Chandra
X-ray image of the pulsar wind nebula or "plerion" (shown
as a blue nebulosity) associated with pulsar PSR B1509-58 (bright
white spot) in supernova remnant SNR G320.4-1.2 - the result of
an exploded star. The word "plerion"
is- derived from the Greek word "pleres" to indicate
that the pulsar wind nebula is "filled" by energetic
particles streaming from the tiny rotating pulsar. This wind is
probably confined by the thermal nebula at the top (red/yellow
colours), but escapes more freely towards the bottom left along
the southern pulsar jet.
There are many such plerions in our galaxy (the Crab Nebula is also a plerion) and H.E.S.S. will be searching for very high energy gamma-rays from a number of these systems.
