I suggest that it is probably possible to detect signals in exoplanets ionospheres
They should work towards machines capable of those magnetic detections in ionospheres, And Im sure through Spectroscopy they would be able to find them. Similar to how they detect the atmosphere already in exoplanets with spectroscopy. I believe they can make detectors capable of doing that
If anyone knows of any articals or studies on this topic that I mention can you please share. Havn’t seen much on this subject myself. I just kind of Theorized it and figure its probably possible if they Experiment down this path to finding Signals this way.
in 2022 researchers may have just made the first detection of an exoplanet through radio emissions created by the planet’s aurora.
Planets emit radio signals created from interactions between their magnetic fields and the plasma or “solar wind” radiating from their parent stars. When plasma from a star becomes entangled in the magnetic bubble around a planet - the [magnetosphere] – visible aurora is created just like the Northern/Southern Lights we see on our own planet. Aurora also creates radio emissions that travel light years through space.
The phenomenon of “bouncing” or refracting radio signals off the ionosphere, allowing long-distance communication, is a key aspect of how shortwave radio waves (high-frequency) travel beyond line of sight
- What is the Ionosphere?
The ionosphere is a layer of Earth’s upper atmosphere containing a high concentration of free ions and electrons, influenced by the sun’s radiation.
analyzing the exoplanet’s atmosphere to search for key indicators like water, or methane, and other potential biosignatures
Exoplanet atmosphere spectroscopy involves analyzing the light passing through an exoplanet’s atmosphere during transit, a technique that reveals the composition and structure of the planet’s atmosphere by observing how different wavelengths of light are absorbed
