Default Anomaly Large Cold Spot and an Asymmetry in Temperatures on Opposite Hemispheres of the Sky

This graphic highlights anomalies seen in the Planck data. One Anomaly
is an Asymmetry in the Average Temperatures on Opposite Hemispheres of
the Sky (indicated by the curved line), with slightly higher average
temperatures in the southern ecliptic hemisphere and slightly lower
average temperatures in the northern ecliptic hemisphere. This runs
counter to the mainstream view that the universe should be broadly
similar in any direction we look. There Is Also a Cold Spot that
Extends Over a Patch of Sky That Is Much Larger Than Expected
(Circled). The anomalous regions have been enhanced here to make them
more clearly visible.

Do you have any ideas of cause of these anomalies?

Interesting.
The first thing that comes to mind is that the MBR is assumed to be
residual from the Big Bang, which is strictly hypothetical. So MBR may be
caused by something else.
It is assumed to be greatly redshifted radiation residue from the birth of
our universe, but it could also be thermal radiation that permeates the
not-so-far-away universe.
That the anomalies follow the ecliptic is hardly a coincidence, and it is
unlikely to be a feature of the distant past or distant universe, but more
probably of our very near surroundings. Then, if this is truly so, the MBR
is just MR, with no direct indication that it's redshifted at all, and we'd
have to start looking for what causes it, and why it seems related to the
ecliptic.
I find it hard to believe that the anisotropy matches the ecliptic for no
reason. This makes one of the main evidences of the Big Bang, in fact, a
contradiction. Likely, new Big Bang models will be built to explain this,
but I would try a new approach and start looking for another possible cause
for the M(B?)R.
