I will present the first cosmological parameter constraints from the Kilo Degree Survey (KiDS), an ongoing ESO survey that studies the growth of structures and the expansion history of the Universe using weak gravitational lensing. Interestingly our analysis finds a low-redshift universe that is rather different from the predictions of the Planck CMB experiment. I will discuss whether this tension could arise from systematic uncertainties in either probe, or whether it is evidence for a Universe that is more exotic than the standard LambdaCDM model.
