January 1964: 'Black holes'
The term gains wider use after it appears in articles in the Science News Letter (January 18) and Life magazine (January 24). In simplest terms: "A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying." (Definition from NASA)
