A crowd of people, many of whom are wearing protective eyewear, are looking up at the sky.

On April 8, a total solar eclipse will pass over the United States, prompting teams of physicists and astronomers to take the spotlight normally reserved for star quarterbacks in college stadiums around the country. Concession stands will serve Moon Pies, Sun Chips, Milky Ways, Mars Bars, Sunkist lemonade, Starry soda, and Eclipse and Orbit chewing gum.

Sound systems will blare Bill Withers’ “Ain’t No Sunshine,” the Beatles’ “Here Comes the Sun,” and the Rolling Stones’ “Paint It Black.” Students, faculty and staff will distribute protective eyewear, oversee public access to astronomical equipment and facilitate citizen science projects. Security—enhanced for the day—will direct traffic, monitor walk-through metal detectors and screen bags for weapons.

“We approached it as a major football game,” Michael Johnson, chief marketing and communications officer at Texas A&M University–Commerce, said of this astronomical event for which the university did not otherwise have a playbook.

The mood on campuses around the country should be festive, if eerie. Birds may stop singing. Spiders may dismantle their webs, and nocturnal bats may emerge from daytime roosts. In the United States, the moon will first block the sun in Texas before doing the same in Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine. That puts an estimated hundreds of higher ed institutions along the path of totality.

Many colleges will serve as ground zero for public eclipse watch parties in their regions, with most eyes on physicists—and, briefly, the sky. Higher ed institutions have spent years planning for April 8, including by optimizing strategies for safety and access. The programming aspires to instill awe, enhance public science literacy and foster community both on and off campus.

But a lot could go wrong. Crowds could overwhelm some campuses. Medical supplies, fuel, food and water could run short. Also, the potential for less-than-ideal weather has many holding their collective breath.

“My biggest worry is clouds,” said Aileen O’Donoghue, the Henry Priest Professor of Physics at St. Lawrence University, in northern New York. “I really, really, really, really, really want to see the corona,” referring to the hot, ionized gas or “ring of fire” that is expected to surround the moon during totality.

O’Donoghue had tried to see a total solar eclipse in Kansas in 2017, but clouds got in the way. Should the same happen this year, she has contingency plans. Australia will experience total eclipses in 2028, 2030, 2037 and 2038; she’ll go to as many as necessary in the hope of viewing at least one totality.

“Ninety-nine percent of totality is as different from totality as day is from night,” O’Donoghue said, echoing a sentiment expressed by many other physicists with whom Inside Higher Ed spoke. “At 99.9 percent of totality, it’s still daytime. You don’t get night until the entire sun is covered.”

Indeed, physicists speak of totality much in the way football fans speak of winning Super Bowls. Only totality reveals visible stars and planets. Only totality produces Baily’s beads (a “necklace” of light “beads” around the moon from sunlight interacting with the moon’s uneven surface) and shadow bands (wavy stripes of light and dark on solid-colored surfaces), according to LiveScience. Also, only those in the path of totality will see the rarely seen sun’s corona.

But for this rare celestial event, colleges have also adopted a robust, American-style consumerism. They will distribute and sell heaps of “must-have” college-branded eclipse merchandise. This includes T-shirts (some glow in the dark), stickers, keepsake guidebooks, picnic blankets, buttons, cups, photo-booth style pictures of friends superimposed with an eclipse image, and party kits that include “eclipse glasses, sunscreen, a reusable water bottle, educational materials, and lots of fun swag,” in a university-branded tote bag.

Though the natural phenomenon transcends institutional and political boundaries, some colleges have claimed pieces of it as their own. St. Lawrence University, for example, has dubbed itself the “Gateway to the Path of Totality.” (Those who agree may commemorate the sentiment with a hoodie.) Oberlin College has rebranded the celestial event “Oclipse,” which includes a logo inspired by their library’s moon-like “womb chairs.” Dallas College has labeled the phenomenon the “Big D Eclipse.” The University of Texas invites visitors to experience the “UTotal” phenomenon “the Longhorn way!

Next week will also bring a wave of solar eclipse closures at colleges around the country. At the same time, remote learning options mean that students and instructors who elect to view the eclipse may be held accountable for learning that otherwise might have occurred. The University at Buffalo, for example, has canceled in-person classes on April 8, citing an expected “more than one million visitors to the Buffalo region.” But the institution has encouraged instructors to offer remote instruction with asynchronous options for students who cannot attend in real time. (Inside Higher Ed anticipates a smattering of opinion pieces in defense of “total eclipse days,” analogous to “Let Snow Days Be Snow Days.”)

Some colleges have opted to cancel class for a few hours on the day of the eclipse. Gannon University, for example, will close from 1:20 p.m. to 4:30 p.m., and the University of Dayton will cancel class from 1:25 p.m. to 4:50 p.m.

Other university class cancellations are generous. Indiana University, for example, has canceled classes on all campuses throughout the state for the entire day—with no mention of make-up work—to “ensure that as many of our IU community members as possible can experience the eclipse.”

Those at colleges whose colors are red or green may witness an enhanced Purkinje effect in which, minutes before the totality, color saturation may appear off. Reds will darken, and greens will brighten in “otherworldly” ways. Wildlife reactions, changing winds, and scrambled radio waves may also be more pronounced during totality. But community members at Duke University, whose main color is a shade of navy blue, may hesitate to wear the red of their rivals at North Carolina State University (especially after Sunday’s NCAA tournament game).

For many physicists, the eclipse also presents a welcome opportunity to depoliticize science.

“I was not happy with a lot of the way science was presented during the pandemic. People tried to use it to push agendas,” said David Donovan, professor of physics and department head of physics at Northern Michigan University. With the eclipse, “you see something neat, and it doesn’t matter what your politics are.”

In anticipation of April’s total solar eclipse, Inside Higher Ed offers a Harper’s Index-like statistical poem for physics and astronomy teachers and students around the country. Many have spent years preparing for this minutes-long, community-minded event that, in large part, relies on clear skies.
