Sixteen million light-years away, in the constellation Canes Venatici, sits a spiral galaxy that refuses to look ordinary. NASA’s Chandra X-ray Observatory recently delivered a composite view of Messier 94, also catalogued as NGC 4736, that layers high-energy X-rays over a ground-based optical photograph. The result shows a bright central region wrapped in a tight ring of intense star formation, with the whole structure set against a softer outer disk that stretches farther than early observers realized.
