Black Hole Blast Shapes Structure: Astronomers trace ‘Treble Clef’ origins; collision revives radio glow

Astronomers have traced the origins of an unusual cosmic formation resembling a musical treble clef to an ancient black hole eruption and a subsequent collision between two galaxy clusters. According to NASA’s Chandra X-ray Observatory and a study published in Astronomy & Astrophysics, the discovery offers fresh insight into how violent events can reshape enormous structures across the universe. The formation, nicknamed the “Treble Clef” because of its distinctive appearance in radio observations, had long presented a challenge to astronomers. Its location behind the plane of the Milky Way makes it difficult to observe, as foreground stars, gas and dust obscure much of the region. By combining observations across multiple wavelengths, researchers were able to piece together a possible explanation for its unusual shape.A cosmic formation hidden behind the Milky WayThe research, led by Andrea Botteon of Italy’s National Institute for Astrophysics (INAF), brought together data from NASA’s Chandra X-ray Observatory, the European Space Agency’s eROSITA telescope, the LOw Frequency ARray (LOFAR) radio telescope network and the United Kingdom Infrared Telescope (UKIRT).The observation...
