In a [yet-to-be-peer-reviewed new paper]() submitted to the journal *Physics Education*, a group of Scandinavian astronomers argue that festive disco balls could operate like the pinhole cameras used to [safely view solar eclipses]() so that the Sun can be observed in an "easy and fun" way. "For astronomical purposes, the optics of disco balls are similar to the optics of the better-known pinhole camera," the paper's authors wrote, explaining that disco balls are "collections of what are known as pinhead mirrors," or flat mirrors similar to those inside cameras, that are "each the reflective equivalent of a pinhole camera aperture." While pinhole cameras are often used "as an inexpensive and safe way to observe the solar eclipses or to observe sunspots," the pinhead mirrors that decorate disco balls have much less often been used in a similar manner, with the researchers only finding a few instances of experiments that used them. Although it's easy enough to create a [pinhead mirror]() either by "breaking or covering larger mirrors," disco balls offer a much safer and cheaper alternative because they're "readily available at remarkably low prices," the paper argues. "Additionally, their associations to concerts, discotheques, and parties make them interesting and unexpected objects for demonstrating physics to schoolchildren and the general public," the researchers added. ## Reflective Surfaces As photos and diagrams from the paper illustrate, placing a mirror ball inside a room with the Sun shining in through a window projects small images of it all over the walls, much the same way the lights of a club are reflected onto the walls and dancers around and below the disco ball. To test out their boldly simple theory, the researchers placed a disco ball on a column in the middle of a room where the Sun would catch it, at an undisclosed university between March and May 2023. Not only did the mirror ball successfully reflect images of the Sun all over the room, but it also was reportedly popular with university visitors. "In particular," they wrote, "children enjoyed the opportunity of spinning the ball and watching the reflected images move across the walls." With a total solar eclipse coming up in [April 2024](), the astronomers were not only motivated to find safe ways for people to view the stunning event, but also for them to view it en masse, which makes it far more accessible than pinhole cameras, which can only be used by one person at a time. "We believe that the disco ball is a versatile and engaging tool for educational purposes," the researchers wrote, "deserving wider use both for classroom demonstrations and for public events." **More on the Sun:** [*NASA's Solar Probe Survived Flying Right Through Massive Sun Explosion*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set. I'm the proud parent of an ineffable orange cat named Mee-Mow. ### Author social links [Bluesky]()
