A research paper published in the Monthly Notices of the Royal Astronomical Society by the researchers describes a series of large, low-frequency objects about 800 million light-years from Earth.
From time to time, radio waves from space arrive at Earth, which originates from a distant group of galaxies.
Scientists confirm that these sounds do not resemble any sound or signal heard before, and that they defy the known laws of physics.
Researchers from the University of Western Australia and the University of Bologna, Italy, used radio telescopes and X-rays to study fossil radio emissions, radio remnants and the radio corona in the Abell 3266 galaxy cluster.
Scientists had difficulty discovering these three objects, until they relied on a complex algorithm on telescope images of the cluster, and revealed evidence of a supermassive black hole.
Scientists explained that they are challenging existing theories about the origin and properties of these things, according to what was published by “The Conversation”, and found that radio waves are similar to a sound boom that is triggered by what is known as shock waves transmitted through plasma.
Scientists are also continuing work to explore and decipher the complex physics behind these radio objects.
