Another interesting result from the Canadian led team at the ALPHA collaboration, with a paper publish today in Nature in which they present the hyperfine spectrum of anti-hydrogen.

Anyone who has the least interest in either physics or astronomy is aware of atomic spectra. Over a century ago scientists discovered that each chemical element emits a signature series of wavelengths of light, which is unique to that element. From the colour of emitted light we can identify each element that is p...
