Zooming in on the imperceptible, Sonia Leimer’s “Cosmic Dust” opens at The Cosmic House in London. Spurned by a newfound interest in microscopy, the Austrian artist deploys Dust Buddies (2023, image), a series of bronze, aluminum, and glass sculptures throughout the venue. “For an entire year, I explored a Petri dish filled with dust from the roof of The Cosmic House,” says Leimer of the micrometeoroids that inspired her. She also presents a new video about dramatic scalar shifts alongside the sculptures.
