DXRBS' unique combination of a dual X-ray/radio survey method and high sensitivity has opened up important, large new regions of parameter space for both blazar sub-classes, within which a large fraction of our sample (nearly 50%) lie. This section is devoted to discussing these discoveries and their impact upon our understanding of the blazar class. љ . FSRQs . BL Lacs . Paolo Padovani . 1/5/1998

. A "radio phoenix" has been discovered using X-ray, radio, and optical data. This system contains the collision of two galaxy clusters located about 1.6 billion light years from Earth. The collision re-energized a regeneration of vast clouds of high-energy particles that primarily radiate at radio frequencies. Understanding how galaxy clusters grow over time, including through collisions, is important for cosmology. X-ray: NASA/CXC/Univ of Hamburg/F. de Gasperin et al; Optical: SDSS; Radio: NRAO/VLA

spaceweb@oulu.fi - last update: 20 November 1998, 1440 UT (RR) . The 'space weather' have been coined to point out that many of the phenomena studied in space physics have also important practical consequences (e.g., Davenport, 1996). In addition to the geomagnetic activity , also changes in the atmosphere , or even comets and man-made debris in space, can be of importance. ... The other serious consequence of bad space weather is the possibility of damage to Earth orbiting satellites. ...
