Astronomers reveal the source of strange glow in our Milky Way galaxy

A strange glow emerging from within our Milky Way galaxy may be due to the reason that space consists of a large number of diamonds. This is the inference drawn by a recent study undertaken by a team of researchers in an effort to understand the thin series of microwaves, which are found surrounding distant stars. According to the reports of the study, the strange glowing jets coming from some parts of our Milky Way galaxy are due to the presence of diamond dust.

Previously, the astronomers knew that there are certain tiny swiftly spinning objects in space producing this faint trace of light called Anomalous Microwave Emission (AME). However, the researchers had not completely understood the reason behind this glowing light till now.

As a part of this study, the scientists made use of the Green Bank Telescope in West Virginia as well as the Australia Telescope Compact Array for searching the Anomalous Microwave Emission in fourteen newly evolved star systems in our Milky Way galaxy. In three out of these fourteen star systems emissions were detected to be getting generated from disks of gas and dust surrounding stars.

A co-author of the study, David Frayer at the Green Bank Observatory, said in a statement, “This is the first clear detection of anomalous microwave emission coming from protoplanetary disks.”

In these three star systems, the researchers also discovered distinct infrared-light traces of nanodiamonds, which are basically crystals of carbon way smaller in comparison to sand grains. The lead author of the study, Jane Greaves at the Cardiff University in Wales, said that these traces of infrared-light are so uncommon that “no other young stars have the confirmed infrared imprint.”

Further, Greaves explained, “In a Sherlock Holmes-like method of eliminating all other causes, we can confidently say the best candidate capable of producing this microwave glow is the presence of nanodiamonds around these newly formed stars.”

These new inferences drawn from the study conducted lately is expected to help the scientists in a better understanding of the early days of the universe. The astronomers previously believed that the universe grew even faster in comparison to the velocity of light immediately after the Big Bang in some course of “cosmic inflation.” However, if an event like this would have occurred then that would have left behind an identifiable imprint, which is a characteristic odd polarization in the “cosmic microwave background.”

A co-author of the study, Brian Mason at the National Radio Astronomy Observatory at Charlottesville in Virginia, said that this recent study gives “good news for those who study the polarization of the cosmic microwave background since the signal from spinning nanodiamonds would be weakly polarized at best.”
