I will first talk about the discovery of a pair of gigantic bubbles in our Galaxy using data from Fermi Gamma-ray Space Telescope, and the multi-wavelength observations on this so called "Fermi bubble" structure. Our numerical simulation demonstrates that the bubble structure could be evidence for past accretion events of the central supermassive black hole. I will then summarize the current state of dark matter search with Fermi data, with the focus on gamma-ray line searching from the Galactic center, galaxy clusters, and dwarf galaxies. I will explain why we got extremely excited in 2012 with a tentative gamma-ray line signal from the Galactic center. We have recently proposed to change the survey strategy of Fermi to increase the exposure at the Galactic center by more than a factor of 2. This new survey strategy has been initiated since December 2013 and will last for at least one year. I will end up with a discussion of future gamma-ray space missions.
