We discuss laser cooling of antihydrogen atoms in a magnetic trap down to the millikelvin range using radiation at Lyman-alpha. This is very important to suppress residual Zeeman shifts and broadenings in future high-resolution laser-spectroscopy of antihydrogen. Even colder antihydrogen temperatures in the sub-millikelvin range are desirable for experiments on antimatter gravity. We discuss novel methods to obtain antihydrogen atoms at these ultracold temperatures.
