What can our cosmic neighbors tell us about dark matter and the early universe?

It’s the cornerstone of cosmology, but what is it all about?

Tooting our horn: Fermilab has the most expertise in constructing neutrino horns, which focus the particles that eventually decay into neutrinos. Learn how they work.

A doctoral student and his adviser designed a tabletop particle detector they hope to make accessible to budding young engineering physicists.

Fermilab’s house photographer of almost 30 years, Reidar Hahn, shares four of his most iconic shots.

Fermilab’s TRAC program helps middle and high school teachers turn lab experiences into lessons or exercises for their students.

How do scientists know what percentages of the universe are made up of dark matter and dark energy? Cosmologist Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology explains. Watch the 3-minute video.

NOvA scientists have seen evidence that one of the three neutrino mass states might not include equal parts of muon and tau flavor, as previously thought. Scientists refer to this as “nonmaximal mixing,” and NOvA’s result is the first hint that this may be the case for the third mass state.

What’s it like to be part of an experiment collaboration in the weeks and days before a big announcement?

Possible signs of new particle seem to have washed out in an influx of new data.
