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.
