As Fermilab commemorates #Neutrino70, the lab also celebrates its multiple generations of pioneering neutrino research. Today, Fermilab is building the next era of neutrino discovery through the world-leading @DUNEScience at @LBNFacility. news.fnal.gov/2026/07/fermil…

Happy #NeutrinoDay! Today, Fermilab is celebrating our favorite cosmic ghosts with @SanfordLab at their annual science festival! As we celebrate #Neutrino70, we are proud to build @DUNEScience alongside our incredible community and global partners. lbnf-dune.fnal.gov.

Fermilab crews have successfully placed the first beamline component in the tunnel that will house the powerful new @PIP2accelerator, marking a major milestone for the lab’s future neutrino research program. news.fnal.gov/2026/07/fermil…

Neutrinos leftover from the Big Bang exist everywhere in the universe. But because they are very low-energy particles, these neutrinos are also nearly impossible to detect. neutrinos.fnal.gov/sources/big-ba… #Neutrino70

Neutrino observatories will be the first places on Earth to see a supernova and can be used to direct optical telescopes to the right part of the sky to witness the arrival of the supernova’s light. Learn more at neutrinos.fnal.gov/sources/supern… #Neutrino70

#DidYouKnow? All neutrinos are left-handed, while all antineutrinos are right-handed. Scientists at @Fermilab study the differences between them to help answer one of the biggest questions in science: Why does our Universe exist at all? #Neutrino70

An antineutrino is thus simply an “opposite version” of a neutrino. But if one of the main ways matter and antimatter are opposites is charge, then could neutrinos and antineutrinos be the same thing? Scientists aren’t sure. Learn more at neutrinos.fnal.gov/types/antineut… #Neutrino70

The sun is the source of most of the neutrinos that are passing through you at any moment. Learn more at neutrinos.fnal.gov/sources/solar-… #Neutrino70

Neutrinos can come from within Earth’s core, our sun, explosions of far-off stars, the Big Bang, reactions when particles interact in our atmosphere, or even reactions in your own body. youtu.be/RvNTnvQMEM8?si… #Neutrino70

@DUNEScience Here’s to the next frontier of discovery, powered by the same spirit of exploration that has defined our nation for 250 years. 🎆🇺🇸 #America250 #Neutrino70 #DUNEscience #STEM #July4th

Through leading landmark projects like @DUNEscience and the US contribution to the #HiLumiLHCupgrade, using the #GenesisMission to accelerate discovery and driving advances in #QuantumComputing, we aren't just studying the future of science — we are building it.

Happy 250th Birthday, America! 🇺🇸✨ Today, as we look back at two and a half centuries of curiosity, innovation and the relentless pursuit of the unknown, we at Fermilab are simultaneously celebrating another meaningful frontier.

Neutrinos are tricky to study because they only interact via gravity and the weak force. To increase the odds of seeing them, scientists build huge detectors and create intense sources of neutrinos. Learn more at neutrinos.fnal.gov/whats-a-neutri… #Neutrino70

While we know neutrinos do have mass (thanks to their ability to change flavors as they travel), we still don't know their exact weight. neutrinos.fnal.gov/mysteries/mass/ #Neutrino70

Neutrinos come in three distinct flavors: electron, muon, and tau. Scientists "see" a neutrino by looking for their partner particles (electrons, muons, or taus) that get made when a neutrino finally interacts inside a detector. neutrinos.fnal.gov/types/flavor/ #Neutrino70

Congratulations to the @PIP2accelerator team!

@BerkeleyLab It will ultimately power the world’s most intense neutrino beam for @DUNEScience, helping scientists unlock the deepest mysteries of the cosmos. Learn more at pip2.fnal.gov @LBNFacility

The first piece of the new linear accelerator’s beamline arrived in the accelerator tunnel! This radio-frequency quadrupole — designed and built by our partners @BerkeleyLab —will serve as the "first gear" of the upgraded Fermilab accelerator complex. #Neutrino70
