It still bathes the Earth in a near-uniform glow at microwave frequencies, and has a temperature profile that is just 2.7 degrees above absolute zero.

Add a few circuits with a pinch of software and the sensor-only camera can produce up to ten images per second, but the catch is Duke's only works at microwave frequencies.

With the new method in hand, Dr Davis said that next-generation telescopes tuned to these microwave frequencies - such as the Alma telescope in Chile - would be able to easily acquire the masses of hundreds of black holes.
