Vincent van Gogh’s 1889 masterpiece, The Starry Night, has long been recognized for its expressive celestial swirls. However, modern astronomical analysis reveals that the composition was grounded in actual observation rather than pure imagination. Researchers found that the night sky depicted in the canvas matches the pre-dawn horizon visible over the painter's home in Saint-Rémy, France, around July 22, 1889, in both observation and shape.
The investigation, published in the journal Scientific Reports, was conducted collaboratively by the space-science company SLLAB and the School of Space Research at Kyung Hee University in South Korea. Marking the first astronomical re-examination of the painting in four decades, the study mapped the historical positions of celestial bodies against the famous artwork.
According to the research team, the specific cluster of stars rendered in the painting matches the Hyades cluster in the constellation Taurus. First author Elijah Jeong-hyun Kim explained that, from an observational astronomer's viewpoint, the rendered group of stars is indeed the Hyades. Alongside this cluster, the composition captures a waning crescent moon and Venus, all of which fell naturally within the painter’s field of view at that time.
Using the same scientific method, the research team also proposed that the stars depicted in Van Gogh’s 1888 painting Café Terrace at Night may represent the Summer Triangle. How might recognizing the observational precision behind historical art change the way we interpret classic landscape paintings?
