Scientists Use Radio Signals To Know The Conditions Of Planets Outside The Solar System

JAKARTA - Scientists believe radio signals emitted from several planets outside the solar system can be used to identify the character of the planet. However, so far scientists have not been able to use radio signals to search for planets that support life.

Researchers from Rice University, Houston, Texas have published the results of their research which contains several ways to identify the outer planets of the solar system that generate radio signals.

The research was co-authored by Anthony Sciola with other scientists Frank Toffoletto. They explained that the radio emission from the outer side of the exoplanet seemed maximal according to the activity of the sun. Meanwhile, radio emissions that appear from the night side tend to add to the signal significantly.

Launching SlashGear, the radio signal can be detected based on the activity that occurs in the planet's magnetosphere at night. The study also showed that radio signals from parts of the planet during the day were maximized. The reason, at that time the solar activity is very high.

Scientists are interested in a planet's magnetosphere because it shows how well the planet is shielded from the solar wind emanating from the parent star.

The magnetosphere is one of the reasons why planet Earth is habitable. The magnetosphere can protect its inhabitants from exposure to radiation and high solar winds. The strength of the magnetic field can explain the interior of the planet and allow researchers to understand the formation of the planet.

The researchers used the Titius-Bode Law to establish a linear relationship between the solar wind and radio signals from other planets. The application of the Titius-Bode Law to the outer solar system seems to have had positive results.

They also say that current analytical models only depend on the emission of light appearing in the polar regions of the exoplanet. These rays of light are referred to as aurora by us.

Recent research uses a numerical model used to predict the emission of light in the polar regions to identify the emission of radio signals originating from around the planet.

These findings allow researchers to identify exoplanets by emitting radio signals. In addition, researchers can also find out whether the outer planets of the solar system can be protected from exposure to solar radiation or not.
