Spinning pyramid-shaped nanodiamonds may solve a space mystery (not pictured) Getty
They may be tiny, but nanodiamonds shaped like pyramids may have solved a big mystery that鈥檚 puzzled astronomers since 1996. That鈥檚 when researchers noticed something weird when analysing data from the COBE satellite, which was launched in 1989 to capture cosmic background radiation left over from the big bang.
COBE saw the expected background radiation, but it also captured emissions of microwaves whose source couldn鈥檛 be explained. With wavelengths of a centimetre or so, and frequencies of 10 to 60 gigahertz, the 鈥渁nomalous microwave emission鈥 has puzzled…
