Temperatures as low as 20 nK (a nanokelvin is 10-9 K) have recently been produced in a group of some 2000 rubidium atoms (Rb, chosen for its optical and magnetic properties). This is the lowest kinetic temperature ever achieved. Find out more at http://www.sun.rhbnc.ac.uk/~uhap057/LTWeb/Absolute.html.
