Chemical reactions taking place in outer space can now be more easily studied on Earth. Scientists discovered an efficient and versatile way of braking the rotation of molecular ions. The spinning speed of these ions is related to a rotational temperature. Using an extremely tenuous, cooled gas, the researchers have lowered this temperature to about -265 °C. From this record-low value, the researchers could vary the temperature up to -210 °C in a controlled manner.
