Farmers' picnic

Just inside the site boundary, secluded from most of Fermilab, sits Leonard Baumann's rickety red barn. Baumann, like 55 other farmers, relocated 40 years ago to make way for the construction of Fermilab.

A tale of dark energy

In the 1990s, astronomical observations revealed that the expansion of the universe is accelerating. Not knowing what causes this acceleration, scientists began to attribute the phenomenon to some unknown source of energy, coined "dark energy" by astrophysicist Michael Turner.

PET scan

Scientists have sought to create better medical imaging techniques ever since Wilhelm Röntgen’s 1896 discovery that X-rays can reveal bones and other anatomical structures in a noninvasive way.
