Solar-B

"The Solar-B mission is a follow-on to the highly successful Japan/US/UK Yohkoh (Solar-A) satellite which operated between 1991 and 2001. Led by the Japanese Aerospace Exploration Agency's (JAXA) Space Science Research Division (formerly the Institute of Space and Astronautical Science (ISAS)), Solar-B consists of a coordinated set of optical, EUV, and X-ray instruments that will investigate the interaction between the Sun's magnetic field and its corona.

Goodrich Technology Launches On Board Japan Aerospace Exploration Agency Solar Physics Satellite 'Solar-B'
The Japan Aerospace Exploration Agency (JAXA) recently launched its latest solar physics satellite, dubbed "Solar-B," with Goodrich Corporation's (NYSE: GR) Solar X- ray Telescope (XRT) mirror on board. The satellite's three-year missionis to explore the magnetic fields of the sun, resulting in an improved understanding of the mechanisms that power the solar atmosphere and drive solar eruptions.
"Goodrich is proud to have played an important role in providing
advanced X-Ray mirror technologies in support of this valuable mission,"

Using new orbiting observatories, astronomers have now cataloged about 100,000 quasars. So ideas about them are bound to evolve in the coming decades as astronomers look at and analyze all this data. The current most popular theory about quasars suggests that each one is a supermassive black hole -- a million to a billion times more massive than our sun -- at the heart of a newly forming galaxy. These quasar black holes might have formed with their surrounding galaxies from evenly distributed gas filling the early universe
