"Last night the city of Leiden was a remarkable experiment: SEEING STARS Leiden. In the wide vicinity of the Leiden Observatory, all the lights were turned off by thousands of citizens. Although it was cloudy, we suddenly saw Saturn and other stars in the historical streets of Leiden. It was so mysterious to walk with so many people in a dark city. I felt like an astronaut on Earth.” - Daan Roosegaarde

It’s official: The city of Leiden will switch off its city lights on September 25 between 22.00 till 23.30 to see the stars together. Lights off, stars on. All citizens of Leiden are encouraged to participate. SEEING STARS Leiden is accompanied with a cultural and citizen science program as part of the Leiden European City of Science 2022.

TOUCH transforms museum Draiflessen Collection into an ephemeral dream world of light through the joining of hands.

What was until recently a completely everyday, self-evident act of human encounter is suddenly no longer so: the mutual touch, the embrace or the handshake. Roosegaarde addresses this moment and the significance of this human connection in his expansive installation developed especially for the Draiflessen Collection.

In the museum's 4,300 m3 exhibition space, Roosegaarde has created TOUCH, an interactive work of art that captivates visitors as they enter, creates a sense of wonder, and invites and inspires them to act without words. The fact that our perception and action are specifically directed towards this special act of connection unravels at the very moment of touch: this is the key to an imposing visual explosion that transports us and our counterpart into a new universe when the artwork’s electronic field senses when two visitors join hands and through this interaction, light is then coded into thousands of star lights.

28.11.2021 until 27.02.2022 in Mettingen, Germany.
