An article accepted for publication in the journal “Publications of the Astronomical Society of Australia” reports the first results of the EMU (Evolutionary Map of the Universe) survey, which allowed to discover several objects and phenomena. One of those phenomena is made by strange clouds of electrons surrounding two galaxies about a billion light-years from Earth. This survey was conducted using the ASKAP radio telescope and led to the cataloging of about 220,000 sources including the electron clouds that were compared to dancing ghosts due to their curious shape.
