On Earth's nightside,
magnetic reconnection happens in the magnetotail, where magnetic flux tubes originally disconnected on the dayside are reconnected.

If the solar wind field
happens to be oriented in the opposite direction to a field in the Martian surface, the two fields join together in
magnetic reconnection.
The way
reconnection disturbs terrestrial power grids is complex but, in essence, the process mimics what
happens in electric generators, where a fluctuating
magnetic field (usually a moving magnet) produces a current in a coil of wire, says Adam Szabo, director of NASA's Heliophysics Laboratory.
To see whether these are generated by the same process as
happens on the sun — the breaking and
reconnection of
magnetic fields (pictured above)-- astronomers studied light from 100,000 stars using China's Guo Shouiing Telescope.
Much of what
happens in those situations is related to
magnetic reconnection, which can accelerate particles to high energy and is the force driving solar flares towards earth.
Spacecraft observing
magnetic reconnection have noted a fundamental gap between most theoretical studies of the phenomenon and what
happens in space.
