How did the Berlin Dadaists repurpose astronomical imagery for political ends?
May 1, 2026 · 9 min read · by Walensky
Berlin, 1920s. In the smoke-filled back rooms of the Café des Westens, a handful of revolutionary artists turned constellations into weapons of ideological warfare. While post-war Germany nursed its wounds, Hannah Höch, Raoul Hausmann and John Heartfield hijacked images of distant galaxies to denounce the political chaos surrounding them. Their genius? Transforming celestial majesty into biting satire, stars into propaganda bullets.
Here is what Dada's astronomical détournement brings: a masterclass in visual subversion, a reflection on the political use of cosmic symbols, and timeless inspiration for anyone seeking to give meaning to images.
Today, we admire space photographs as windows onto infinity. But how can we understand that these very same celestial images could become instruments of protest? How did these artists transform astronomy – a supposedly neutral and universal science – into an incendiary political manifesto? This story remains little known, yet it reveals a fascinating dimension of the Berlin Dada movement.
Rest assured: you need not be an art historian or an expert on Weimar politics to grasp the power of these creations. The story I am about to tell speaks of creative daring, revolutionary collages and that unique ability the Dadaists had to transform the ordinary into the extraordinary.
I promise that by the end of this reading, you will never look at astronomical images the same way again. You will understand how a simple crescent moon can become a political symbol, and why this lesson remains burningly relevant.
When stars become bullets: the explosive context of Dada Berlin
Berlin of 1918-1923 resembles an ideological battlefield. The Weimar Republic teeters, Spartacists clash with Freikorps in the streets, hyperinflation devours savings. In this maelstrom, the Berlin Dadaists – unlike their more nihilistic Zurich cousins – chose radical political engagement.
Hannah Höch, Raoul Hausmann, George Grosz and John Heartfield then invented political photomontage. Their weapon? Scissors, glue, and devastating irony. They plundered illustrated magazines, cutting out photographs of politicians, generals, film stars. And among these images emerged astronomical representations : nebulae, planets, lunar craters, constellations.
Why astronomy? Because it embodied everything they despised: the supposed order of the cosmos set against social chaos, the cold distance of science while people starved, the abstract universalism of elites while bodies littered the cobblestones. The Berlin Dadaists would therefore divert this celestial imagery to make it the exact opposite of its original function.
The cosmic collage technique: deconstructing to rebuild meaning
Hannah Höch mastered this particular alchemy. In her work Schnitt mit dem Küchenmesser Dada durch die letzte Weimarer Bierkuchbauchepoche Deutschlands (Cut with the Kitchen Knife Dada Through the Last Weimar Beer-Belly Cultural Epoch of Germany), she integrates fragments of astronomical images into an astonishing visual chaos.
Politicians' heads float through space like wayward planets. A industrial machine wheel becomes a galaxy. A crescent moon hovers above a protesting crowd. The technique is surgical: each celestial element torn from its neutral scientific context is reinjected into a new system of meaning violently political.
Raoul Hausmann went even further. His photomontages juxtapose star charts with scenes of urban violence, suggesting that the cosmic order so praised by astronomers is merely an illusion in the face of earthly disorder. Constellations become military diagrams, nebulae resemble shell explosions.
Lunar symbolism in the service of satire
The moon occupies a particular place in this subversion. The romantic symbol par excellence, it becomes for the Berlin Dadaists a mocking eye observing human stupidity. John Heartfield, master of political photomontage, regularly places ironic crescent moons above scenes showing bourgeois hypocrisy or military brutality.
This diverted use of lunar imagery transforms a universal poetic symbol into a sharp commentary on the humanist pretensions of a society tearing itself apart. The contrast is striking: the supposed serenity of celestial bodies against earthly violence.

To understand this political use of astronomy, one must grasp what this science represented in Weimar Germany. Astronomy embodied rational order, mathematical predictability, the harmony of celestial spheres – everything society claimed to be but manifestly was not.
The Berlin Dadaists exposed this hypocrisy. When Hausmann glued a nebula photograph onto a portrait of President Ebert, he suggested that discourses on cosmic order served to mask real political chaos. When Höch integrated astronomical diagrams into her fragmented compositions, she visually demonstrated that this supposed order was merely a puzzle in pieces.
This critique goes beyond simple satire. The Berlin Dadaists questioned the ideological use of science. Why did elites invest in observatories while children died of malnutrition? Why were discoveries about distant stars celebrated while bodies rotted in the still-fresh trenches?
Planets as symbols of disconnected power
Representations of planets in Dadaist photomontages function as visual metaphors for power detached from earthly realities. A perfect, distant sphere becomes the symbol of political elites orbiting in their own sphere, indifferent to the suffering below.
George Grosz used this symbolism with particular cruelty. His political leaders are often depicted as grotesque celestial bodies, bloated and distant, while the people crawl on the ground. Astronomical imagery serves here to visualize social distance, the unbearable gap between rulers and ruled.

