Supercooled droplets come in at chilly -43ºC with highly accurate temperature measurements

Researchers in Europe have developed a new technique to measure the temperature of tiny droplets of supercooled water with greater precision than ever before.1 As a result, they believe they may have precisely measured the coldest water droplets ever made. The findings could have implications for the future study of supercooled water, and in turn for fields such as atmospheric modelling.
