North Polar Spur
The North Polar Spur - perhaps the most spectacular coherent structure in the soft X-ray sky - has been completely mapped for the first time at high resolution in the ROSAT/PSPC survey. The North Polar Spur is part of a hot interstellar bubble created by winds of young, hot stars and several supernova explosions.
