Australian researchers have discovered hidden planets using radio waves, the Massachusetts Institute of Technology (MTI) writes.
An astronomer at the University of Queensland noticed unexpected radio waves from stars that hinted at the presence of previously unknown planets. The research team made the discovery using a Dutch radio telescope network that is one of the largest in the world and can cover an area of 300,000 square metres.
This discovery is an important step for radio astronomy, and may also lead to the discovery of new planets across the galaxy. We’ve known for a long time that planets in our solar system emit powerful radio waves as their magnetic fields interact with the solar wind, but radio signals from planets outside our solar system have yet to be detected.
University of Queensland astronomer Benjamin Pope said, adding that signals from 19 distant red dwarfs have also been detected, in four cases due to the presence of planets orbiting them.
At the same time, more research is needed to confirm and analyze the existence of the newly discovered planets, some of which are 165 light-years away from Earth.
