It’s stippled with gold marks, some as lines, some as arrows, some as dots. Her art is formed by ink on paper—but it’s rooted in century-old artifacts, inspired by unsung astronomy pioneers, and animated by a quest to understand light. ••• At the Harvard College Observatory in Cambridge, Massachusetts, three floors of metal cabinets house more than 550,000 glass plates, most of them eight by 10 inches, a photographic negative format dating from the mid-19th century. These plates recorded astronomical data from telescopes trained on celestial regions and objects. One side bears the print of light from distant stars; the other side had been marked with equations, arrows, circles, letters, and other nota- tions by women who were hired to interpret the data.

They counted and cataloged galaxies. With such discoveries, these women laid the foundation for modern astrophysics. They left marks of many kinds: on some of the plates, only a few arrows or characters; on others, notes from conversations between women across decades, each striving to better understand the universe. T H E N T H E M A R K S W E R E R E M OV E D from roughly 470,000 plates. So that the world’s researchers could access the plates’ historic trove of astronomical data, the col- lection needed to be digitized. In the early 2000s, Harvard astrophysicist Jonathan Grindlay began a project that’s now nearly complete: Digital Access to a Sky Century @ Harvard, or DASCH, an archive of digital scans from the bulk of the collection. According to Grindlay, getting the clearest image of a glass plate’s astronomical data requires eliminating all marks on the other side of the plate before scan- ning. This is the process: Each plate is placed on a table with its nonastronomical-data side—that is, the area where the women computers had written their observations, measurements, and notes—facing up. After an overhead camera photographs that side, the plate is moved to an area where all marks are erased by scrubbing with an ethanol-water mixture and, if necessary, scraping with a razor blade. By the time Blumenfeld heard about this process in 2019, more than 400,000 plates had been scanned. “When I learned that they were actually wiping the plates clean of the marks, I was deeply saddened,” she tells me. She set out to preserve the beauty and meaning of the marks, if only on a handful of plates. In honor of the women whose work inspired her own, Blumenfeld calls her art “Tracing Luminaries.” B L U M E N F E L D ’ S FAT H E R S AY S the first word she spoke—standing in her crib, pointing at the fixture overhead—was “light.” Her fascination with light “was there somehow from the beginning,” she says.

When a wayward chunk of space junk slammed into the moon’s back side on March 4, it was blown to smithereens while adding a fresh crater to an already considerable collection. We know that much because space-watchers could track the errant rocket booster with enough precision to predict its final resting place: Hertzsprung crater. But precisely where the space trash crashed in that 354-mile-wide pockmark wasn’t immediately clear. Of the few spacecraft circling the moon, one well suited to search—NASA’s Lunar Reconnaissance Orbiter—could take up to 12 months to find a new gouge estimated to be between 16 and 98 feet wide. As lunar exploration revs up, experts see a need for better tracking of objects in deep space and regulations for disposing of used rocket parts. “At some point in the future, an event like this isn’t just going to be a curious thing to observe,” says space archaeologist Alice Gorman of Australia’s Flinders University. “It’s going to be something which people in lunar orbit or on the surface of the moon are going to be really worried about.” — N A D I A D RA K E CHRISTINE FELLENZ, NGM STAFF.

Many of the grand sandstone cliffs that tower in and around the AlUla Valley display depictions of human figures or animals known as petroglyphs, a term derived from the Greek words petra, meaning “rock”, and glypho, meaning “to carve”. Ancient artists would use stones or tools to scrape images onto the surface of cliffs and freestanding rocks—or, in some instances, they would carve figures or lines of text in relief, standing proud of the rock surface.

I had already posed the question a half BECAME THE STUFF OF LEGEND dozen times on our journey to find remnants of the summers she spent in New York’s Catskill Mountains IN MANY JEWISH FAMILIES. in the 1950s.

She shrugs. “Maybe if there was PHOTO: ERIC BARD, CORBIS VIA GETTY IMAGES a man speaking Yiddish behind the counter.” The Catskills region sprawls across four coun- ties north of New York City, dotted with lakes and crowned with around a hundred mountain peaks. Once it was the sparkling center of Jewish summers, replete with glamorous hotels and thriving small towns. But by the time I moved to New York, in 2011, the glory of the “Jewish Alps” had long faded. Then, a few years ago, my Instagram feed started filling with pictures of bonfires and Scandinavian-style lodges in the Catskills. Was this the revival of those mythical 1950s summers? I dragged my mom, Debi, with me to find out. In the early 1900s, when Jews and other minorities were banned from upscale hotels and beaches around New York City, the Catskills offered refuge. Every sum- mer, families fled their cramped apartments for the mountains. After World War II, my grandparents— refugees from Poland—moved to the Bronx, started a family, and settled into this new tradition. When school let out, they would pack a car with bedding, kitchenware, and clothes and move to the Catskills until Labor Day. Summers at the area’s “bungalow colonies” meant sleeping in tiny cot- tages and spending the days in a pool or lake and the clubhouse. My grandfather, who ran a hosiery store in the Bronx, would visit on the weekends. My mom remembers tadpoles swimming in the creek, costume parties, and women tanning by the pool with metallic reflectors. Meanwhile, at the Catskills’ large hotels, entertain- ment was paramount. At night, comedians would do their shtick for a well-dressed audience. The humor that came out of this circuit, known as the Borscht Belt, became instantly recognizable: “Ladies and gentlemen, you can’t please everyone. Take my girl- friend: I think she’s the most remarkable woman in the world. That’s me, but to my wife…” Attendance dwindled as foreign travel became easier and hotel bans on Jews disappeared in the sixties. In the era of hippies and rock-and-roll, kitschy summers in the Catskills lost their allure. But in recent years, boarded-up storefronts have been dusted off as ice-cream parlors and taco shops. Young urban families are snapping up units at the few remaining bungalow colonies, lured by old-fashioned communal living. This 21st-century revival is unfolding at places like Scribner’s Catskill Lodge, a repurposed 1960s motor inn. Since it opened in 2016, Scribner’s has come to epitomize the Catskills of the Insta- gram era, with its barrel sauna, color-coordinated A U G U S T 2 0 2 2 29