Photomontage as a weapon of massive visual destruction
The technical revolution carried out by the Berlin Dadaists cannot be underestimated. Before them, collage existed (Picasso, Braque), but never with this explosive political charge. Photomontage became an inverted propaganda weapon: where power used images to glorify, the Dadaists used them to demolish.
Astronomical imagery played a crucial role in this strategy. Why? Because it came from serious scientific publications and respectable educational magazines. By tearing these images from their legitimate context to place them in chaotic, satirical compositions, the Dadaists desacralized authority itself.
A lunar crater becomes a blind eye. A constellation transforms into a network of barbed wire. A solar eclipse evokes a gaping hole in the social fabric. Each diversion is an act of semantic sabotage, a visual guerrilla war against established systems of meaning.
The cosmic dimension of political absurdity
By placing astronomical images into their political compositions, the Dadaists created a vertiginous contrast. Cosmic immensity highlights by comparison the ridiculous smallness of human ambitions. Generals parading before galaxies seem pathetic. Politicians haranguing beneath nebulae appear derisory.
This technique anticipated what we would today call cosmic irony. Faced with the infinity of the universe, our wars, our political systems, our ideological certainties appear for what they are: fragile and temporary constructions, often absurd.

The forgotten legacy: when stars carried revolutionary messages
This subversive use of astronomical imagery by the Berlin Dadaists has largely disappeared from historical analyses. Their political photomontages are remembered, but the specific role of cosmic references in their visual arsenal is often forgotten.
Yet this legacy deserves rediscovery. In an era when space images circulate massively on social networks, when NASA publishes spectacular photographs of distant galaxies daily, the Dadaist lesson remains relevant: no image is neutral, every representation can be diverted, resignified, politicized.
The Berlin Dadaists showed us that stars can lie, that the apparent order of the cosmos can serve to mask earthly disorder, that the beauty of nebulae can divert attention from social injustices. They taught us to question the political use of supposedly apolitical images.

What remains of this Berlin adventure in which the Dadaists transformed astronomical images into political grenades? First, an invitation to critical vigilance. Each time we admire a photograph from the Hubble telescope, we can ask ourselves: what is this image for? What does it make us forget? Which world order does it legitimize?
The Berlin Dadaists bequeathed us a method: radical diversion. Taking what is meant to inspire passive wonder and transforming it into a tool of active questioning. Seeing in each constellation not only cosmic beauty, but also the power structures that decide which beauty deserves to be celebrated.
Their subversive use of celestial imagery reminds us that the most effective political art does not always shout its slogans. Sometimes it whispers its critiques by placing a simple ironic moon above a scene of violence, transforming a nebula into a social metaphor, making planets the symbols of a disconnected power.
This story of the Berlin Dadaists and their astronomical diversion deserves to inspire our own creations. In a world saturated with spectacular images of space, perhaps we need to relearn their fundamental gesture: tearing images from their established functions to give them new meanings, more urgent, more earthly, more human.
Frequently Asked Questions
Why did the Berlin Dadaists specifically use astronomical imagery rather than other types of scientific images?
Astronomical imagery possessed several strategic qualities for the Berlin Dadaists. First, it embodied order and harmony – exactly what they wanted to denounce as illusion in Weimar society. Second, these images came from respectable sources (scientific publications, educational magazines), which amplified the subversive effect of their diversion. Finally, the contrast between cosmic immensity and the smallness of human conflicts created a powerful visual irony. Stars and planets served as a distorting mirror revealing the absurdity of political life. Unlike biological or chemical images, astronomy also evoked the universalist and timeless pretensions of elites, making it a perfect target for their political critique.
How did the Dadaists obtain astronomical photographs for their photomontages?
The Berlin Dadaists were true methodical plunderers of the visual culture of their era. They systematically cut up popular illustrated magazines such as Berliner Illustrirte Zeitung, popular science journals, encyclopedias, and even school textbooks. The interwar period saw an explosion of astronomical photography made accessible to the general public thanks to technical advances. Observatories regularly published their discoveries in the press, making these images easily available. Hannah Höch, in particular, maintained considerable personal archives of cut-out images, classified by theme. This almost archival dimension of their practice transformed their studio into a laboratory of visual resignification, where each astronomical image awaited diversion from its initial educational function toward a new political and satirical life.
Does this political use of space imagery still exist in contemporary art?
Absolutely, and the legacy of the Berlin Dadaists remains vibrant, though often overlooked. Many contemporary artists use space images from NASA or observatories to comment on our era. Think of the works of Trevor Paglen, who diverts satellite imagery, or those of Thomas Ruff, who manipulates astronomical photographs to question our relationship with scientific images. The difference? Today, cosmic imagery has become even more spectacular and omnipresent, making it an even richer material for critique. Social networks are full of photographs of galaxies used as inspirational wallpapers, exactly the kind of comforting use the Dadaists would have loved to subvert. Their fundamental lesson – that no image is neutral and that any beauty can mask power relations – remains burningly relevant in our civilization saturated with spectacular space images.
