“Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe. While studying the distant galaxy cluster known as SpARCS1049, astronomers detected faint mysterious radio waves, according to a study published in The Astrophysical Journal Letters and available on the pre-print server Xrxiv. The discovered radio waves, which took 10 billion years to reach Earth, originated from a vast region of space filled with high-energy particles and magnetic fields. These vast clouds of high-energy particles are known as a mini-halo. A mini-halo has never been detected this deep into space before, according to the study. Mini-halos are described in the study as faint groups of charged particles. These groups are known to emit both radio and X-ray waves. Mini-halos are typically found in clusters between galaxies.” (06/28/25)
