Mysterious Radio Signal Detected from Space

A mysterious radio signal is received on Earth from space every 54 minutes, causing scientists to sound the alarm. Something has been detected in Australia using a radio telescope that regularly sends a single pulse to Earth. The signal repeats every 54 minutes, going through three different states. The characteristics of the signal mysteriously change, contradicting the physics of neutron stars or white dwarfs. Hypotheses about a binary system and interaction between two invisible stars are being put forward. The rotation of one star around the other may possibly be causing the observed effects. Scientists are attempting to explain the phenomenon without speculating about the involvement of intelligent beings.
