A microquasar, a smaller version of a quasar, is a compact region surrounding a stellar black hole with a mass several times that of its companion star, observable in sufficient details, in our own or nearby galaxy.[1] The matter being pulled from the companion star forms an accretion disk around the black hole. This accretion disk may become so hot, due to friction, that it begins to emit X-rays.[2] The disk also projects narrow streams or "jets" of subatomic particles at near-light speed, generating a strong radio wave emission.
