Strange Radio Signals Rise from Deep Below Antarctica’s Ice

Scientists have detected mysterious radio transmissions emerging from thousands of miles beneath Antarctica’s ice – signals that shouldn’t be able to exist according to everything we know about physics.

The Impossible Detection

High above the frozen wasteland of Antarctica, a special balloon carrying radio equipment has detected something that shouldn’t exist. The signals appear to be coming from deep underground, traveling through thousands of miles of solid rock to reach the surface. Scientists have no explanation for what’s causing these mysterious transmissions.

The Antarctic Impulsive Transient Antenna experiment, known as ANITA, flies on NASA balloons between 19 and 24 miles above Antarctica’s icy surface. The equipment was designed to catch radio waves from outer space, but instead it has been picking up signals that seem to emerge from within the Earth itself.

These strange radio pulses hit the detector at steep angles – about 30 degrees below the ice surface. This means the signals would have had to travel upward through 3,700 to 4,300 miles of solid rock to reach the balloon. According to everything scientists know about how radio waves work, this should be impossible.

Stephanie Wissel, a physics professor at Penn State who worked on the project, explained that current scientific understanding says these radio signals should have been completely absorbed by all that rock. There’s simply no known way for them to make it through such a massive barrier of solid material.

The research team published their findings in March in the journal Physical Review Letters. Despite extensive study, they still have no answer for what’s creating these anomalous signals.

Hunting for Ghost Particles

ANITA’s main job is to hunt for neutrinos – tiny particles that have no electrical charge and almost no mass. These particles are everywhere in the universe, constantly passing through our bodies without us knowing. They come from high-energy events like exploding stars and the Sun, but they’re extremely hard to detect because they barely interact with normal matter.

The balloon experiment works by looking for special radio signals that neutrinos create when they crash into Antarctic ice. When a neutrino hits the ice, it creates a cascade of particles called an “ice shower.” These showers produce radio waves that ANITA can pick up from high above.

Sometimes neutrinos also create secondary particles called tau leptons. As these tau leptons break down, they trigger what scientists call “air showers” – another type of particle cascade that creates different radio signals. By studying these different types of signals, researchers can figure out what kind of particle caused them and where it came from.

But the mysterious signals ANITA detected don’t match either of these known patterns. The angle at which they arrived rules out the possibility that they came from neutrinos hitting the ice or from tau leptons breaking down. The signals are coming from somewhere else entirely.

Searching for Answers

To solve this puzzle, Wissel and her team analyzed data from multiple ANITA balloon flights. They compared what they found to mathematical models and computer simulations of cosmic rays and particle showers. This detailed analysis allowed them to eliminate other known sources of particle-based radio signals.

The researchers also checked with other major particle detectors around the world, including the IceCube Experiment and the Pierre Auger Observatory. They wanted to see if these other instruments had detected anything similar that might explain ANITA’s strange findings. None of the other detectors had recorded anything that could account for the anomalous signals.

The only thing the scientists can say for certain is that whatever is creating these mysterious radio pulses, it’s not neutrinos or any other particle they recognize.

Hope for Future Discovery

The mystery may not remain unsolved much longer. Wissel’s team at Penn State is building a new, more advanced detector called the Payload for Ultrahigh Energy Observation, or PUEO. This larger, more sensitive instrument should be better at detecting neutrino signals and may provide new clues about the strange Antarctic transmissions.

Wissel has some early theories about what might be causing the anomalous signals. She suspects that some unknown radio wave behavior near ice and the horizon could be responsible. Her team has explored several possibilities along these lines but hasn’t found a satisfactory explanation yet.

The physicist remains hopeful that the new PUEO detector will solve the mystery. With its improved sensitivity, it should pick up more of these anomalous signals, potentially providing enough data to finally understand their source. The new equipment might also succeed in detecting the neutrinos that ANITA was originally designed to find.

An Enduring Mystery

Until then, the strange radio signals rising from deep beneath Antarctica’s ice remain one of science’s most puzzling mysteries. Whatever is sending these transmissions from thousands of miles underground continues to challenge everything researchers thought they knew about how particles and radio waves behave in our world.
