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.
