We review the recently found large-scale anomalies in the maps of temperature anisotropies in the cosmic microwave background. These include alignments of the largest modes of CMB anisotropy with each other and with geometry and direction of motion of the solar ssystem, and the unusually low power at these largest scales. We discuss these findings in relation to expectation from standard inflationary cosmology, their statistical significance, the tools to study them, and the various attempts to explain them.

- A structure in the early Universe at z ∼ 1.3 that exceeds the homogeneity scale of the R-W concordance cosmology (2012, background): “Nevertheless, there do appear to be largescale features in the CMB that may challenge the reality of homogeneity and isotropy — see Copi et al. (2010) for a recent review.”
- Cosmology and Fundamental Physics with the Euclid Satellite (2012, background): “Also in this case the interest in such possibilities has been stimulated by several anomalies observed in the temperature WMAP maps, see [341] for a recent review (some of them were also present in the COBE maps).”
