I will first talk about the discovery of a pair of gigantic bubbles in our Galaxy using data from Fermi Gamma-ray Space Telescope. This so-called "Fermi bubble" structure could be evidence for past accretion events of the central supermassive black hole. Then I'll summarize the current status of dark matter search with Fermi data, with the focus on the earlier claimed line emission at 130 GeV and the diffuse gamma-ray excess at ~GeV.  I will end up with a discussion of future gamma-ray space missions, especially our recent proposal of a dedicated gamma-ray satellite mapping the sky from ~10 MeV to ~1 GeV, with much improved PSF and the capability of polarization measurement. This mission, besides many other science goals, will help us to resolve the Galactic center in a crucial energy region to search for dark matter annihilation signal.
