In the galaxy NGC 300, in the constellation Sculptor
15 times the mass of the Sun
Diameter about 45 miles (75 km) roughly equal to the size of a large county
An artist's concept of the NGC 300 X-1 system, showing the massive star dumping gas onto the black hole. The gas forms a small but extremely hot disk. Some of the material is funneled into strong "jets" that shoot away from the poles of the black hole. The companion star also produces strong "winds," surrounding the star with a cloud of gas.
