SRON Space Research Organisation Netherlands builds and uses space instrumentation for scientific research. These look up at the Universe to study for example exoplanets and black holes, and down at Earth to monitor greenhouse gases and aerosols.
Explore the mysteries of our universe at SRON.
On 26 September, we open our doors in Leiden during NL Space Week. Discover space research through lectures, demonstrations and experiments, or try soldering your own satellite instrument.

Far-infrared, faraway exploration.
At SRON, we develop optical technologies and MKID detectors to capture some of the faintest infrared signals in the universe. For future missions such as POEMM, they help scientists study galaxy evolution and planet formation
