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 [[Binary star#Cataclysmic variables and X-ray binaries|companion star]], observable in sufficient details, in [[Milky Way|our own]] or nearby galaxy.<ref name="a">{{cite web|title=First Microquasar Found Beyond Our Milky Way|url=http://www.nrao.edu/pr/2012/microquasar/|website=www.nrao.edu|accessdate=19 January 2017}}</ref> 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-ray]]s.<ref name="b"/> The disk also projects narrow streams or "[[Astrophysical jet|jets]]" of subatomic particles at near-[[Speed of light|light speed]], generating a strong [[radio wave]] emission.
