The Low-Frequency Array (LOFAR), the world’s most powerful radio antenna located in the Netherlands picked up signals from planets outside of Solar System.
For the first time, they detected signals from 19 distant red dwarfs.
4 of which have been recognized to have planets orbiting them.
This phenomenon hints towards the presence of hidden planets around these stars.
This technique could also answer the question if there is life in or beyond Solar System other than Earth.
