  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 System, 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.
