A Microquasar


This is SS 433, a microquasar located about 18,000 light-years away in the constellation Aquila. This image at submillimeter wavelengths is special because it shows the jets emitted by a hot, swirling disc of material around the black hole at SS 433’s center. The jets’ corkscrew shapes are created by a phenomenon known as precession. The two jets are slowly wobbling about their spin axes in the same manner as a spinning top as it slows down. The corkscrew is enormous—5000 times the size of the Solar System.
