Rarely Seen Pair of Black Holes Discovered, One Unlike The Other

Scientists found a galaxy with an unusual phenomenon: two black holes, one surrounded by stars as is usually found, the other without stars around it.

Astrophysicist Julie Comerford of the University of Colorado Boulder and her colleagues discovered this rare black hole known as an intermediate-mass black hole. She presented her findings this week at the American Astronomical Society and tells Here & Now's Jeremy Hobson about her findings.
