Vincent van Gogh's Starry Night may actually have taken place a month later than thought, according to a team of South Korean scientists.

The researchers say they studied the historic skies above Saint-Remy de Provence where Van Gogh painted the work and dated it to around July 22, 1889 - a month later than previously thought.

Much of the evidence revolves around when a crescent moon, as seen in the painting, would have been visible above the French town.

Scientist Elijah Jeong-hyun Kim, who led the team whose research has been published in the journal Scientific Reports, told journalists: "I am confident that July 22 is the better date. I will bet on this date."

The number of works in the permanent collection of the Louvre Abu Dhabi - up from 600 when it opened in 2017. Two hundred and forty of them are the subject of a new book, Birth of a Collection, edited by the museum's director of scientific, curatorial and collections management Guilhem Andre.

David Brognon and Stephanie Rollin have won this year's $39,000 Marcel Duchamp Prize.

The pair, who work together as Brognon Rollin, were chosen by a jury including Kader Attia and Karin Hindsbo from a shortlist of four with Joel Andrianomearisoa, Laura Henno and Josefa Ntjam missing out.

Centre Pompidou director and jury member Xavier Rey said the duo, whose work includes video, photography and sculpture, won for "a body of work that reveals an intimate dimension of the human experience with which we can all connect".

All four nominees are currently showing work in a free exhibition at the Museum of Modern Art in Paris until February 7.
