The X-ray imaging spacecraft XMM-Newton, while observing the Hubble Deep Field North,
on June 1, 2001, detected
an increased low energy X-ray emission which corresponded to solar wind ions. At the same time,
LENA observed an enhancement in the neutral solar wind. This
represents the first simultaneous observation of solar
wind ions interacting with neutral atoms in a process called 'charge exchange'.
The figure shows the data from LENA with a circle drawn to indicate the location of Earth.

Additional Information | Interstellar Wind -As the sun and solar
system move through interstellar space at a speed of 17 km/sec, atoms of
interstellar gas and dust appear to enter and leave our solar system as a
constant 'wind' of particles. | Plasma -A complex mixture of
atoms and electrically-charged particles. Typical space plasma contain
uncharged atoms, electrons, protons and ions of various atoms.
