Microquasar SS 433 (2004)
A microquasar (such as SS 433 in Aquila), as its name suggests, is a little like a
miniature quasar. They are X-ray binary stars in which a normal star is being 'eaten'
by a black hole or, sometimes, a neutron star. A disc of matter surrounds the black
hole or neutron star, and jets of high-speed particles are blasted out of the centre
of this disc by processes that are not that clearly understood.
