Wolk Astronomers have used NASA's Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the "Treble Clef" because its distinct shape strongly resembles the musical symbol.
An explanation for the Treble Clef has been particularly difficult to find because the formation lies almost directly behind the plane of the Milky Way, meaning that stars, gas and dust from our home galaxy largely block the view from Earth. NASA's Chandra and the German Extended RÖntgen Survey with an Imaging Telescope Array (eROSITA) X-ray telescope found diffuse, hot gas at the location of the Treble Clef, showing that a galaxy cluster hosts the object.
This new composite image of the Treble Clef and its cluster shows the multimillion-degree gas detected in X-rays by Chandra and eROSITA in blue, with some of the Chandra data derived from a special technique the authors used to highlight important features in the Chandra data. Radio data shown in red from the LOw Frequency ARray (LOFAR), a large network of radio telescopes in Europe, reveals the doppelganger of the musical notation.
First, an earlier outburst from a supermassive black hole in the galaxy cluster's center drove clouds of charged particles and magnetic fields away at close to the speed of light. Botteon et al, The Treble Clef radio phoenix and its old nonthermal filaments, Astronomy & Astrophysics (2026).
