The team used finely ground glass particles as a binder, allowing them to avoid polymers and enhance the long-term outdoor durability of the glass. They chose the particle size to maximize the emission of infrared heat while simultaneously reflecting sunlight. Mechanical engineering Professor Jelena Srebric and Professor Zongfu Yu from the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison are co-authors of this study.

More intriguingly, it emits heat in the form of longwave infrared radiation into the icy universe, where the temperature is generally around -270 degrees Celsius, or just a few degrees above absolute zero.
