Scientists in South Korea calculate that the night sky depicted in Vincent van Gogh’s 1889 masterpiece The Starry Night
mirrors a precise celestial arrangement visible in the early hours of July 22, 1889, near Saint-Rémy-de-Provence.
Vincent van Gogh painted The Starry Night
in 1889. For more than a century, historians viewed it as a product of imagination and memory.
The work drew on memories of scenes he saw outside the barred window of his asylum bedroom in France. New research upends that long-held assumption, suggesting the Dutch post-impressionist painter rooted his iconic canvas in actual observation.
A team of scientists from the South Korean space science company SLLAB and Kyung Hee University in Seoul published their findings in the journal Scientific Reports. By analyzing a separate sketch considered to show the landscape of The Starry Night
, the researchers pinpointed a specific hilly vantage point.

This spot lies southwest of the asylum where the artist created the oil on canvas during a 12-month stay in southern France.
Mathematical Shape Analysis Matches the Hyades Star Cluster
The researchers simulated the night sky above the Saint-Rémy-de-Provence site. Their model revealed that in the early pre-dawn hours of July 22, 1889, the Hyades star cluster in the constellation Taurus rose alongside Venus, while a luminous crescent moon hung in a specific orientation.
Five bright stars of this constellation are visible to the naked eye without a telescope. The Hyades cluster forms a bright V
shape.
On the canvas, the Moon appears in the upper right corner diagonally above Venus in the mid-left area. Other stars are positioned to the left of the Moon.
Artists do not paint celestial bodies to exact optical scale or orientation. The team needed a specialized method to compare the canvas with the cosmos.
They employed a statistical technique known as Procrustes shape analysis. This method eliminates differences in position, size, and rotation to compare only the shape of two point sets.

The analysis revealed a tight match between five prominent stars in the central arrangement of The Starry Night
and the real Hyades cluster formation on that July morning.
That match demonstrates the work did not invent a nonexistent sky. It transferred a real observed arrangement through the artist’s personal style.
The same mathematical tool also allowed the team to map van Gogh’s 1888 painting Café Terrace at Night
onto the Summer Triangle star pattern.
Dating the Canvas Against Historical Letters and Weather Records
Late July aligned much more closely with the visual evidence.

The Moon displayed a shape closer to the painting, and the Hyades rose in the east alongside Venus. Kim noted that finding more historical French weather records and letters sent from van Gogh to other painters that mention the painting could determine its creation date even more precisely.
Expert Caution on Artistic License and Fluid Dynamics
Independent experts urge caution when attempting to anchor impressionistic art to precise astronomical dates.
Huang noted that artistic style, emotional expression, and aesthetic intent often diverge markedly from exact physical reality. Independent specialists also pointed out that astronomical alignments on a canvas must be interpreted with caution because the artist was painting rather than photographing the sky.
