New Scientist (United Kingdom, Oct. 22) -- NASA’s Fermi space telescope has seen signs of high-energy photons around the supermassive black hole at the center of the Milky Way, where dark matter is expected to cluster. Some think it is our best sign of dark matter so far. Jessie Shelton, an assistant professor of physics at Illinois, and her colleagues argue that if the signal is truly from dark matter, it is an order of magnitude too weak to match up with conventional ideas of how the black hole formed.
