Observational anomalies challenging the Lambda-CDM cosmological model

In the current paradigm of the Lambda-CDM cosmology, the fundamental properties of the Universe are believed to be well understood, with only minor adjustment of the basic model being left to be done. The global picture of an expanding Universe originating during a singularity at Big Bang is now taken for granted, and some basic properties of the Universe are considered to be known with amazing accuracy. For instance, according to Lambda-CDM concordance cosmology, the age of the Universe is 13.798±0.037 Gyr, quoted with a precision higher than the one with which we know the age of our planet.
