Electrons are typically seen flitting around their atoms, but a team of physicists has now imaged the particles in a very different state: nestled together in a quantum phase called a Wigner crystal, without a nucleus at their core.

A team of physicists in Germany managed to create a time crystal that demonstrably lasts 40 minutes—10 million times longer than other known crystals—and could persist for even longer.
