Number 130 (Story #2), May 27, 1993 by Phillip F. Schewe and Ben Stein THE INTERSTELLAR SPACE THAT SURROUNDS OUR SOLAR SYSTEM is an elongated, misshapen region of low-density gas, according to ultraviolet measurements made by the ROSAT satellite and Extreme Ultraviolet Explorer. The measurements, presented by Barry Y. Welsh of NASA at an astrophysics meeting in the Netherlands earlier this month, put to rest speculations that the shape of this low-density void resembles a single bubble carved out by a lone supernova explosion millions of years ago. Fred Bruhweiler of Catholic University has proposed that the region as it is now mapped out could have resulted from a combination of several supernova explosions or strong stellar winds.
