The highly successful deep-sea telescope KM3NeT can now expand both its size and scope. Using a new type of microphone for underwater use, the telescope will attempt to detect the sound produced by neutrinos as they travel through the sea. The data collected will also be of great interest to other research…

Data from 41 million galaxies does not shake up the standard cosmological model after all. To that conclusion, to their own surprise, comes an international team of researchers including Koen Kuijken, professor at the Leiden Observatory.
