Take the classic piano tuner question. To solve it, you might start by estimating Chicago’s population (say, 3 million). Then, you’d guess how many households own pianos (maybe 1 in 5).

Discover the Fermi Paradox — why, in a vast universe full of stars and planets, haven't we found extraterrestrial life? Explore the theories behind this great mystery.

The Fermi bubbles rise above and below the center of the Milky Way. They stretch across 50,000 light-years—about half the width of our entire galaxy. They were first detected in 2010 through ...

Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds—or Fermi bubbles—at the Milky Way's center. The finding challenges current models of Fermi bubble ...

It was a simple question asked over lunch in 1950. Enrico Fermi, the Nobel Prize-winning physicist who helped usher in the atomic age, was dining with colleagues at Los Alamos, New Mexico, when ...
