This artist's rendering shows the most powerful pair of jets ever seen from a stellar black hole. This microquasar blows a huge bubble of hot gas 1,000 light-years across – twice as large and tens of times more powerful than other known microquasars. Scientists at the European Southern Observatory spied a pair of gigantic bubbles of hot gas coming from a stellar black hole, about 12 million light-years from Earth, as pictured in this artist's rendering from the observatory. The bubbles are the most powerful microquasars seen by astronomers, according to a study published in the journal Nature.
