IC 10 is a galaxy about 2.2 million light years from Earth undergoing a period of intense star formation. Observations with the Chandra X-ray Observatory reveal over 100 sources that glow in X-rays. Of these, about a dozen are systems where a black hole or neutron star is in orbit with a young, massive companion star. These systems, called X-ray binaries, are interesting because some of them could become sources of gravitational waves in the future. Astronomers using Chandra and other telescopes will continue to study X-ray binaries to better understand how they behave.
