Strange radio waves detected under ice of Antarctica, scientists are still searching for sources
A team of researchers working in Antarctica have detected abnormal radio signals that emerged deeply under snow. These waves were raised during an experiment using the Antarctic impulsive transient antenna (Anita), which is a NASA-funded project. High energy particles from space. The discovery was unpredictable because the signals were coming from the bottom of the surface instead of the space. Scientists say the waves are unlikely to be caused by known particles such as neutrino and yet not yet determined what their production is.
Radio waves were found during neutrino search in Antarctica
Anita usage Using a balloon, high-energy was designed to study neutrino that took radio devices into a stratosphere. Antarctica was chosen as a site due to its separation and low intervention from other radio sources. When searching for neutrinos, researchers came in signs coming from about 30 degrees from the snow surface. These signs were unpredictable because they had to undergo a rock of thousands of kilometers that they should have completely absorbed.
Neutrino rejected as a cause
Stephanie Visel, an astronomer physicist at Pen State University and Anita team, said that signals were not in line with neutrino. It is incredibly difficult to detect neutrino and rarely interact with the case. Although they can travel great distance through solid rocks, do not match the nature of angles and signals what scientists expect from neutrino interactions. The team also cross-checked its findings along with the data of two other experiments and did not find a match confirming that it was not a neutrino event.
Principles and unanswered questions around mystery
Since neutrino was rejected, scientists are now considering other explanations. Some have proposed that indications may be related to dark matter or unknown radio wave behavior around the ice and horizon. However, none of these principles have been confirmed. Visel said that when he has discovered many ideas, no one fully explains what was revealed. He said that more use and data will be required to understand what is happening under the Antarctic ice.
Search for mysterious source continues
The devices used in the experiment were removed at a distance of about 40 kilometers in the sky to capture unconscious radio emissions. While this approach allows for a comprehensive approach to signs that enter the Earth from space, it also reveals unexpected activity from the bottom. As scientific data continue to review and prepare for future missions, they expect more exposure to the nature of these strange signals. For now, the source of radio waves remains a mystery.
