They discovered that the lobe, an area of the magnetosphere which is usually filled with cold, unenergetic, plasma, does in some cases fill up with hot plasma when
magnetic reconnection occurs on the night side of the Earth, thus closing the field lines and trapping the plasma within.
Auroras are a consequence of the solar wind penetrating the magnetopause when
magnetic reconnection occurs.
When
magnetic reconnection occurs between two clouds of plasma that have the same density, the exhaust flow is wildly unstable — flapping about like a garden hose with too much water pressure.

Space Physicists led by Lancaster University used data to show that Cassini had passed through the region at Saturn where
magnetic reconnection was
occurring, which has never before been observed.
The team found that a process called «
magnetic reconnection» must have a big role in creating the Martian magnetotail because, if
reconnection were
occurring, it would put the twist in the tail.
«We found that the energetic plasma signatures
occur on high - latitude
magnetic field lines that have been «closed» by the process of
magnetic reconnection, which then causes the plasma to become relatively hot,» says Dr Fear.
Due to launch in late 2014, MMS will investigate how the sun and Earth's
magnetic fields connect and disconnect, explosively transferring energy from one to the other — a fundamental physical process that
occurs throughout the universe, known as
magnetic reconnection.
