An X-ray picture of the bright supernova remnant SN1006
This false color composite picture of the bright supernova remnant SN1006
was taken with the CCD cameras aboard the Advanced Satellite for Cosmology and
Astrophysics (ASCA). The supernova remnant was formed after a star in
our Galaxy exploded. The expanding gas from the star is colliding into the
surrounding material. This collision produced a violent shock which
generates X-ray light. The bright regions in the picture shows the
locations of this shock along the rim of the remnant. The
energy spectrum of the bright 'caps' provides compelling evidence that
cosmic-rays are produced in supernova remnants.
The picture was processed at NASA's
Goddard Space flight Center, which supplied ASCA's telescope mirrors;
the CCD cameras were developed at MIT, and the satellite was launched and is
managed by the Institute
of Space and Astronautical Science in Japan.
