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.
