Over the past few decades, the cameras of CMB experiments have evolved from containing just hundreds of sensors to containing tens of thousands. CMB-S4, however, is aiming for half a million, which will provide unprecedented sensitivity—detecting nanokelvin fluctuations in the CMB, which has a measured average temperature of around 2.713 Kelvin—and position scientists to learn more from the CMB than ever before.

This new temperature is six times lower than the previous record and marks the first time a gas was cooled below one nanokelvin (one billionth of a degree). At absolute zero (-273? Celsius or -460? Fahrenheit), all motion stops, except for tiny atomic vibrations, since the cooling process has extracted all energy from the particles.

This new temperature is six times lower than the previous record, and marks the first time that a gas was cooled below 1 nanokelvin (1 billionth of a degree). At absolute zero (-273 deg Celsius or -460 deg Fahrenheit), all motion stops, except for tiny atomic vibrations, since the cooling process has extracted all energy from the particles. By improving cooling methods, scientists have succeeded in getting closer to absolute zero.

"To go below one nanokelvin is a little like running a mile under four minutes for the first time," said Nobel laureate Wolfgang Ketterle, co-leader of the team. Ketterle is MIT's John D. MacArthur Professor of Physics.

Zwierlein explains: “For us, these effects occur at nanokelvin because we are working with dilute atomic gases. If you have a dense piece of matter, these same effects may well happen at room temperature.”
