X-ray, Optical & H-alpha Images of NGC 7793
Combining observations made with NASA's Chandra X-ray Observatory and ESO's Very Large Telescope, astronomers have uncovered the most powerful pair of jets ever seen from a stellar black hole. This object, also known as a 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.

Labeled X-ray Close-up
X-ray data reveal a "microquasar" in the galaxy NGC 7793. This system contains a stellar-mass black hole that is being fed by a companion star, The faint green/blue source near the middle of the Chandra image corresponds to the position of the black hole, while the red/yellow (upper right) and yellow (lower left) sources correspond to spots where the jets are plowing into surrounding gas and heating it.

A Stellar Black Hole Illustration
Combining observations done with ESO's Very Large Telescope and NASA's Chandra X-ray telescope, astronomers have uncovered the most powerful pair of jets ever seen from a stellar black hole. The black hole blows a huge bubble of hot gas, 1000 light-years across or twice as large and tens of times more powerful than the other such microquasars. The stellar black hole belongs to a binary system as pictured in this artist's impression.
