Galaxy’s gamma-ray glow may expose dark matter
Center of Milky Way produces high-energy radiation that hints at mysterious particles
GAMMA GENERATOR Gamma-ray emissions from the center of the Milky Way appear as colors other than purple in these images. The panel at right shows that when emissions from known gamma-ray sources are removed, a strong signal about 10,000 light-years across remains. A team of physicists argues that dark matter particles are responsible for those gamma rays.
