Telescope arXiv arXiv: 1010.2752v1 Analyzing old data from the
Fermi Gamma Ray Space Telescope, the authors have noticed gamma
ray emissions consistent with predictions for a certain type of
dark matter. Unfortunately, these things are never nice, clear
problems where they’ve definitely seen dark matter or have
definitely not seen it, but it’s an exciting collection of data
points for astrophysicists who are on the dark matter hunt. It
could turn out to be the evidence that people have been looking
for, but it’s too early to say anything definitively. Weighing
