This seminar will cover a few highlights of the IceCube Neutrino Observatory physics program. Recently a high-energy component of astrophysical origin has been discovered in diffuse searches for neutrino events of all flavors. This observation indicates a harder flux component than what expected from atmospheric interactions. Several studies are ongoing to identify the origin of such neutrinos through point-like, extended, time-dependent and stacking cosmic sources. IceCube is also looking for evidence of dark matter annihilation in the Sun, the galactic centre and halo and other massive sources. With its denser core, IceCube produces interesting results that complement those of direct and indirect searches. Future detector extensions are being planned both at the higher and lower edges of the current energy range.
