Neutrinos, the mysterious and nearly massless particles that barely interact with anything, are revealing new secrets through the KATRIN experiment.

Using tritium decay and advanced spectrometry, KATRIN has slashed the upper limit on neutrino mass, pushing our understanding of fundamental physics into new territory. With 250 days of data already analyzed and more to come, researchers are optimistic about uncovering even more surprises. Future upgrades aim to detect hypothetical sterile neutrinos, potential dark matter candidates, and possibly revolutionize our view of the universe’s invisible side.
