Radio telescopes find 'Treble Clef' in galaxy cluster collision

Astronomers peering past the crowded, dusty plane of the Milky Way have spotted a tangle of radio light, glowing inside a massive collision of lots of galaxies.The space object loops and curls in thin strands, earning its nickname, the Treble Clef. It's what researchers refer to as a "radio phoenix," a cloud of faded particles brought back to life.
