  Dark matter (DM) comes from long-range gravitational observations, and it is
considered as something that does not interact with ordinary matter or emits
light. However, also on much smaller scales, a number of unexpected
observations of the solar activity and the dynamic Earth atmosphere might arise
from DM contradicting the aforementioned DM picture. Because, gravitational
(self) focusing effects by the Sun or its planets of streaming DM fit as the
interpretation of the otherwise puzzling 11-year solar cycle, the mysterious
heating of the solar corona, atmospheric transients, etc. Observationally
driven, an external impact by overlooked streaming invisible matter reconciles
the investigated mysterious behavior showing otherwise unexpected planetary
relationships; this is a signature for gravitational focusing of streaming DM
by the solar system bodies. Then, focusing of DM streams could also occur in
exoplanetary systems, suggesting for the first time the carrying out of
investigations by searching for the associated stellar activity as a function
of the exoplanetary orbital phases.
