Some dim and intriguing microwaves emerging from star systems outside the Milky Way might be triggered by nanodiamonds, reports a study released today by the British Nature Astronomy journal. Over the years, researchers were able to determine the luminance of such microwaves, also known as Anomalous Microwave Emissions (AME), from different parts of the Universe, but without being able to pinpoint the precise source, as reported by the study.
But a new academic research at Cardiff University in Wales has shown that microwaves are probably made from carbon crystals, the so-called nanodiamonds, found within the particles of gas and dust that encircle recently created stars.
This collection of gas and dust particles, known as a protoplanetary disk, is the place in which planets start forming and which holds a huge quantity of organic matter.
Nanodiamonds are the cause for Anomalous Microwave Emissions (AME) in the Universe
The intense temperatures within the protoplanetary disc are conducive to the development of nanodiamonds, several thousand times as small as a grain of salt and typically contained by meteorites.
“We knew that some types of particles were responsible for microwave light, but their precise source has been a puzzle since they were first detected 20 years ago,” remarked the study’s senior author, Jane Greaves, a researcher at the School of Physics and Astronomy within the Cardiff University.
“In a Sherlock Holmes-like method of eliminating other causes, we can confidently say that the best and only possible candidate capable of producing this microwave glow is the presence of nanodiamonds around these newly formed stars,” explained Greaves.
For this research, the scientists surveyed the light coming from three newly formed stars with the help of the Robert C.Byrd Green Bank telescope in West Virginia, in the United States, and the Australia Telescope Compact Array.
“This is a great and unexpected resolution to the Anomalous Microwave Emissions (AME) puzzle,” remarked Greaves.
