The timeline below accompanies this main story: Sterile neutrinos leave ghostly fingerprints on cosmos
↑ 1985: Observations of how radioactive tritium decays show hints of a
↓ 1991 – 1993: Experiments rule out a neutrino of that mass
↑ 1993 – 1998: The Liquid Scintillator Neutrino Detector (LSND) at Los Alamos National Laboratory in New Mexico sees muon antineutrinos morph into electron antineutrinos at a based on previous experiments. An intermediate, sterile antineutrino phase could explain the observations

↑ 2010: MiniBooNE runs an experiment more closely resembling LSND’s setup and . To explain the effect, though, two types of sterile neutrinos are needed
↑ 2011: Physicists in France claim that nuclear reactors are . They say the missing may have morphed into sterile antineutrinos
