Description The NPS is a region of strong diffuse X-ray emission extending in an arc from
l,b =25deg,10deg to 330deg,75deg. Conventional wisdom says that the NPS is the
limb-brightened edge of the Loop I superbubble, roughly centered on, and likely
powered by the Sco-Cen OB association, placing it at a distance of 100-200 pc.
However, it has also been seen as a supershell centered on the Gal. center, and
the implications for the plasma and energy involved are extreme. We propose to
determine the location of the NPS using a series of overlapping observations of
the southern terminus. Comparison with the Gal. distribution of X-ray absorbing
material will allow us to determine if it is absorption bounded, and by which
ISM features, thus revealing its distance.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
