manager, and Lesley Watt, Rum’s reserve officer, with the support of Steven Gray and James Green, two astronomers who started Cosmos Planetarium, a mobile theater offering immersive virtual tours of the night sky. Rum ‘stands for something greater,’ Mr. Mumford said, and aspires to be ‘a haven for others to experience the darkness and the Milky Way.’

“A seven-mile walk from Kinloch through the wild and empty heart of the island leads to a Greek-style mausoleum, built in the 19th century, above Harris Bay on the west side of Rum. Locals regard it as the best spot on the island to take in the night sky; on a cloudy night with no moon, one resident said, ‘you can’t even see your hand in front of your face.’ But this night was clear, and stars and meteors wheeled spectacularly overhead as the Milky Way drew a glistening smudge above the brooding mountains, Askival and Hallival. Venus, Saturn and Jupiter stood in a line above the mausoleum’s sandstone pillars.

“Plans are in motion to renovate an abandoned lodge nearby into a place where tourists could stay in their quest for celestial splendor. ‘What you are seeing is not just a 2-D map, but the four dimensions of space and time,’ Dr. Green said. ‘You are looking back into the past.’ …

“On Rum, human life is lived in the small pools of light that spill from windows or glow from headlamps. One key to attaining dark-sky sanctuary status has been to help residents adapt to and embrace the darkness. Porch lights are recessed into doorways and point down; the pier has LED lights, also pointing downward, that provide just enough illumination for marine safety; a shop’s outdoor motion-sensor lights come on only for a few minutes when needed. When the community trust started its sanctuary application in 2022, roughly 15 percent of homes and shops followed the lighting recommendations outlined by the initiative; compliance is now at 95 percent.

“The blackness of night provides more than a cosmic spectacle for humans to enjoy; it is also essential for the environment. ‘Low light levels are important for nocturnal species,’ Ms. Watt said. ‘And artificial lighting can influence the feeding, breeding and migration behavior of many wild animals.’ …

“Education — of adults and children, locals and tourists — is central to dark-sky awareness. Andy McCallum, a teacher on Rum, showed off the models and maps of stars and planets that his handful of students had designed.

“ ‘For our pupils, it’s a powerful reminder that although we live on a small island, we’re part of a vast and interconnected universe,’ he said. It made them proud, he added, to help preserve a unique environment for future generations.”

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.
