The Real Sky Behind ‘The Starry Night’: Astronomers Say Van Gogh Painted a July Dawn

Darlings, the most famous night sky in art may have been a morning. In a study published Oct. 22 in Scientific Reports, a team led by astronomer Elijah Jeong-hyun Kim of Kyung Hee University argues that Vincent van Gogh’s The Starry Night records a real sky: the view before dawn around July 22, 1889, with a waning crescent Moon, the planet Venus and the Hyades star cluster in Taurus. The painting hangs at the Museum of Modern Art in New York, which means a Manhattan Sunday just acquired a new reason to stand in front of it.

What the astronomers actually did

They treated the canvas like a star chart. The researchers matched the painting’s bright points to the computed positions of real objects, using a shape-matching method called Procrustes fitting to test how well each candidate sky lines up. Their best fit, per the paper, puts the Moon and Venus 18.6 degrees apart, with the Moon about 28 percent lit. In plain English: a thin crescent, a blazing planet beside it, and a tight V of stars, all hanging over the hills at first light.

The cluster is the twist. “To my eyes, the star cluster in The Starry Night was the Hyades in Taurus. But earlier studies explained it as Aries,” Kim told Scientific American. To The Guardian he described the moment he checked the view on site: “I was standing where Vincent had stood 130 years earlier.” Rather romantic, for a man doing geometry.

The dissent, which is the good part

Not everyone is persuaded. Don Olson, the Texas State University astronomer famous for dating art and literature by the sky, told Scientific American: “The calculated position of brilliant Venus, in relation to the V shape of the Hyades asterism, does not match the painting.” The Guardian reports that the Van Gogh Museum also disputes the reading. The Associated Press carried the study, and the debate, to a wider audience. A masterpiece, darling, is allowed to keep a secret.

Why it matters beyond the museum

The question underneath is an old one: was Van Gogh painting what he saw, or what he felt? A real sky would not make the swirls literal; it would mean his imagination started from an honest observation. That is the method of every great image-maker, from a fashion photographer at a fitting to an astronomer at a telescope: look carefully first, then exaggerate with intent.

See the same sky yourself

You do not need a telescope. The Hyades are the V-shaped face of Taurus, the bull, with the orange star Aldebaran at one tip, and they climb the eastern sky after dark through late autumn and winter. Find a dark spot away from city glow; from Los Angeles, Griffith Observatory’s lawn or the high desert works, and in New York the waterfront parks are your best bet. Then go see the painting and decide whether Kim or Olson has the better eye.
