Dutch Post-Impressionist canvas; Saint-Rémy window at dawn
Scientists have captured the Sun’s surface at unprecedented resolution with the Daniel K. Inouye Solar Telescope and other instruments and have identified widespread Kelvin–Helmholtz vortices—500–2,000km spirals of magnetised plasma. The team has linked these instabilities to how magnetic energy cascades to smaller scales and feeds flares and coronal mass ejections that produce space weather.
A South Korean team has linked Van Gogh's Starry Night to a predawn July 22, 1889 sky over Saint-Rémy-de-Provence, suggesting a date later than the traditional June 1889 attribution. The researchers argue the Hyades cluster and Venus align with the moon as seen from Van Gogh’s asylum window, though the museum questions the June date and notes uncertainties in the sky-matching method.
